The Ordinary Niacinamide 10% + Zinc 1% Serum 30ml — High-Strength Blemish Control, Oil Regulation & Pore Refining Formula | Original Skincare in Bangladesh

The Serum That Changed How the World Thinks About Skincare

There are very few skincare products that can genuinely be called world-changing. The Ordinary Niacinamide 10% + Zinc 1% Serum is one of them.

Before this formula arrived, getting 10% Niacinamide in a cleanly formulated, clinically transparent serum meant spending the kind of money that most people couldn't justify for a single bottle. The beauty industry had built a system where the price of a product was determined more by its packaging, its brand prestige, and the weight of its marketing budget than by what was actually inside the bottle. Consumers were overpaying — often dramatically — for active ingredient concentrations that were never disclosed, never verified, and frequently lower than they appeared.

The Ordinary was created to "highlight a lack of integrity around pricing and communication in the world of beauty." It launched in 2016 with a radical proposition: that clinical-grade, high-concentration skincare actives could be sold at honest prices, with every ingredient named, every concentration declared, and every formula held to the same standard regardless of how the bottle looked.

The Niacinamide 10% + Zinc 1% Serum was one of the founding products in that original lineup — and nearly a decade later, it remains among the most used, most recommended, and most clinically respected serums on the planet. The Ordinary was named the World's Most Popular Skincare Brand after a Cosmetify study in 2021 which revealed it garnered over 37 million yearly internet searches — a number driven in no small part by this exact formula.

It is a serum that works. It does what it says. It contains what it claims. And it does all of this at a price that respects the intelligence and the budget of the person buying it.

If you've been looking for a dermatologist-recommended brightening and blemish serum in Bangladesh that is backed by science, proven by millions of users globally, and sold at genuine honest pricing — this is it.

Who Is This Product For?

The Ordinary Niacinamide 10% + Zinc 1% has earned its global following precisely because it works across a genuinely broad range of skin types and concerns. But it is most meaningfully suited to specific profiles.

Oily and acne-prone skin — This is where the serum truly excels. The combination of 10% Niacinamide and 1% Zinc PCA creates one of the most effective over-the-counter sebum-regulating formulas available anywhere at any price point. Clinical testing shows the appearance of pores is minimized in 4 weeks, and the formula helps control oil in 3 days. For anyone whose skin produces excess oil, congests easily, breaks out regularly, and struggles with the combination of active blemishes and post-acne marks simultaneously — this serum addresses all of those concerns within a single lightweight, daily formula.

Combination skin dealing with a greasy T-zone, visible pores across the nose and forehead, and intermittent breakouts will find this serum particularly useful. The water-based formula balances without over-drying, keeping oily zones in check while not stripping drier areas of necessary moisture.

Skin with visible pores, blackheads, and congestion — Pore size is largely determined by genetics, but its visible appearance is heavily influenced by the amount of sebum and debris stretching the pore walls. By regulating sebum production over time, Zinc PCA allows pores to appear less prominent — not because they physically shrink, but because they are no longer being pushed open by excess oil and trapped debris.

Those dealing with uneven skin tone, dark spots, and post-acne marks — Niacinamide at 10% is one of the most evidence-backed brightening actives available in topical skincare. It visibly reduces the appearance of dark spots, post-inflammatory hyperpigmentation, and uneven tone with consistent daily use — making this serum relevant not only for those with active blemish concerns but also for those managing the marks that breakouts leave behind.

Sensitive skin types — Despite its high active concentration, this serum is formulated to be gentle. The formula is alcohol-free, oil-free, silicone-free, vegan, gluten-free, and cruelty-free. The absence of common irritants — artificial fragrances, oils, harsh alcohols, silicones, and parabens — makes it broadly accessible to skin that tends to react negatively to more complex formulations.

Skincare beginners — The formula's intentional simplicity is one of its greatest strengths for first-time active users. With only 11 ingredients, everything in this bottle serves a clear purpose. There is nothing hidden, nothing unnecessary, and nothing that requires a degree in chemistry to understand. It is one of the most approachable high-concentration active serums available for someone beginning a proper skincare routine for the first time.

Women across Bangladesh — particularly in high-heat, high-humidity urban environments like Dhaka, Chittagong, and Sylhet — will find this serum especially relevant. Bangladesh's climate drives excess sebum production, accelerates pore congestion, and creates the conditions in which acne and post-acne discoloration become persistent, year-round concerns. The Ordinary Niacinamide 10% + Zinc 1% addresses all of these concerns simultaneously, in a lightweight texture that performs in humid conditions without feeling heavy or occlusive.

Who Should Be Cautious With This Product?

This formula is designed to be broadly tolerable, but certain individuals should proceed thoughtfully.

Niacinamide sensitivity — While Niacinamide is one of the most universally well-tolerated skincare actives, a small percentage of individuals may experience mild flushing, tingling, or temporary redness — particularly during the first few days of use at 10% concentration. In very rare cases, some individuals may not be able to tolerate niacinamide at all or experience an allergic reaction to it. If you have never used Niacinamide before, a patch test before full facial application is always recommended. Apply a small amount to the inner wrist or behind the ear and observe for 24–48 hours.

Vitamin C users — This is one of the most important compatibility notes for this serum. If topical Vitamin C (L-Ascorbic Acid or Ethylated L-Ascorbic Acid) is used as part of skincare, it should be applied at alternate times with this formula — ideally Vitamin C in the PM and this formula in the AM. Otherwise, Niacinamide can affect the integrity of the Vitamin C. This does not mean you cannot use both — it simply means you should separate them into different routine slots.

Severely dry or dehydrated skin — This is an oil-control and blemish serum. Its water-based, lightweight formula is not designed to provide intensive moisture, and those with chronically dry or severely dehydrated skin may need to pair it with a richer moisturizer. The serum supports barrier function over time but should be followed by a moisturizer that addresses your skin's hydration needs directly.

Severely compromised skin barrier — If your skin barrier is actively damaged — stinging, burning, or unusually reactive to products that are normally non-irritating — allow your barrier to heal before introducing any high-concentration active. This formula is gentle, but introducing it during an acute barrier disruption can worsen sensitivity.

Pregnancy and breastfeeding — Niacinamide and Zinc PCA at the concentrations used in this formula are generally considered safe for use during pregnancy and breastfeeding. However, as with any new skincare product used during this period, consulting your doctor or a licensed dermatologist before beginning use is always the responsible approach.

Skin Concerns This Serum Helps Address

The Ordinary Niacinamide 10% + Zinc 1% is not a specialist serum targeting a single concern. It is a comprehensive daily treatment that addresses multiple interconnected skin concerns through the synergistic action of its two key actives.

Excess Oil and Persistent Shine — This is the serum's most immediate and consistently reported benefit. Clinical testing shows Zinc PCA helps control oil in as little as 3 days. For those who struggle with a greasy complexion by midday — particularly during Bangladesh's hot, humid months — this reduction in surface sebum is often the first visible change users notice, and it happens remarkably quickly.

Enlarged and Visible Pores — Zinc PCA regulates the sebum production that stretches and distends pore walls, while Niacinamide improves the overall skin texture that makes pores more visible. Clinical testing shows the appearance of pores is minimized in 4 weeks, improving signs of congestion. With consistent use, pores appear smaller and skin looks more refined.

Blackheads and Whiteheads — The sebum regulation provided by Zinc PCA over time reduces the excess oil that combines with dead skin cells to form comedones. While this serum is not a direct exfoliant, its sebum-controlling action addresses one of the primary conditions that leads to blackhead and whitehead formation.

Active Blemishes and Acne-Related Congestion — Zinc PCA has demonstrated antimicrobial activity against P. acnes (the primary bacteria responsible for inflammatory acne) in laboratory studies. Combined with Niacinamide's anti-inflammatory properties that reduce the redness and swelling associated with active blemishes, this serum creates a skin environment that is less hospitable to breakout formation and less visibly inflamed when blemishes do occur. Note: Niacinamide and Zinc PCA is not a treatment for acne. For persistent acne-related conditions, speaking to a healthcare provider regarding treatment options is recommended. This formulation can be used alongside acne treatments if desired for added visible skin benefits.

Dark Spots and Post-Acne Marks (PIH) — Niacinamide at 10% works by inhibiting the transfer of melanin to the skin's surface — the process by which post-inflammatory hyperpigmentation forms and deepens into visible dark marks. With consistent use, existing post-acne marks fade and new pigmentation is less likely to develop following future breakouts.

Uneven Skin Tone and Dullness — Niacinamide 10% + Zinc 1% visibly improves skin radiance and smooths texture in one week. The skin-brightening effect of high-concentration Niacinamide comes from its combined ability to suppress melanin transfer, improve surface cell turnover support, and strengthen the barrier that keeps skin looking healthy and luminous rather than flat and dull.

Weak Skin Barrier — This serum is a water-based formulation designed to enhance skin brightness, improve texture, and strengthen the skin's moisture barrier. Niacinamide at 10% actively supports the production of ceramides and other barrier lipids that keep moisture in and environmental aggressors out — making this serum genuinely supportive of long-term barrier health, not merely a surface treatment.

Rough Skin Texture — The combination of sebum regulation, barrier strengthening, and the polysaccharide-based texture agents in the formula (Tamarindus Indica Seed Gum, Xanthan Gum) contributes to a progressively smoother skin surface with consistent daily use.

Fine Lines and Early Signs of Aging — Based on in-vitro findings, Zinc PCA may be a promising anti-aging active that helps with the production of type I collagen. Niacinamide at clinical concentrations also supports collagen synthesis, improves skin elasticity, and helps counteract the visible signs of photo-aging that accumulate from years of sun exposure — particularly relevant for Bangladesh, where UV intensity is high for much of the year.

Redness and Skin Sensitivity — Niacinamide's well-documented anti-inflammatory properties reduce the visible redness associated with active blemishes, rosacea-like flushing, and general skin reactivity. Many users with chronic redness report meaningful improvement with consistent use over several weeks.

Realistic Results — What to Expect and When

The Ordinary's approach to communication is built on honesty, and this description reflects that same standard.

First 3 Days — Sebum regulation begins remarkably early. Many users notice a visible reduction in surface oiliness within the first 2 to 3 days of use — one of the fastest-acting benefits of Zinc PCA and one of the most frequently reported first observations from new users.

First 7 Days — Users should notice smoother skin texture after 15 minutes, improvement in plumpness, suppleness, and skin radiance. In 1 week, smoother skin texture is expected. Overall skin clarity often begins to improve, and the matte, balanced quality of the skin throughout the day becomes increasingly apparent.

2 Weeks of Consistent Use — The skin's overall tone starts to look more balanced. Early-stage post-acne marks may begin to show subtle fading. Pore appearance often starts improving as sebum regulation becomes more established.

4 Weeks and Beyond — Clinical testing shows the appearance of pores is minimized in 4 weeks. Dark spots and post-acne marks typically show meaningful visible improvement around this period with consistent twice-daily use. Skin texture is noticeably smoother and more even. For those with more established or deeper pigmentation, the full benefit of Niacinamide's brightening action becomes most apparent in the 6 to 8 week range.

Important: Results will vary depending on skin type, current skin condition, consistency of use, sun exposure habits, and the rest of your skincare routine. All timeline references above are based on clinical study data from The Ordinary's own testing with 35 subjects applying the product twice daily for 8 weeks. Individual results are not guaranteed. This is honest information, not a promise.

How to Use

Morning and Evening — This serum is designed and clinically tested for twice-daily use — once in the morning and once at night.

Step-by-Step Application:

1. Begin with a clean, freshly washed face. If you use a toner, apply it first and allow it to absorb.
2. Dispense 2–3 drops of the serum from the dropper onto your fingertips.
3. Apply across the entire face — or concentrate on specific areas of concern such as the T-zone, visible pores, or areas of post-acne discoloration.
4. Pat the serum gently into the skin. Avoid rubbing or dragging, which can cause unnecessary friction on the skin.
5. Allow the serum to absorb fully — approximately 30 to 60 seconds — before applying your next skincare step.
6. Follow with your moisturizer to seal in the serum and complete your routine.
7. In the morning, always finish with a broad-spectrum SPF 30 or higher sunscreen before stepping outside.

The Vitamin C Rule — Important: If your routine includes a Vitamin C product containing L-Ascorbic Acid or Ethylated L-Ascorbic Acid, do not apply it in the same routine step as this serum. Use Vitamin C in your PM routine and this Niacinamide serum in your AM routine — or vice versa — to maintain the integrity of both actives.

Layering Order: This is a water-based serum. Apply it before heavier, oil-based products, treatments, or moisturizers. Follow the general principle of lightest to heaviest in your layering order.

Sunscreen Reminder: Niacinamide helps fade existing dark spots, but unprotected sun exposure continuously creates new ones. Daily broad-spectrum SPF is essential — without it, you are working against your own progress. This applies to every skin type, every day, regardless of weather.

Beginner Guidance: If this is your first high-concentration active serum, you can begin with once-daily use (evening preferred) for the first week before moving to twice daily. This allows your skin to adjust gradually and makes the overall experience more comfortable.

Ingredient Breakdown — Eleven Ingredients, Zero Waste

One of the most distinctive things about The Ordinary's formula design philosophy is what it leaves out. With only 11 ingredients, every single component in the Niacinamide 10% + Zinc 1% Serum is there for a reason.

Niacinamide 10% (Vitamin B3) — The primary active and the formula's foundational ingredient. At 10%, this is a high-strength concentration that delivers the full breadth of Niacinamide's clinically documented benefits. It works by converting to NAD (nicotinamide adenine dinucleotide) in the skin — a coenzyme that powers skin cell repair, supports collagen production, strengthens the lipid barrier, and fights oxidative stress from UV and environmental pollution. Specifically for brightening, Niacinamide inhibits the transfer of melanin vesicles from pigment-producing cells to surface skin cells — the mechanism by which dark spots form and deepen. For oil control, it reduces the size and activity of sebaceous glands. For barrier health, it stimulates the production of ceramides and other barrier lipids. Few single ingredients offer this depth of multi-benefit activity at a single concentration.

Zinc PCA 1% — The mineral partner that makes this formula's sebum-control credentials genuinely exceptional. Zinc PCA is a synergistic compound combining Zinc — which normalizes sebum production and has antimicrobial activity against acne-causing bacteria — with L-PCA (pyrrolidone carboxylic acid), a natural moisturizing factor found in the skin that helps with hydration and simultaneously increases the bioavailability and efficacy of the Zinc. Together, they regulate oil production without causing dryness, which is why this serum controls shine without leaving skin feeling stripped or tight. An in-vivo test done by the manufacturer shows that Zinc PCA reduces sebum production statistically significantly after 28 days of application.

Pentylene Glycol — A multifunctional humectant derived from sugar beets. It draws moisture from the environment to the skin's surface, provides a smooth, soft texture to the formula, and acts as a mild antimicrobial that contributes to the formula's preservation system. It is what gives this serum its pleasantly lightweight, glide-on feel.

Dimethyl Isosorbide — A penetration-enhancing ingredient that acts as a superior solubilizer and delivery vehicle for active ingredients. Its presence in this formula helps ensure that the Niacinamide and Zinc PCA are delivered more efficiently into the skin, rather than simply sitting on the surface. It improves the bioavailability of the actives — meaning the formula works more effectively per application than a comparable formula without it.

Tamarindus Indica Seed Gum — A natural polysaccharide (complex carbohydrate) derived from tamarind seeds. It moisturizes, smoothes skin texture, improves the formula's sensory feel, and contributes to its elegant, non-sticky finish. According to ingredient research, it also improves skin elasticity with consistent use — adding a subtle long-term skin quality benefit to what is primarily a functional active formula.

Xanthan Gum — A widely used, well-tolerated thickening and emulsion-stabilizing agent that gives the serum its stable, consistent gel-like texture. It holds the formula together without being heavy on the skin.

Isoceteth-20 — A mild emulsifier and solubilizing agent that helps ensure the water-soluble and oil-soluble components of the formula remain evenly distributed and stable over the product's shelf life.

Ethoxydiglycol — A solubilizer that boosts the performance and delivery of active ingredients within the formula. It helps actives penetrate deeper into the skin's layers rather than remaining at the surface, improving the overall efficacy of the formula per use.

Phenoxyethanol and Chlorphenesin — The preservation system that keeps the formula stable, free from microbial contamination, and safe throughout its shelf life. Both are widely used, well-studied preservatives that are considered safe at the concentrations used in leave-on skincare products.

What This Formula Does NOT Contain: No artificial fragrances. No parabens. No mineral oils. No silicones. No harsh alcohols. No sulfates. No gluten. Not tested on animals. Vegan certified.

The elegance of this formula is its intentionality. Every ingredient serves a specific, documented function. There is no filler. There is nothing included for the sake of making the ingredient list look impressive. This is formulation with genuine integrity — the principle on which The Ordinary was founded and the standard this product has upheld since 2016.

About The Ordinary — The Brand That Disrupted an Entire Industry

Founded by the visionary Brandon Truaxe under the umbrella of DECIEM, The Ordinary set out to disrupt the industry by offering clinical formulations with integrity.

DECIEM launched The Ordinary in August 2016 with an impressive 27-product lineup, including several formulas that remain bestsellers nearly a decade later. The Niacinamide 10% + Zinc 1% was among those original 27 products — and it remains one of the brand's most defining formulas to this day.

The brand's founding philosophy was simple but radical for its time. The beauty industry had normalized a system where products were priced based on brand prestige and marketing investment rather than ingredient quality or concentration. Consumers had no reliable way to verify what was actually in their skincare — concentrations were hidden, actives were underdisclosed, and pricing bore no meaningful relationship to formulation.

DECIEM stated: "The brand was created to celebrate integrity in its most humble and true form. Its offering is pioneering, not in the familiar technologies it uses, but in its honesty and integrity. The Ordinary is born to disallow commodity to be disguised as ingenuity."

The result was a brand that named every active, declared every concentration, priced every product based on what the formula actually cost to produce, and refused to use its packaging or marketing as a substitute for formulation quality.

The Ordinary began collecting accolades including #1 Global Prestige Skincare Brand in Units and #1 Share of Voice in Serums just six years after inception. The Ordinary has evolved into a multi-billion-dollar brand, with its parent company DECIEM being valued at over $2.2 billion when Estée Lauder completed its acquisition in 2024.

Today, The Ordinary is sold in Sephora, Ulta, Boots, and hundreds of authorized retailers across more than 40 countries. It is the brand that made clinical-grade skincare accessible to everyone — not as a compromise, but as a standard.

For anyone in Bangladesh looking for original, dermatologist-trusted skincare with verified ingredients, declared concentrations, and honest pricing — The Ordinary is the benchmark.

Frequently Asked Questions

What makes The Ordinary Niacinamide 10% + Zinc 1% different from other Niacinamide serums available in Bangladesh? The primary difference is formulation integrity. The Ordinary declares its concentrations precisely — 10% Niacinamide and 1% Zinc PCA — and its formula has been clinically tested with published results. Many competing products do not disclose their Niacinamide concentration at all, or use concentrations far lower than their marketing implies. With The Ordinary, you know exactly what you're getting. Additionally, the inclusion of Dimethyl Isosorbide as a penetration enhancer improves the bioavailability of the actives — meaning the formula delivers its results more efficiently per application than many comparable products.

Can I use this serum if I have both oily skin and dark spots? Yes — and this is actually one of the ideal use cases for this formula. Niacinamide at 10% addresses both concerns simultaneously, regulating sebum production while inhibiting melanin transfer that creates and deepens dark spots. For more stubborn or deeper pigmentation, pairing this serum with a dedicated brightening treatment (such as a serum containing Tranexamic Acid or Alpha-Arbutin) in alternating routines can provide enhanced results.

Can I use this serum with Vitamin C? Yes, but not in the same routine step. Use Vitamin C (L-Ascorbic Acid or Ethylated L-Ascorbic Acid) in one part of your daily routine — typically the evening — and this Niacinamide serum at a different time, typically the morning. Applying them simultaneously can compromise the stability and effectiveness of the Vitamin C. Stable Vitamin C derivatives (such as 3-O-Ethyl Ascorbic Acid) are generally more compatible and can typically be used in the same routine without issue.

How long will a 30ml bottle last? With twice-daily use and 2–3 drops per application, a 30ml bottle typically lasts approximately 2 to 3 months. The dropper format allows precise, controlled dispensing that minimizes product waste.

Is this serum suitable for teenage skin dealing with acne and oiliness? Yes. The Ordinary Niacinamide 10% + Zinc 1% is one of the most consistently recommended serums for teenage and young adult skin experiencing excess oil, frequent breakouts, and the post-acne marks that follow. Its clean, fragrance-free, non-comedogenic formula is particularly appropriate for younger skin that may not yet have the tolerance for more aggressive active treatments.

Does this serum help with acne scars? It addresses post-acne marks caused by post-inflammatory hyperpigmentation (PIH) — the flat, discolored marks left after a blemish heals. These are not true scars (which involve changes in skin texture and structure) but rather surface discoloration. For PIH, Niacinamide at 10% is clinically effective with consistent use. For true atrophic acne scarring (indentations, icepick or boxcar scars), this serum alone is not sufficient — those conditions require dermatological treatments such as chemical peels, microneedling, or laser.

Is this product suitable for Bangladesh's hot and humid climate? Absolutely. The lightweight, water-based, oil-free formula is specifically well-suited to humid climates where heavy serums and creams feel uncomfortable and congesting. It absorbs quickly, leaves no greasy residue, and controls the excess sebum that Bangladesh's heat and humidity accelerates — making it one of the most climate-appropriate serums available for everyday use in Bangladesh.

Where can I buy the original The Ordinary Niacinamide 10% + Zinc 1% in Bangladesh? The authentic formula is available at thealoy.com — one of Bangladesh's most trusted destinations for original skincare products online. Every product carried on our platform is sourced from verified, reliable suppliers to ensure complete authenticity and customer confidence.

For persistent acne, deep hyperpigmentation, or any diagnosed skin condition, we always recommend consulting a licensed dermatologist in addition to any over-the-counter skincare routine.
