Dr.Althea Vitamin C Boosting Serum (30ml) — Korean Vegan Brightening Serum with 63% Hippophae Rhamnoides Water, 5% Niacinamide & 2% Tranexamic Acid | 8 Types of Hyaluronic Acid | Fades Dark Spots & Restores Radiant Skin | All Skin Types | Made in Korea

Vitamin C, Reimagined for Sensitive Skin

Pure Vitamin C (L-Ascorbic Acid) is powerful — but it is also one of the most irritating, unstable actives in skincare, often too aggressive for sensitive or reactive skin. The Dr.Althea Vitamin C Boosting Serum, available at thealoy.com, takes a different approach entirely: instead of leading with pure Vitamin C, this New & Improved formula is built around 63% Hippophae Rhamnoides Water — Sea Buckthorn Water naturally rich in Vitamin C — delivering the brightening power of Vitamin C in a form that is mild and gentle while remaining genuinely effective.

This is the foundation of the brand's Vita Boosting Complex 63%, a combination of 9 types of vitamins and Hippophae Rhamnoides Fruit Extract engineered to deliver a high level of Vitamin C to the skin without causing irritation. Layered into this complex: 45,000ppm of a three-ingredient brightening blend — 3-O-Ethyl Ascorbic Acid, D-Panthenol, and Niacinamide — working together to suppress melanin pigmentation and improve skin blemishes, alongside Tranexamic Acid to further fade dark spots and even out skin tone.

Developed under Dr.Althea's clinically focused PRO LAB line, this serum proves that brightening and gentleness do not have to be a trade-off.

Skin Type Suitability

• All skin types, including sensitive skin — formulated without artificial colours or scents for a skin-friendly, gentle experience
• Dull and uneven-toned skin — the primary target; the Vita Boosting Complex is specifically engineered to suppress melanin pigmentation and reveal radiant, even-toned skin
• Dehydrated skin — 8 types of Hyaluronic Acid provide deep, long-lasting hydration at multiple skin levels, from the surface down within the skin itself
• Acne-prone skin — works well for most acne-prone skin types according to verified retailer guidance, though patch testing is recommended given individual skin variation
• Skin prone to irritation from standard Vitamin C serums — milder than standard Vitamin C serums while still offering powerful brightening effects, making it accessible to those who have reacted poorly to pure L-Ascorbic Acid formulas

Who Is This Product For?

• Those dealing with dullness, dark spots, post-acne marks, or uneven skin tone who want a genuinely effective brightening serum without the irritation risk of pure Vitamin C
• People with sensitive skin who have wanted to use Vitamin C but found conventional formulas too harsh or destabilising
• Anyone who wants a single serum addressing brightening, hydration, and soothing simultaneously, rather than layering separate products for each concern
• Those in Bangladesh searching for the best Vitamin C serum for sensitive skin in Bangladesh or the original Dr.Althea Vitamin C Boosting Serum — now at thealoy.com with verified authenticity

Who Should Avoid This Product?

• Those seeking pure, high-strength L-Ascorbic Acid — this serum prioritises gentleness through Hippophae Rhamnoides Water and 3-O-Ethyl Ascorbic Acid rather than pure Ascorbic Acid as the primary Vitamin C source; those wanting maximum-strength pure Vitamin C should look elsewhere
• Those with extremely reactive or compromised skin barriers — while gentler than standard Vitamin C serums, those with very sensitive skin may want to consider Dr.Althea's dedicated Gentle Vitamin C Serum instead, and should always patch test new actives first
• Pregnant women — contains Tranexamic Acid, Niacinamide, and Adenosine; consult your dermatologist before introducing new active serums during pregnancy

Skin Concerns It Helps With

• Dullness and lack of radiance — natural Vitamin C from Hippophae Rhamnoides Water brightens skin without irritation, restoring clear and radiant skin
• Dark spots and hyperpigmentation — Tranexamic Acid effectively improves dark spots and evens out skin tone, working alongside Niacinamide and 3-O-Ethyl Ascorbic Acid's melanin-suppressing action
• Uneven skin tone and texture — the 45,000ppm brightening blend works to even out skin tone and texture, soothe the skin, and diminish blemishes
• Dehydration at multiple skin levels — 8 types of hyaluronic acid provide deep, long-lasting hydration not only to the surface but also within the skin, effectively soothing tired skin affected by external factors
• Fine lines and reduced elasticity — together with Vitamin E, this multi-functional serum helps promote skin cell regeneration, reduce the appearance of fine lines and wrinkles, and improve skin elasticity; Adenosine adds further anti-ageing support
• Sensitive, tired-looking skin — Centella Asiatica Leaf Water soothes and comforts sensitive skin while the overall formula remains free from artificial colours and fragrances

What Results Can You Realistically Expect?

Immediately: The lightweight, stable, non-greasy formula absorbs quickly, leaving skin feeling soft and plump without a sticky feel. Skin appears more hydrated and refreshed from the first application.

With consistent use: Regular twice-daily use supports a progressively brighter, more even-toned complexion as the Vita Boosting Complex and Tranexamic Acid work cumulatively to suppress melanin pigmentation and fade existing dark spots.

Long-term: Continued use supports improved skin elasticity and a reduction in fine lines, alongside sustained brightening and hydration benefits across multiple skin depths.

Individual results may vary depending on skin type, severity of pigmentation, and consistency of use. Always pair with daily SPF for optimal brightening results.

How to Use

1. After cleansing and toning, apply a few drops of the serum to the face
2. Gently pat or massage until fully absorbed
3. Follow with moisturiser
4. Can be incorporated into both day and night routines
5. For daytime use, always follow with sunscreen — this is essential for protecting and maintaining the brightening results

Frequency: Morning and evening, as part of a complete skincare routine.

As the formula's primary base at 63%, it delivers Vitamin C's benefits in a naturally buffered, lower-irritation form compared to pure L-Ascorbic Acid.

Ceramide NP & Bifida Ferment Lysate Skin barrier-supporting ingredients that replenish lipids and support a healthy skin microbiome, helping maintain skin resilience while the brightening actives work.

Bisabolol A naturally derived anti-inflammatory compound that calms and soothes the skin, helping to minimise any potential irritation from the formula's multiple active ingredients.

Frequently Asked Questions

Why does this serum use Hippophae Rhamnoides Water instead of pure Vitamin C? Instead of pure Vitamin C, the formula uses Hippophae Rhamnoides Water and 3-O-Ethyl Ascorbic Acid, a stable form of Vitamin C, which reduces the chances of irritation while still delivering powerful brightening effects. This makes the serum gentler and more suitable for sensitive skin than conventional high-strength Vitamin C formulas.

What is the difference between this serum and Dr.Althea's Gentle Vitamin C Serum? Both serums are designed to brighten and target uneven skin tone, but the Vitamin C Boosting Serum is the more intensive option, containing 63% Hippophae Rhamnoides Water alongside Tranexamic Acid and Niacinamide for stronger brightening action. Those with very sensitive skin who want an even gentler entry point may prefer the Gentle Vitamin C Serum instead.

Is this serum suitable for acne-prone skin? The serum works well for most acne-prone skin types according to verified retailer guidance. As everyone's skin condition is different, a patch test before full facial use is recommended.

Do I need to use sunscreen with this serum? Yes — for daytime use, always follow with sunscreen. This is essential both for general skin protection and for preserving and maximising the serum's brightening results, since UV exposure can trigger new pigmentation that counteracts the treatment.

Is the original Dr.Althea Vitamin C Boosting Serum available in Bangladesh? Yes. Purchase the 100% authentic Dr.Althea Vitamin C Boosting Serum (30ml) directly at thealoy.com — Bangladesh's trusted Korean skincare destination with fast nationwide delivery.

Is this serum vegan? Yes — Dr.Althea Vitamin C Boosting Serum is a vegan-friendly formula, consistent with the brand's overall vegan skincare philosophy.

How long does 30ml last? With twice-daily use of a few drops per application, 30ml typically lasts 6 to 8 weeks.

For external use only. If red spots, swelling, itchiness, or other skin irritations occur during or after use, discontinue use and consult a physician. Avoid direct contact with eyes. Always follow with sunscreen during daytime use. Store away from direct sunlight. Keep out of reach of children.
