COSRX AHA/BHA Clarifying Treatment Toner (30ml) — Korean Gentle Exfoliating Toner with 0.1% Glycolic Acid, Betaine Salicylate, 10% Willow Bark Water & Apple Fruit Water | Clears Pores, Removes Dullness & Smooths Texture | Daily Use | All Skin Types | Vegan | Made in Korea
Minimal Ingredients. Maximum Effect. Daily.
Most AHA/BHA products come with a long list of warnings: do not use more than twice a week, introduce gradually, expect irritation. The COSRX AHA/BHA Clarifying Treatment Toner, available at thealoy.com, takes a different approach — formulated specifically for daily use with actives calibrated at a gentle concentration that exfoliates and clarifies without disrupting the skin barrier.
With just 11 carefully selected ingredients, this is a toner that works through intelligent formulation rather than ingredient complexity. The AHA and BHA concentrations are deliberately mild (0.1% each) — low enough for beginners and sensitive skin, yet consistently effective through daily use for exfoliation, pore clarity, and texture improvement. The mineral-rich Willow Bark Water and Apple Fruit Water replace purified water entirely, delivering natural exfoliating botanical acids as the formula's hydrating base.
The 30ml bottle is the trial and travel size — perfect for first-time users before committing to the 150ml full size.
Skin Type Suitability
- All skin types — dermatologically tested; 0.1% concentration specifically formulated for daily use including sensitive skin
- Oily and combination skin — Betaine Salicylate clears congested pores and balances sebum production
- Acne-prone and blemish-prone skin — Willow Bark Water and Betaine Salicylate reduce breakouts and marks; Glycolic Acid prevents dead cell buildup that contributes to congestion
- Dull and rough skin — Glycolic Acid exfoliates the skin surface and smooths texture; Apple Fruit Water provides gentle brightening
- Sensitive skin — the low 0.1% active concentration and Allantoin + Panthenol support system make this the most beginner and sensitive-skin appropriate AHA/BHA toner available
Who Is This Product For?
- Beginners to chemical exfoliation who want to introduce AHA and BHA into their routine safely, with zero risk of the burning, peeling, or over-exfoliation that higher-concentration products can cause
- Those who want a single daily toner that simultaneously exfoliates, clarifies pores, brightens, and balances oil without needing separate treatment products
- People with congested pores, blackheads, rough texture, or dull skin who have been unsure where to start with exfoliating acids
- Anyone in Bangladesh searching for the best AHA BHA toner for beginners in Bangladesh or the original COSRX exfoliating toner in Bangladesh — now at thealoy.com with verified authenticity
Who Should Avoid This Product?
- Those with active, open, or severely inflamed acne lesions — do not apply directly to broken or actively inflamed skin; use around those areas
- Those who skip SPF — AHA (Glycolic Acid) increases sun sensitivity. Always follow with broad-spectrum SPF 30 or higher during daytime use. Skipping SPF while using AHA will worsen the very pigmentation and damage you are trying to address
- Pregnant women — contains Glycolic Acid and Betaine Salicylate; consult your dermatologist or OB-GYN before introducing exfoliating acids during pregnancy
Skin Concerns It Helps With
- Dullness and dead skin cell accumulation — 0.1% Glycolic Acid (AHA) exfoliates the surface, removing the layer of dead cells that causes flat, dull, congested-looking skin
- Congested pores and blackheads — Betaine Salicylate (BHA) penetrates oil in the pore to clear congestion, reduce blackhead formation, and minimise pore appearance
- Rough and uneven skin texture — Glycolic Acid smooths and softens the skin surface with consistent daily use
- Oil imbalance and breakouts — Betaine Salicylate balances oil production and reduces the bacterial environment that contributes to breakouts; Willow Bark Water offers gentle natural antibacterial support
- Post-acne marks and hyperpigmentation — Glycolic Acid's cell turnover acceleration helps bring fresher, more evenly-pigmented cells to the surface over time
- Skin dehydration — Sodium Lactate, Panthenol, and the mineral-rich botanical water base maintain moisture throughout the exfoliation process
What Results Can You Realistically Expect?
Immediately: Lightweight, water-type toner applies effortlessly. Skin feels refreshed, slightly tightened, and noticeably cleaner after the first use. No burning, tingling, or redness at the 0.1% concentration.
Within 2 to 4 weeks: Skin texture progressively smooths. Pores appear less congested. Complexion looks more even and brighter on a daily basis. Blackheads may reduce in frequency and visibility.
Long-term: Consistent daily exfoliation produces a cumulative improvement in skin clarity, tone, and texture. Post-acne marks fade more quickly as cell turnover accelerates.
Always use SPF in the morning. Results vary with skin type and consistency.
How to Use
- After cleansing, spray the toner onto a cotton pad
- Gently wipe across the face from the inner areas outward, avoiding the eye and mouth area
- Do not rinse — leave the toner on the skin
- Follow with serum, moisturiser, and SPF (morning)
- Can also be saturated onto a cotton pad and left as a toner mask for 5–10 minutes for immediate hydration
Frequency: Morning and/or evening after cleansing.
SPF is mandatory during daytime use with AHA — this is non-negotiable.
Ingredient Breakdown
Full Official Ingredient List:
Water, Salix Alba (Willow) Bark Water, Pyrus Malus (Apple) Fruit Water, Butylene Glycol, 1,2-Hexanediol, Sodium Lactate, Glycolic Acid, Betaine Salicylate, Allantoin, Panthenol, Ethyl Hexanediol
Glycolic Acid (AHA — 0.1%)
The AHA component. Glycolic Acid is the smallest alpha-hydroxy acid molecule, giving it the best skin penetration of all AHAs. It exfoliates the surface of the skin by dissolving the bonds between dead keratinocytes, allowing them to shed more effectively. This reveals fresher skin underneath, improves texture, brightens dullness, and over time accelerates the fading of post-acne marks and uneven pigmentation. At 0.1%, the concentration is gentle enough for daily use without the sensitivity risks of higher-strength AHA products.
Betaine Salicylate (BHA)
A gentler form of Salicylic Acid — a BHA combined with Betaine for reduced irritation potential compared to standard Salicylic Acid. Like all BHAs, it is oil-soluble, meaning it can penetrate into the sebum-filled pore lining to dissolve the buildup of dead skin cells and excess oil that forms blackheads and congestion. At 0.1%, it clears congested pores and balances oil production without the dryness and peeling of stronger BHA concentrations.
Salix Alba (Willow) Bark Water (10%)
Natural mineral-rich water derived from white willow bark — which naturally contains salicin, a precursor to salicylic acid. Offers gentle natural exfoliation, helps reduce breakouts and marks from spots, and provides natural antimicrobial support. Replaces a portion of the formula's water content for added botanical benefit.
Pyrus Malus (Apple) Fruit Water (10%)
Water derived from apple fruit — naturally rich in malic acid (a gentle AHA) and antioxidant polyphenols. A natural plant-derived acid that relieves irritation while exfoliating the skin. Works synergistically with the Glycolic Acid to provide gentle brightening and texture improvement.
Sodium Lactate
A naturally derived humectant (from lactic acid fermentation) that draws and retains moisture in the skin, preventing the dryness that exfoliating acids can occasionally cause. Also provides a gentle moisturising AHA effect through its lactate component.
Allantoin
Soothes irritation, promotes cell regeneration, and ensures the formula is comfortable even on reactive skin. An important soothing counterbalance to the exfoliating actives.
Panthenol (Vitamin B5)
Supports barrier repair and moisture retention — ensuring that the daily exfoliation process does not compromise the skin's protective barrier over time.

Frequently Asked Questions
Is this toner safe for daily use?
Yes — it is specifically formulated and recommended for daily use (morning and/or evening). The 0.1% AHA and BHA concentrations are gentle enough for everyday exfoliation without the barrier disruption or sensitivity risks of higher-strength products.
What is the difference between AHA and BHA, and why do I need both?
AHA (Glycolic Acid) is water-soluble and works on the skin's surface — it exfoliates dead skin cells, improves texture, and brightens. BHA (Betaine Salicylate) is oil-soluble and penetrates into the pore — it clears sebum buildup, reduces congestion, and minimises blackheads. Using both simultaneously addresses both surface texture and pore clarity, which is why this combined formula is more comprehensive than single-acid toners.
Do I need SPF when using this toner?
Yes — this is essential. AHA (Glycolic Acid) increases UV sensitivity. Always apply a broad-spectrum SPF 30 or higher in the morning when using this toner during the day. Skipping SPF will make your skin more vulnerable to UV damage and counteract the brightening benefits.
Is the 30ml the same formula as the 150ml?
Yes — the 30ml is the identical formula in a smaller trial and travel size. It contains the same 11 ingredients at the same concentrations.
Is the original COSRX AHA/BHA Toner available in Bangladesh?
Yes. Purchase the 100% authentic COSRX AHA/BHA Clarifying Treatment Toner (30ml) directly at thealoy.com — Bangladesh's trusted Korean skincare destination with fast nationwide delivery.
How long does 30ml last?
With daily use on a cotton pad, 30ml typically lasts 3 to 5 weeks. It is the ideal size for first-time users before switching to the 150ml full size.
For external use only. Avoid direct contact with eyes and mouth area. Do not use on broken or inflamed skin. Always apply SPF during daytime use with AHA. Discontinue use if irritation occurs. Store in a cool, dry place. Keep out of reach of children.
