This double-action treatment uses AHA (glycolic acid) and BHA (salicylic acid) at 2% each to tackle blemishes from multiple angles. AHA works on the skin's surface to clear away dead cells, while BHA goes deeper into pores to dissolve buildup—together, they help address breakouts, blackheads, and uneven texture. The pre-soaked cotton pads make it easy to apply exactly where you need it, with included tongs for hygienic use.
Who is This For?
Especially helpful for oily, combination, or acne-prone skin dealing with clogged pores and breakouts, but anyone looking for targeted spot treatment can benefit. If your skin runs dry or sensitive, start slowly and monitor how your skin responds.
Key Benefits
Dual AHA + BHA formula exfoliates both the skin surface and inside pores
Pre-soaked pads allow precise application on problem areas without over-treating the rest of your face
Zinc PCA helps manage excess oil production
Sodium Hyaluronate and Allantoin provide hydration and soothing support during exfoliation
Key Ingredients
Glycolic Acid (AHA) 2% — Exfoliates the skin surface to remove dead cells and smooth texture
Salicylic Acid (BHA) 2% — Penetrates into pores to clear congestion and help prevent future breakouts
Zinc PCA — Helps regulate sebum and control shine
Sodium Hyaluronate — Draws moisture into the skin to offset potential dryness from exfoliation
Allantoin — Soothes and calms skin during the treatment process
FAQs
Q: Can I use the COSRX AHA BHA Blemish Treatment Serum every day?
A: Start with 2-3 times per week and observe how your skin responds before increasing frequency; daily use may cause irritation for some skin types.
Q: Is this product suitable for sensitive skin?
A: This product contains active acids and is formulated for oily and acne-prone skin; those with sensitive or compromised skin barriers should patch test first or consult a dermatologist.
Q: Can I use this with retinol?
A: Avoid using this product and retinol in the same routine; alternate usage on different nights to prevent irritation.
Q: Do I need to wash off this product?
A: No, this is a leave-on treatment; allow it to absorb and follow with your regular moisturizer.
Q: Should I use this in the morning or at night?
A: Nighttime is recommended since AHA can increase sun sensitivity; if you do use it during the day, apply SPF 30 or higher afterward.
Q: How long until I see results?
A: Most users notice improvements in texture and breakouts within 2-4 weeks of consistent use, though individual results vary.
Q: Can I use this all over my face or just on spots?
A: The pre-soaked pads are designed for targeted application on problem areas; using all over may over-exfoliate, especially if you have combination or dry patches.
How to Use
Cleanse and dry your face completely. Remove one cotton pad from the container using the included tongs. Gently tap the soaked cotton pad directly onto targeted blemish areas. For blackheads or whiteheads on the nose and chin, gently wipe the affected area. Allow the product to absorb without rinsing. Follow with moisturizer. Apply sunscreen if using during daytime.
