COSRX AHA7 Whitehead Power Liquid is a gentle chemical exfoliant powered by 7% glycolic acid—an alpha hydroxy acid that dissolves the bonds holding dead skin cells together, revealing fresher skin underneath. Formulated with 75% apple fruit water for a lightweight, hydrating feel, this watery liquid absorbs quickly and works to clear congestion and smooth rough texture. Best used at night, or with SPF 30+ if applied in the morning.
Who is This For?
Great for anyone dealing with whiteheads, clogged pores, dullness, or uneven texture. Especially helpful for normal to oily skin, but works well for other skin types looking to refine their complexion with regular exfoliation.
Key Benefits

FAQs
Q: Can I use COSRX AHA7 Whitehead Power Liquid every day?
A: Beginners should start with 1-2 times per week and gradually increase frequency based on skin tolerance; daily use is not recommended for most users due to the 7% glycolic acid concentration.
Q: Do I need to wear sunscreen when using this product?
A: Yes, AHAs increase skin sensitivity to UV rays, so applying broad-spectrum SPF 30 or higher during the day is necessary when using this product.
Q: Can I use this with COSRX BHA Blackhead Power Liquid?
A: These products should not be used in the same routine; alternate between them on different days to avoid over-exfoliation.
Q: Is this product suitable for sensitive skin?
A: This product contains 7% glycolic acid, which may cause irritation for sensitive skin types; a patch test is recommended before full application.
Q: Can I use this with my retinol or vitamin C?
A: It's best to use them on different nights to avoid irritation; if you want both in your routine, alternate evenings or use vitamin C in the morning and this product at night.
Q: How long until I see results?
A: Most users notice smoother texture and fewer whiteheads within 2-4 weeks of consistent use, though individual results vary depending on skin type and concerns.
Q: When should I apply this in my routine?
A: Apply after cleansing and toning on dry skin, before serums and moisturizers; nighttime use is recommended to avoid sun sensitivity during the day.
How to Use
Cleanse face thoroughly and pat dry. Soak a cotton pad with the liquid. Swipe a thin, even layer across the face, avoiding the eye and mouth areas. Allow the product to absorb before proceeding with the next skincare step. If using during daytime, apply a broad-spectrum sunscreen rated SPF 30 or higher as the final step.
My dry, red, sensitive skin absolutely LOVES this product. I can't give it enough stars. I've used it in my morning and night routines for the last week and can't wait to see the benefits over time. Already my skin is more bouncy and hydrated and my typical redness has gone down quite a bit. Will absolutely repurchase.
Sidenote: I've been using this in combination with the Cica Toner and Propolos Light ampuole. I love mixing and matching all the lines to see which combo suits my current skin needs.

Holy grail
I adore this stuff! I will never go without it. It comes through on everything it claims and doesn't leave my skin feeling dry or tight. Immediate results that just get better the longer you use it.
