COSRX AHA 7 Whitehead Power Liquid 100ml

Cosrx whitehead power liquid runs on apple fruit water rather than plain water, carrying glycolic acid at the centre of the formula alongside niacinamide and panthenol. It's built for gradual, regular use on texture and closed comedones rather than an occasional strong peel, and the 100ml bottle is designed to be worked in slowly, particularly for anyone new to AHA exfoliants. Sodium hyaluronate sits in the ingredient list to help offset some of the drying effect that acids commonly bring.

Why You'll Love It

• Glycolic acid targets texture and closed comedones without needing a separate peel step in the routine.
• Niacinamide works alongside the acid for an even-looking tone rather than exfoliation being the only benefit.
• Apple fruit water as the base ingredient gives the formula a lighter feel than a plain water-based acid toner.
• Panthenol and sodium hyaluronate help offset the drying effect that acids often bring on their own.

Key Ingredients

• Glycolic Acid: the core AHA exfoliant, working on surface texture and closed comedones.
• Niacinamide: supports an even-looking tone alongside the exfoliating action.
• Panthenol: included for comfort, helping balance the acid's drying tendency.
• Sodium Hyaluronate: adds a layer of hydration to offset moisture loss from regular acid use.

How to Use

Apply to clean, dry skin as directed, avoiding the eye and lip area. Start slowly, two to three times a week, before building up frequency if your skin tolerates it well. Use a moisturiser afterwards, and apply sunscreen every morning you use this product, since AHA exfoliants increase sun sensitivity. Avoid combining with other strong exfoliants in the same routine unless the brand specifically advises it.

Suitable For

With an exfoliating, smoothing and brightening skin-care effect, this suits normal to oily skin dealing with texture, closed comedones or dullness. Sensitive or acid-new skin should patch test and start at a lower frequency before working up to regular use.

FAQ

Q: Do I need sunscreen with Cosrx Whitehead Power Liquid?
Ans: Yes. This is an AHA exfoliant, so daily sunscreen is essential whenever it's used in your routine, not optional.

Q: How often should I use this liquid?
Ans: Start with two to three times a week and build up gradually, rather than using it daily from the start.

Q: Can I use this with other exfoliants?
Ans: It's best not to combine this with other strong exfoliants in the same routine unless the brand specifically advises it, since layering acids can over-strip the skin.

Q: Is this suitable for sensitive skin?
Ans: Sensitive skin can try it, but patch testing first and starting at a lower frequency is the safer approach.

Q: What does the apple fruit water do in this formula?
Ans: It replaces plain water as the base, giving the liquid a lighter feel while the glycolic acid does the exfoliating work.
