About AHA 7 Whitehead Power Liquid

Overview

AHA 7 Whitehead Power Liquid is a watery-light exfoliator from COSRX, a brand based in Korea. The ingredient list runs to 10 ingredients, each broken down in full below.

Texture and finish

By its ingredient list the formula reads as very light — essentially a water-and-humectant base with little emollient weight. With almost no emollient load it should absorb quickly and finish close to matte.

What the formula does

Hydration: Moderate. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Butylene Glycol, Panthenol and Sodium Hyaluronate.

Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide and Glycolic Acid.

Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Panthenol, Niacinamide and Sodium Hyaluronate.

Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Niacinamide and Panthenol.

Who it suits

On richness alone it suits Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.

What it does not target

The formula contributes little or nothing on antioxidant protection and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.

What is not in it

Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.

Where it fits in a routine

Use it in the evening. In a routine it goes after cleansing, before serums. Start at once or twice a week and build up only if skin stays comfortable. Wear sunscreen the next morning — fresh exfoliation raises UV sensitivity.

This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.

What to layer it with

Judged by the same curated rules our routine checker uses. It reads the ingredients, not the label.

Compatible with

  • Azelaic acid
  • Copper peptides
  • Bakuchiol
  • Niacinamide
  • Hyaluronic acid
  • Ceramides
  • Signal peptides
  • Panthenol

Use with caution

  • Retinoids (retinol, retinal)

    Best kept to separate routines — one in the morning, one at night, or on alternate days.

  • Vitamin C (L-ascorbic acid)

    Can be layered, but the combination raises the irritation risk. Go slowly.

  • AHAs (glycolic, lactic)

    Can be layered, but the combination raises the irritation risk. Go slowly.

  • BHA (salicylic acid)

    Can be layered, but the combination raises the irritation risk. Go slowly.

  • PHAs (gluconolactone)

    Can be layered, but the combination raises the irritation risk. Go slowly.

  • Benzoyl peroxide

    Can be layered, but the combination raises the irritation risk. Go slowly.

Where it fits in a routine

Evening
  1. Cleanse
  2. Exfoliate
  3. Treat
  4. Moisturise

This product is the "Exfoliate" step.

  • Start at once or twice a week and build up only if skin stays comfortable.
  • Wear sunscreen the next morning — fresh exfoliation raises UV sensitivity.

Safety and suitability

Flags to check, not verdicts. None of this is medical advice — if you are pregnant, breastfeeding or treating a skin condition, ask a doctor.

Pregnancy and breastfeeding
Nothing in this formula is on the standard pregnancy-caution list. That is not clearance — ask your doctor about anything you use daily.
Fungal acne (malassezia)
No ingredient here is a recognised food source for malassezia.
Sensitive and reactive skin
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
