Review

Results you may expect from using COSRX AHA 7 Whitehead Power Liquid:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using COSRX AHA 7 Whitehead Power Liquid:

  • Moderate moisturizing. It has a moisturizing rating of 5.0 out of 10.
  • Significant anti-wrinkle efficacy. With an anti-wrinkle rating of 6.0 out of 10, COSRX AHA 7 Whitehead Power Liquid is effective in minimizing wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: COSRX AHA 7 Whitehead Power Liquid has a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Butylene Glycol (est. ≈7.1%) and Niacinamide (est. ≈3.0%).

Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Anti-wrinkle efficacy

According to CreamScan analysis, COSRX AHA 7 Whitehead Power Liquid has a high anti-wrinkle rating of 6.0 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:

  • Niacinamide (est. ≈3.0%),
     one of the most effective and well-researched anti-wrinkle ingredients.
  • Glycolic Acid (est. ≈7.0%),
     highly effective in peelings, yet with below-average anti-wrinkle efficacy when used in leave-on skincare products.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Antioxidant benefits

We estimate that COSRX AHA 7 Whitehead Power Liquid is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈3.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.
