Does COSRX AC Collection Blemish Spot Drying Lotion work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using COSRX AC Collection Blemish Spot Drying Lotion:

  • Moderate moisturizing. It has a moisturizing rating of 4.0 out of 10.
  • Some anti-wrinkle efficacy: COSRX AC Collection Blemish Spot Drying Lotion has an anti-wrinkle rating of 3.0 out of 10 so you may expect some, although limited, effect on wrinkles.

Lightweight moisturizer ideal for oily skin and a humectant boost for any skincare routine

According to CreamScan analysis, COSRX AC Collection Blemish Spot Drying Lotion is quite moisturizing, with a moisturizing rating of 4.0 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a very high humectancy of 8.0 out of 10, due to the high content of Glycerin (est. ≈6.0%) and Butylene Glycol (est. ≈2.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

Tip: Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

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

Some anti-wrinkle efficacy

According to CreamScan analysis, COSRX AC Collection Blemish Spot Drying Lotion has a slight anti-wrinkle rating of 3.0 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Asiaticoside (est. ≈0.3%), 
 derived from the plant Centella asiatica, an ingredient with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 27 participants (Lee et al.). This study demonstrated that a cream containing 0.1% asiaticoside reduced the average wrinkle depth by 8% after 12 weeks of use, compared to a vehicle (the same formulation without asiaticoside).
 
Among others, COSRX AC Collection Blemish Spot Drying Lotion also contains contains Madecassic Acid and Centella Asiatica Extract, two ingredients often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. Therefore, these ingredients do not contribute to the anti-wrinkle rating.
 
Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.
