Does COSRX Centella Blemish Cream work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using COSRX Centella Blemish Cream:

  • Significant moisturizing. It has a moisturizing rating of 7.0 out of 10.

Lightweight moisturizer perfect for oily to normal skin

According to CreamScan analysis, COSRX Centella Blemish Cream is highly moisturizing, with a moisturizing rating of 7.0 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Butylene Glycol (est. ≈9.0%) and Glycerin (est. ≈6.0%), and a moderate occlusivity of 3.9 out of 10, mainly due to the high content of Helianthus Annuus (Sunflower) Seed Oil (est. ≈4.0%) and Dimethicone (est. ≈2.5%).

This type of moisturizer is ideal for people with oily skin who want maximum hydration in a relatively lightweight, non-greasy formula. It combines a significant amount of humectants with a limited amount of occlusive ingredients to boost moisturizing efficacy without feeling too heavy.

This product may also be a good choice for people with normal skin who prefer fast-absorbing textures, as it balances significant moisturizing potential with a relatively lightweight texture.

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

Questionable anti-wrinkle efficacy

According to CreamScan analysis, COSRX Centella Blemish Cream has a zero anti-wrinkle rating.

It contains Centella Asiatica Extract, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Centella Asiatica Extract provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not generate 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.

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

Butylene Glycol
Est. %9
Function

Betaine
Est. %2
Function
Origin
BetaineAn ingredient derived from the sucrose in sugar beets. It has a negative chemical charge and a positive chemical charge on the same molecule. This allows betaine to be hygroscopic or humectant and thus provide moisturization by drawing water to the skin.
