SEPHORA COLLECTION Clear Skin Days by Sephora Collection Clarifying Serum | Review, Efficacy Ratings, Ingredient List Explained

Review

Results you may expect from using SEPHORA COLLECTION Clear Skin Days by Sephora Collection Clarifying Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using SEPHORA COLLECTION Clear Skin Days by Sephora Collection Clarifying Serum:

Light moisturizing. It has a moisturizing rating of 3.3 out of 10.

Little anti-wrinkle effect: SEPHORA COLLECTION Clear Skin Days by Sephora Collection Clarifying Serum has an anti-wrinkle rating of 1.2 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.

How moisturizing is it?

Lightly moisturizing: SEPHORA COLLECTION Clear Skin Days by Sephora Collection Clarifying Serum has a moisturizing rating of 3.3 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 high humectancy of 6.6 out of 10, primarily due to the high content of Propanediol (est. ≈6.0%).

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, SEPHORA COLLECTION Clear Skin Days by Sephora Collection Clarifying Serum has a minimal anti-wrinkle rating of 1.2 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈4.0%),

highly effective in peelings, yet with below-average anti-wrinkle efficacy when used in leave-on skincare products.

Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, could deliver additional anti-wrinkle efficacy through its moisturizing action.
