Stacked Skincare TCA Multi-Acid Face Peel | Unbiased Skincare Efficacy Review by AI

Review

Does Stacked Skincare TCA Multi-Acid Face Peel work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Stacked Skincare TCA Multi-Acid Face Peel:

Light moisturizing. It has a moisturizing rating of 3.6 out of 10.

Little anti-wrinkle effect: Stacked Skincare TCA Multi-Acid Face Peel has an anti-wrinkle rating of 1.5 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.

Lightweight moisturizer well-suited for oily skin and a humectant enhancement for any skincare routine

According to CreamScan analysis, Stacked Skincare TCA Multi-Acid Face Peel is lightly moisturizing, with a moisturizing rating of 3.6 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 7.3 out of 10, primarily due to the high content of Lactic Acid (est. ≈4.0%) and Propanediol (est. ≈2.0%).

This humectant-rich product, when used alone as a moisturizer, is well-suited for oily skin, providing moderate 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 enhancement 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.

Little anti-wrinkle efficacy

According to CreamScan analysis, Stacked Skincare TCA Multi-Acid Face Peel has a minimal anti-wrinkle rating of 1.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈6.0%),

a highly effective ingredient in peelings but with moderate anti-wrinkle efficacy in leave-on skincare products, as supported by a single clinical study. This study, involving 72 participants (Thibault et al.), demonstrated that a lotion with 5% GA reduced the fine wrinkling score by 6% after 34 days of use, compared to a vehicle (the same formulation without GA).

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.
