Moisturizer with the Right Occlusivity for Normal Skin

According to CreamScan analysis, COSRX Acne Pimple Master Patch is lightly moisturizing, with a moisturizing rating of 2.5 out of 10.

Is it more humectant or occlusive? Purely occlusive. It has zero humectancy (we didn't find any humectant ingredients on the ingredient list) and a moderate occlusivity of 5.0 out of 10, entirely due to the high content of Mineral Oil (est. ≈10.0%).

This type of product, when used as a standalone moisturizer, may provide some occlusive moisturizing that is adequate for normal skin.

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

Things to Be Aware Of: COSRX Acne Pimple Master Patch

CreamScan AI identified a few things to consider before adding COSRX Acne Pimple Master Patch to your skincare routine:

Needs to Be Paired with Extra Humectants for Optimal Moisturizing Efficacy

An ideal moisturizer for any skin type should balance the right level of occlusivity (depending on skin type) with a significant amount of humectants, while COSRX Acne Pimple Master Patch contains no humectants at all.

People with normal skin would definitely benefit from adding water-binding humectants to their moisturizing routine for effective dual-action moisturizing. If this is your only moisturizer, it may be worth including a humectant-rich product, such as a serum, in your skincare routine.

According to studies, hovewer, even 10% petrolatum can achieve almost the same mosturizing effect. The occlusive properties of petrolatum are at least twice as superior as other occlusive ingredients. This is why, in order to match the moisturizing efficacy of 10% petrolatum, a product needs to contain at least 20% of other occlusives. Our benchmark for maximum Occlusivity is 20 (and the petrolatum score is always doubled). The most occlusive product possible is 100% petrolatum (hello Vaseline Jelly).
