Key Benefits of COSRX AC Collection Acne Patch

 
These are the key benefits you can expect from using COSRX AC Collection Acne Patch:
 

🔵🔵 Moisturizer with the Right Occlusivity for Normal Skin

According to CreamScan analysis, COSRX AC Collection Acne 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.

🍀 Rich in Skin-Protecting Antioxidants

We estimate that COSRX AC Collection Acne Patch is rich (> 3%) in antioxidants, specifically Centella Asiatica Extract (est. ≈10.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

🔴 Skin Soothing and Calming Potential

Based on the ingredient list analysis, COSRX AC Collection Acne Patch is rich (> 5%) in soothing ingredients, particularly Centella Asiatica Extract (est. ≈10.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.

📌 Please note that this is not a complete list of benefits. We are in the process of enhancing our model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: COSRX AC Collection Acne Patch

 
CreamScan identified a few things to consider before adding COSRX AC Collection Acne 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 AC Collection Acne 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.

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing COSRX AC Collection Acne Patch is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently 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.

While this does not categorically rule out the possibility that Centella Asiatica Extract may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.

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.
