CosRX Acne Pimple Master Patch ingredient review

Stickers that cure your acne sound too good to be true – which is why they don’t exist, but the next to best thing does! Enter CosRX Acne Pimple Master Patches, a $5 product that has helped my skin on numerous occasions. These pimple patches come in three different sizes, with 24 patches per pack (so definitely worth the price). The hydrocolloid patch is meant to be placed over an emerging pimple to sit overnight. In the morning the pimple should be significantly less inflamed, with reduced redness and size. As a user of these (cute) little patches, I can confirm this is all true.

ingredient review

ingredients: Cellulose Gum, Styrene Isoprene Styrene Block Copolymer, Polyisobutylene, Petroleum Resin, Polyurethane Film, Liquid Paraffin, Tetrakis Methane

So what exactly makes these little patches so effective? As you can see from the ingredient list above, there are only a few ingredients in this product, none of which appear to be acne fighters like salicylic acid or sulfur. So let’s break it down ingredient by ingredient:

Cellulose Gum is a thickening agent, most likely used to help create the patch structure themselves. In addition to being a thickening agent, cellulose gum is used to retain moisture, increase stability and provide volume and texture

Styrene Isoprene Styrene Block Copolymer is a polymer with a rubber-like consistency that makes up the main structure of these patches

Polyisobutylene is a synthetic rubber used in many industries. For example, food-grade polyisobutylene is used as the base for many chewing gum formulas

Petroleum Resin is a hydrocarbon compound also used in many industry settings due to its ability to provide a tackiness to a material. So for these patches, the resin is what allows them to essentially become stickers

– Polyurethane Film is technically not used in the formulation of this product, but rather is a protective film (made from a polymer) kept around the patches to keep them from absorbing any air

–  Liquid Paraffin is also known as mineral oil (remember this ingredient is highly refined and thus safe for use in cosmetics). For these patches, the liquid paraffin acts by retaining moisture in the area by providing a protective layer. This ingredient allows the sticker to block anything from getting into the acne spot and allowing further bacteria or oil to penetrate the skin

– Tetrakis Methane: after a lot of research, I am unable to determine exactly what this ingredient is used for in the formulation. While available on many chemical suppliers websites, there is no set information on the ingredient itself (If you have any knowledge of this ingredient I’d love to learn about what it does)!

So after reviewing this list, you may have a better idea of how this product works. The polymers that make up the patches give them the sticker quality, while the ingredients cellulose gum and liquid paraffin allow the skin to retain moisture while keeping the area protected from being exposed to any further bacteria or oil. So despite not containing any anti-acne ingredients, the ones included in this formula are able to keep the acne spot protected and allows the healing process to begin.

my review

I’ve used quite a few of these patches and have found them to be helpful every time. I typically only use the patches once the acne spot has been there for a day, so more than a bump but less than a full-on white head. Also, for the price point ($5 and available on Amazon) I’d highly recommend keeping these patches in stock for any last minute pimple emergencies. The sticker has stayed on during showers, washing my face, and sleeping, only peeling off when I do it myself. Highly recommend these patches for those who are prone to getting breakouts.
