What are the ingredients of COSRX Acne Pimple Master Patch?

These are the only ingredients found in your favorite pimple patch:

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

Key ingredients:

100% A.D.F. Hydrocolloid Dressing

Hydrocolloid dressings have always been used to cover up wounds and cuts. They consist of an adhesive border with a gel-like substance in the middle, which the wound will absorb.

This specific dressing by COSRX was formulated to adhere to excess oil and gunk on the skin. Once taken out, the healing of active acne speeds up leaving no redness and keeps the skin moisturized.

Liquid Paraffin

This emollient is a thin layer that stays on top of the skin to help prevent moisture loss. Made from mineral oil, it secures hydration to maintain skin looking glowing and healthy.

No Harsh Ingredients

This product doesn’t contain harsh ingredients like parabens, sulfates, phthalates, or alcohol. It’s also cruelty-free, vegan, and hypoallergenic.

What are the things to consider when buying a pimple patch?

There are two things to consider when buying a pimple patch: your acne type and the ingredients.

Acne Type

Know that not all acne pimple patches have the same use. That is why a lot of consumers would complain that it doesn’t work for them.

Take note that there are patches that are specifically made for cystic pimples, to help bring the pimple up the skin’s surface so that it would be easier to treat.

There are also patches made for active and inflamed pimple, which contains specific ingredients that will ease the inflammation and remove redness.

Other patches are also made for already popped and dried pimples to help remove excessive gunk from the blemishes.


A wise consumer always checks the ingredients first before buying it. Especially if you have sensitive skin, the ingredients of a beauty product will matter most in your skincare routine. Take note that your anti-acne patch should have nourishing ingredients to make sure that it can do more than just fight pimples and acne. It is also important that it will help your skin soothe and heal gently to prevent scarring and hyperpigmentation once the inflammation goes away.

Snub a product if it contains harsh ingredients like parabens, sulfate, alcohol, and phthalates to avoid irritating your skin.

Does the COSRX Acne Pimple Master Patch actually work?

Yes. COSRX Acne Pimple Master Patch is made from 100% hydrocolloid.

Hydrocolloids are occlusive, waterproof dressings that are generally meant for external wounds. These fancy Korean inspired pimple patches are made to create a matrix over the wound, acting as a scab, and allowing the body to maintain healing fluids and protecting the wound itself.

Hydrocolloids are also effective in maintaining the level of moisture in the skin to help the acne and pimple healing process.

These patches are essential when you have breakouts to protect your skin from further exposure to dirt, bacteria, and dust. Thus, using these would prevent secondary infection of acne, prevent squeezing of pimples with your hands, and definitely works safely and effectively for teens, pregnant women, all age groups, and all skin types.

User reviews from Amazon:

Effective for sensitive, dry skin, and hormonal acne.

My face has transformed from covered with acne, to an occasional pimple that’s soon gone…The way it works- it pulls anything inside the pimple to the surface. Occasionally I have to pop a Whitehead in the morning, as it didn’t completely pull it out. It reduces any swelling or inflammation, leaving the pimple completely flat. The area on the skin may still show a mark (at least on my skin), but it’s easily covered with makeup and the texture of my skin is improved.” -Elissa

Helps removed popped acne and blemishes

These little patches work great for helping (popped or opened) blemishes to disappear within days or even hours – they help reduce scarring and keep me from picking and making the situation worse. After slapping one of these on overnight, a big blemish was emptied of all remaining gunk, and what was a swollen bump became a flat, slightly red spot that disappeared completely by the next day.” -Meems

Leaves pimples flattened overnight

“I have predominantly cystic acne and find that these patches suck a lot of the oil and gunk out of the pore without having to pop the pimple (sometimes you can’t pop them when they’re really deep). When I leave them on overnight they keep the area hydrated while also removing oil and keeping it contained to a small area. When I do pop a pimple and put the patch on top, they work even better. It amazes me how they leave even most cystic pimples flattened by the morning” –CCL


Is it worth the money? Definitely yes!

The COSRX Acne Pimple Master Patch is very effective in shrinking out the pimple on the face, as well as the whiteheads. With just several hours, it can already do wonders plus, it is pain-free to remove without leaving any redness and marks.

Not only that, but it also has nourishing ingredients that help your skin bring back its healthy state.

Though these patches can work slowly for cystic acne since cysts are deeply rooted in the skin and would take time to pop and heal.
