Things to Consider When Choosing a Pimple Patch:

Things to Consider

Acne Type

Some pimple patches specifically target active and inflamed pimples. 

They would contain specific ingredients that will soothe inflammation and hide redness.

Other patches are better for already popped and dried pimples. They function more to take out the remaining gunk from the blemish.

Finally, some patches work best for cystic pimples. They help bring the pimple up to the surface so that it’s easier to treat.


It’s best to check the ingredient list to find out if your anti-acne patch can do more than just fight pimples. 

Nourishing ingredients can help soothe your skin as it heals. They help avoid scarring and hyperpigmentation once the pimple goes away.

Also, make sure that the ingredient list doesn’t contain anything that might irritate your skin further. Toss it if you find any harsh chemicals.


COSRX just means “cosmetics” plus “RX” (prescription). It’s a brand that prides itself on solving common skin issues through medically-formulated products. This has made it one of the most famous Korean beauty brands today.

The brand’s philosophy puts customers at the center by listening to their specific skin concerns. By creating products that address these concerns, the brand empowers consumers to be more confident.

It also believes in minimalism. Its formulas are certified clean and natural. Product packaging is also designed with simple visuals and designs.


COSRX Acne Pimple Master Patch

Pimple emergencies are now easier to solve with this wonder product from COSRX.

Overall Rating: 5 out of 5 Stars

These pimple patches are a real lifesaver, especially for those with acne-prone skin. 

Each pimple patch effectively takes out the gunk and oil from your pimples to help them heal faster.

Though it doesn’t contain any of the typical anti-acne ingredients, it still does a great job at fighting acne. 

The sticky side that adheres to your skin is actually a hydrocolloid dressing that heals as it moisturizes.

It works best on pimples that are already ripe or dried. If you leave the pimple patches on overnight, you can surely expect the pimple to be gone by morning. 

You’ll notice that the patch will turn white once it has absorbed all the oil from your pimple. That’s when you can peel it off. 

It’ll even be satisfying to see all the gunk it was able to take out!

For cystic acne or pimples that haven’t come to a head yet, you can still use it. It will help stop you from picking on the blemishes and speed up the drying process.

Also, since it sticks so well to the skin and is waterproof, you can even wear makeup over it. It’ll make your pimple look flatter so that it’s easier to conceal.

The best part is that the patches come in three different sizes so you can pick whichever fits the size of the blemish.

We give this 5 stars out of 5. There are hardly any downsides except for maybe the fact that you’ll eventually run out of them!

Key Ingredients and Their Benefits on Your Skin

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 designed to adhere to oil and gunk on the skin. Once taken out, the healing of active acne speeds up.

Liquid Paraffin

This emollient is a thin layer that stays on top of the skin to prevent moisture loss. 

Made from mineral oil, it locks in hydration to keep skin looking healthy.

No Harsh Ingredients

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


The patches are packed inside a sterilized, resealable aluminum pouch. 

Inside the pouch is one clear plastic sheet where all 24 pimple patches are attached to.


Like any other hydrocolloid dressings, the pimple patches are adhesive on one side and waterproof on the other. 

The adhesive side contains healing ingredients.

They’re translucent white in color and round in shape. They also come in three sizes.


These pimple patches are formulated without fragrance so they have no scent.


After cleansing and toning, apply the patch on top of any active pimples. Choose from the three different sizes, depending on the size of the blemish. 

You can leave it on overnight or until you notice that the patch has turned white (meaning it has absorbed oil from the blemish).

User Reviews

User Reviews

Many users can vouch for this product’s fast-acting abilities. They usually leave it on overnight and then wake up to clearer skin.

A lot of them even like to buy this product in bulk since it’s almost always sold out at stores and beauty websites.

The different sizes of the patches are also a star characteristic. Users can choose a patch size based on the severity of their pimple.


Heals Pimples While Looking Invisible

One user notices that the patch really does absorb all the oil from her pimple. When she peels the patch off in the morning, she can see all the gunk on the sticky side of the patch.

She also likes that it’s barely noticeable so she can wear it even during the daytime when she leaves the house.

“I put them on whiteheads overnight after washing my face. By morning, the pus is on the sticker then I wash my face and let the pimple breathe to heal. I even go out with these on because they look invisible.”

Helps Avoid Scarring

Another user in the medical field says she loves this product so much. She compares it to the hydrocolloid patches she uses on her patients after surgery.

She says that it’s helped her ditch her bad habit of picking at her skin since it covers the blemish well. She has less scarring now since she’s less tempted to pop her pimples.

For more severe pimples though, it took 2 more patches to completely flatten inflammation for her. Healing time still depends on the severity of the blemish.

“I have a habit of pricking pimples and it leaves scars. When I had the urge to squeeze them, I placed one patch. It took me 2 more patches before it healed.”

Speeds Up Healing

The pimple patches also worked well for another user. It just took a little bit longer for her other pimples that didn’t come to a head yet.

She still plans to keep using the patches since they really speed up the healing process of her pimples.

“They’re effective on pimples that have come to a head or been extracted. Overnight, they reduce in size. They’re flat by morning. My only complaint is that they take longer to work on pimples that haven’t come to a head.”

ZitSticka Killa Kit

Cystic acne is much trickier to solve but this product will help keep it under control. It has Salicylic acid to soothe and unclog red, painful cysts.

The patches are 16 in total and divided into two kinds: Killa and Cleana. You should use the Killa patches first to prep the skin. The Cleana patches are to be used after to exfoliate and unclog the pores. 

The patches also look unique since they have dissolvable microneedles on top of the medicated adhesive. These microneedles help penetrate cystic pimples better and bring them to the surface faster.

Conclusion - Should I Buy the COSRX Acne Pimple Master Patch?
