What can it help with?

Hydrocolloid patches absorb fluid from an open pimple and cover it, which can help protect the spot from more picking. A pimple patch is a tiny wound dressing with one tightly scoped assignment.1

That makes a patch most useful on a surface spot that has opened and is draining, not as a way to clear clogged pores or stop new breakouts. Acne does not take attendance from one sticker.1

How do you use it?

  1. 1Wash the affected area, then dry it thoroughly; patches do not stick as well to wet skin.
  2. 2Place the patch over the spot.
  3. 3Leave it on for the time printed on the COSRX packet. General pimple patch directions often call for a few hours, and some patches are designed for overnight wear. The packet is the boss here; a sticker is a poor negotiator.
  4. 4Remove it at the recommended time. The spot may look smaller and less inflamed afterward.

What results should you expect?

A patch may make one blemish look smaller and less inflamed after removal, but it is not an acne treatment plan. Evidence for hydrocolloid use on acne is early, with only a few studies reported.2

What if your skin is sensitive?

Patch adhesive can aggravate the skin around a spot if you are sensitive or allergic to adhesives. Some pimple patches also contain ingredients such as salicylic acid or tea tree oil, which can irritate already irritated skin. Avoid a patch that has caused a reaction, and remove it if the surrounding skin becomes irritated.1

How long should you leave a COSRX pimple patch on?

Follow the wear time on the COSRX packet. Pimple patches generally need a few hours, but the recommended time depends on the specific product.1

Can you wear COSRX pimple patches overnight?

Many pimple patches are made for overnight wear. Check the COSRX packet to see whether that applies to your patch, then remove it at the stated time.1

Do COSRX pimple patches work on blind pimples?

Blind pimples sit under the skin, and clinical guidance is mixed on whether patches help them. A patch can help keep fingers away, but do not count on a hydrocolloid patch to flatten a deep, closed bump. A warm, damp cloth held on the area for five to 10 minutes several times a day is another at home option; do not squeeze the spot.13

When should you get help?

Contact a healthcare provider if a blind pimple is very painful, several appear, or they keep coming back. Get medical advice if a deep, painful pimple does not improve with at home care or more deep, painful pimples develop.45
