  • these patches are a game changer—stick all night even when i move around, and seriously draw out the gunk fast. my spot looks way less red by morning. only thing is they’re kinda obvious when you’re out and about, but at home nobody cares lol

COSRX Acne Pimple Master Patch is a pack of 24 thin hydrocolloid spot patches in three sizes. Placed over a spot, a patch absorbs fluid, keeps the area covered and moist, and stops you touching or picking it.

What it does

Hydrocolloid is a gel-forming material also used in dressings. On a spot that has come to a head, it draws up fluid and gradually turns white as it fills, which is your cue to change it. The thin cover also keeps out fingers, dirt and makeup while the spot settles.

Why we chose it

It is the simplest way to leave a spot alone: there are no active ingredients, so nothing drying goes on the skin around it. A pack is small enough for a wash bag or handbag.

Best for

  • Spots with a visible white head
  • Anyone who tends to pick at spots
  • Overnight wear, or discreet daytime cover
  • Travel and gym bags

Not ideal if

  • Your spot is deep, sore and has no head: patches work best on surface spots
  • You want an active treatment: the patches contain no salicylic acid, tea tree or other actives
  • You react to adhesives or mineral oil: the base contains liquid paraffin and adhesive polymers

Key ingredients

  • Cellulose gum: the hydrocolloid that absorbs fluid
  • Styrene isoprene styrene block copolymer, polyisobutylene and petroleum resin: the adhesive base
  • Polyurethane film: the thin protective outer layer
  • Liquid paraffin (mineral oil): part of the patch base

Texture and finish

Thin, flexible, see-through patches that sit flat on the skin.

Where it goes in your routine

Cleanse and dry the area first, then apply the patch before any other skincare so it sticks well. Choose a patch a little bigger than the spot and press it down gently. Leave it on for several hours or overnight, and replace it daily, or sooner once it turns white, as the pouch directs. Continue your skincare around it.

  • Cleanse the area and pat it completely dry. The pouch says to apply it to clean, dry skin before any other skincare.
  • Choose a patch a little bigger than the spot, as COSRX recommend.
  • Peel it off the film and press it gently in place.
  • Apply the rest of your skincare around it, not under it.
  • Replace it daily, or sooner once it turns white, as the pouch directs. Use each patch once.
  • Keep unused patches sealed in their pouch, and stop using them if a rash appears.

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

Good to know

  • Contains liquid paraffin (mineral oil)
  • No active ingredients, no fragrance and no acids
  • Single use: use each patch once
  • Pouch cautions: For external use only. Store unused patches in the plastic pouch and keep the pouch sealed to maintain freshness. Stop using and ask a doctor if rash occurs. Store in a cool place away from direct sunlight.

What kind of spot does it work best on?

Surface spots that have come to a head. The patch needs fluid to absorb, so on a deep, sore spot with no head it mostly just covers the area.

Is it an acne treatment?

No. There are no actives such as salicylic acid or tea tree in it. It works physically: it covers the spot, absorbs fluid and stops you touching or picking while the spot settles.

Why does the patch turn white?

Hydrocolloid forms a soft gel as it absorbs fluid, and that gel looks white. When the patch has turned white, replace it with a fresh one, as the pouch directs.

Can I wear it during the day?

Yes. The patches are thin and see-through, so they are fairly discreet. Put the patch on first, on clean, dry skin, so it sticks well, and apply other products around it.

Is it suitable for sensitive skin?

Usually, as there is no fragrance and no active ingredient. The base contains adhesive polymers and liquid paraffin (mineral oil), so if you react to plasters or adhesives, try one patch first. The pouch says to stop using it and ask a doctor if a rash occurs.

What sizes are in the pack?

COSRX list 24 patches in three sizes: 10 small, 5 medium and 9 large. Pick the size that just covers the spot with a little margin.
