COSRX Acne Pimple Master Patch (3 pack)

A cheap, reliable hydrocolloid patch for surface whiteheads that will not help deep cystic acne.

The short version

Buy it if
  • People with occasional whiteheads who want a cheap overnight fix
  • Anyone who tends to pick at spots and wants a cover over them
Skip it if
  • Your breakouts are mostly deep, cystic or hormonal
  • You want a medicated patch with an active acne ingredient
  • You need a patch that is truly invisible during the day

What owners like

  • Works well overnight on whiteheads and pimples that have come to a head
  • Stays stuck through the night
  • Thin and fairly discreet, and fine on sensitive skin for many users
  • Low cost for the number of patches

Common complaints

  • Does little for cystic, blind or hormonal pimples with no opening
  • A slight sheen shows in some light, so daytime wear is not invisible
  • One skeptical reviewer found removal irritating and called the claims overstated
  • Patches run out fast during a bad breakout

Based on A retailer product listing with the full ingredient list, three independent beauty blog reviews (one of them negative) and the maker pages of two competing patches..

What it does

Thin, clear hydrocolloid stickers in three sizes that go over a pimple, absorb fluid and cover it, sold here as three packs of 24 patches.

  • Three sizes on each sheet to match the size of the spot
  • Clear, thin patch that some people wear under light makeup
  • Turns white as it absorbs fluid, so it is easy to see when it has worked
  • Covers the spot so it is harder to pick at

A low cost, widely liked pick for surface whiteheads and pimples that have already opened, and for anyone who needs a barrier to stop picking. It has no acne medicine in it and does little for deep, cystic or hormonal bumps, and the patch has a slight sheen in daylight.
