What does Pimple Patches do?#

Pimple patches are thin, adhesive stickers that sit over an individual blemish. They create a protective, moisture-retaining cover that helps the spot look less noticeable and keeps you from touching or picking it.

  • Creates a protective barrier over individual blemishes to help them look less noticeable
  • Provides a protective, moisture-retaining cover over the blemish
  • Prevents picking and touching, which can worsen the appearance of blemishes
  • Sticks securely for either overnight or daytime wear

How it works

A pimple patch works by forming a soft, moisture-retaining seal over the spot. The patch's soft cover protects it from outside contact and the temptation to touch, which helps the blemish look less red and less noticeable while it settles.

How to use Pimple Patches#

  • It goes on last, straight onto clean dry skin, with nothing underneath it — a serum, cream or oil on the spot is the usual reason a patch slides off.
  • One patch, one spot. Choose a size bigger than the blemish so the edge sits on unmarked skin all the way round, and press the whole edge down.
  • Overnight or through the day both work. Follow the timing on the pack.
  • Change it once a day, or sooner once the middle has turned white. The white circle is the patch itself changing colour — it is not anything pulled out of the spot.
  • Take it off slowly, drawing it back flat along the skin rather than straight up. If it is stuck, take it off in the shower.
  • It suits a spot that has already opened at the surface. A deep bump under the skin gives it little to work on.
  • It is a spot-by-spot step rather than a daily one — there is nothing for it to do on a day with no blemish.
  • If the skin under or around the patch stings, itches, or comes up red and flaky rather than settling, stop using them; some people react to the sticky layer.

Do not apply to broken, bleeding, or open skin. For use on intact blemishes only. If you experience redness or itching around the patch edges, you may be sensitive to the adhesive — discontinue use.
