What does a hydrocolloid patch actually do?

Hydrocolloid is a gel used in wound dressings. A pimple patch absorbs fluid such as pus and oil while covering the spot against further picking. Covering one spot does not prevent the next breakout, so the sticker has a smaller job than its place in the skincare aisle suggests. Think of a patch as care for an individual blemish, not a replacement for acne treatment.12

How do you apply the patches?

  1. 1Wash the affected area gently. Do not scrub the spot or squeeze it to prepare it for a patch.
  2. 2Dry the area thoroughly. Patch adhesive does not stick as well to wet skin.
  3. 3Apply the patch directly over the blemish, following the directions on your exact Starface pack.
  4. 4Leave the patch on for the time stated on the pack. Many pimple patches are intended for several hours or overnight, but use your product's own timing.
  5. 5Remove the patch when the stated wear time is complete.

What should you expect after wearing one?

After removing a hydrocolloid patch, the blemish may look smaller and less inflamed. There is some evidence of benefit on closed pimples, but patches work less well there than on spots releasing fluid. Blackheads and deeper whiteheads are poor targets. A patch can protect the surface of a deep pimple without resolving the acne underneath.13

Should you pop a pimple before applying a patch?

No. Popping can push pus, bacteria and inflammation deeper into the skin, increasing the risk of marks and scars. Bacteria from your hands can also enter broken skin and cause infection. A hydrocolloid patch can help protect a spot that has already opened; that is not a reason to open it deliberately.4

What if you have sensitive skin?

Patch adhesive can aggravate skin if you are sensitive or allergic to it. Some patches also contain acne ingredients that irritate an already irritated area, so check the exact ingredient list rather than assuming all patches have the same formula. Stop using a patch if the affected area becomes irritated or excessively dry. An adhesive allergy is a reason to avoid adhesive patches.12

What if you keep needing patches?

Recurring acne needs treatment that addresses new breakouts, not just coverage for existing ones. Acne medication is generally applied in a thin layer across the acne prone area rather than only to visible spots. Treating only the pimples you can see leaves the routine permanently working through yesterday's inbox. For mild adult acne, options include benzoyl peroxide for small pimples and salicylic acid for blackheads and whiteheads. Follow the medication's directions; these are separate treatments, not instructions to put medication beneath a patch. Effective acne medication usually produces fewer breakouts in 4 to 8 weeks, with clearing taking around 16 weeks. If you are pregnant or trying to become pregnant, consult a dermatologist before starting acne treatment yourself.5

When should you get help instead of adding another patch?

See a dermatologist for a deep, painful pimple that does not go away, or for multiple deep, painful pimples. Nodules and cysts develop below the skin's surface and need more than a surface dressing. Speak to a doctor if acne is worsening, causing scars or affecting your mental health. A pharmacist can help you choose treatment for mild acne.23
