What does a pimple patch actually do?
Hydrocolloid is a dressing material that absorbs fluid and forms a protective gel. The covering keeps fingers away and creates a moist environment that supports healing. Hydrocolloid patches are wound dressings in a small format, even when the packaging gives them a more glamorous career.23
The evidence for treating acne with hydrocolloid is promising but still limited. Small acne trials have found improvements in redness, size and texture; one found reduced inflammation from day three to day seven. Treat those findings as a reason to try a patch on a suitable spot, not a timetable for your Starface patch.2
Which spots are worth patching?
An open spot releasing fluid is the best match. Closed surface pimples sometimes become smaller or less red, but patches work less well on them. Blackheads and deeper whiteheads are poor targets. Do not pop a pimple to make it ready for a patch.1
How should you use it?
- 1Wash the affected area before applying the patch. If the spot has already opened, clean away any fluid gently.
- 2Dry the skin thoroughly. The adhesive sticks less well to wet skin.
- 3Apply the patch directly over the spot and follow the wear time printed on your specific pack. Patches generally need several hours; many are intended for overnight use.
- 4Remove the patch at the instructed time. The spot may look smaller and less inflamed.
What if your skin is sensitive?
Plain hydrocolloid patches are an option if added acne medicines irritate your skin. Check the actual pack rather than assuming every patch has the same formula. Adhesive itself can aggravate skin if you are sensitive or allergic to it. Stop using a patch if it irritates the surrounding skin.13
Will it work on a deep, painful pimple?
A patch can protect the area and discourage picking, but a deep lump needs more than fluid absorption at the surface. Do not squeeze it: that increases the risk of infection, discoloration and scarring. Try a clean, warm, damp washcloth for 10 to 15 minutes, three times daily, to help bring the pimple closer to the surface. Use a clean cloth each time.4
See a dermatologist if a deep, painful spot does not go away with home care or you develop several. Stronger medicines or an injection are options a dermatologist can assess. If you keep getting several pimples each week, ask about ongoing acne treatment rather than relying on patches.34
Patches do not prevent new acne, which is a smaller job description than the marketing department would prefer. Acne treatments such as adapalene, salicylic acid and benzoyl peroxide address processes that lead to breakouts; a patch is an extra tool for an individual spot.1
