Hydrocolloid pimple patches are small, thin stickers that cover a spot. The hydrocolloid material absorbs excess fluid and keeps the spot covered, which also stops you touching or picking it. They're simple to use, but a few small details make a big difference to how well they stick and work.
Which spots are patches best for?
Hydrocolloid patches work best on spots that have come to a head or are already open, because that's when there is fluid for the patch to absorb. They also protect a spot from fingers, make-up brushes and pillowcases. They're less effective on deep, painful lumps under the skin. If you have persistent or severe acne, speak to a pharmacist, GP or dermatologist.
Step 1: Cleanse
Wash the area with a gentle cleanser and water to remove oil, make-up and sunscreen. Wash your hands too.
Step 2: Dry completely
Pat the skin completely dry with a clean towel. This is the most important step, because patches don't stick well to damp or oily skin. Wait a minute after any toner or serum, and don't apply heavy creams under the patch.
Step 3: Choose the right size
Pick a patch that covers the whole spot with a little margin around it. Cavon patches come in five sizes and three shapes — 8, 10 and 12 mm dots, a contoured cheek patch and an XL patch for the forehead or chin. See our patch size guide.
Step 4: Apply
Peel the patch from the sheet without touching the sticky side more than you need to. Place it centrally over the spot and press gently for a few seconds so the edges seal against your skin.
Step 5: Leave it on
Wear it during the day or overnight. As the hydrocolloid absorbs fluid, the patch may turn white or cloudy. See how long to leave a patch on.
Step 6: Remove and replace
Peel the patch off slowly, starting from one edge. Removing it after washing your face, while the skin is slightly damp, makes this easier. If the spot still has fluid, cleanse, dry and apply a fresh patch. Patches are single-use, so never reapply one.
Common mistakes
- Applying to damp or oily skin, so the patch slides off.
- Using a patch that's too small, so the edges lift.
- Putting moisturiser or oil under the patch.
- Squeezing the spot first. Let the patch do the work instead.
- Using a patch on broken, infected or irritated skin.
Safety: For external use only. Don't use on infected spots. If you notice a rash, irritation or signs of infection, stop using the patches and consult your doctor.
