Pimple patches are one of the simplest skincare products around. Here's what they do and how to get the most out of them.
What hydrocolloid is
Hydrocolloid is a soft, gel-forming material. Stuck over a spot, it creates a thin, protective cover that sits flat against your skin.
What happens under the patch
Hydrocolloid absorbs fluid from the surface of a blemish that has come to a head, which is why the patch turns white and opaque after a few hours. That's the gel layer filling up.
The patch also covers the spot, so makeup, dirt and fingers stay off it, and it can look flatter and less noticeable when you peel it away.
The underrated benefit
You physically cannot pick at a blemish through a patch. For a lot of people this is the real value. A patch is a barrier between your skin and your own hands.
When they work, and when they don't
Patches work best on surfaced blemishes: whiteheads, spots that have come to a head, anything with fluid to absorb.
They do very little for deep bumps under the skin, blackheads, or general congestion. There's nothing at the surface to absorb. If you put one on a deep bump, you'll peel off a clear patch in the morning and wonder what went wrong. Nothing did, it was the wrong tool.
How to use them properly
- Clean, dry skin. Patches won't stick to anything oily. Skip serum and moisturizer on that exact spot.
- Choose a spot the patch covers fully, with a small margin around it.
- Press down for a few seconds so the edges seal.
- Leave it six hours minimum, or overnight. Pulling it off after an hour does nothing.
- Peel gently and don't reuse it.
Can you wear them during the day?
Yes. They're thin and discreet. Apply makeup over the patch, not under it. Overnight tends to work better simply because you leave them on longer.
Are they enough on their own?
They're for individual surface spots, not an acne routine. Don't use them on open wounds. If you're getting frequent, persistent or painful breakouts, see a dermatologist, who can recommend options no patch can replace.
Our hydrocolloid acne patches come 72 to a pack, which is enough to keep some by the bed and some in a bag.
