Hydrocolloid

You can see it working.

Most spot treatments ask you to take it on faith. A hydrocolloid patch does not. It turns white as it draws fluid and oil up out of a surfaced spot, so the proof is on the patch when you peel it off in the morning.

What is actually happening

A wound-care material, doing what it was built to do.

Hydrocolloid is the same class of material used in wound-care dressings. It absorbs fluid and holds a moist, protected surface. On a surfaced spot that means the mess goes up into the patch instead of sideways into your skin, and the area stays covered while it settles.

The white patch

That white circle is the point, not a flaw.

It is what came out. People message us photos of it, which is not something anyone does about a cream. Three sizes come in every pack, so a nose whitehead and a jawline breakout each get a patch that fits.

Questions people ask about hydrocolloid patches

What is a hydrocolloid patch?

A hydrocolloid patch is a small adhesive dressing made from the same gel-forming material used in wound-care dressings. Placed over a spot that has come to the surface, it absorbs fluid and oil and holds a moist, covered surface underneath while the skin settles.

Why does a hydrocolloid patch turn white?

The white area on a hydrocolloid patch is the fluid it has absorbed. The gel swells as it draws liquid out of the spot, which turns the clear material opaque. It is the patch working, not the patch failing.

Does a hydrocolloid patch work on a pimple under the skin?

Not really. A hydrocolloid patch needs something to absorb, so it suits a whitehead or a spot that has already surfaced. For a sore, solid bump that has not come to a head, a microneedle patch is the one designed for that case. STIK explains the difference at how microneedle patches work.

How long should you wear a hydrocolloid patch?

Most people wear a hydrocolloid patch overnight, or through the day under makeup, and change it once the white area stops spreading. It can be replaced with a fresh one if the spot is still weeping.

Can you wear a hydrocolloid patch under makeup?

Yes. Hydrocolloid patches have a matte finish and thin edges, so foundation can be applied over the top. STIK's Air Dot is the thinnest option in the range for daytime and on-camera wear.
