Master Patch Basic [36ea]

COSRX Master Patch Basic, 36-piece pack is the manageable size of the brand's classic hydrocolloid spot patch — enough to get through a few breakout cycles without committing to a bulk box. Each patch is a 12 mm circle of hydrocolloid that sits discreetly on the skin, day or night.

What it actually does

• Deals with a spot the moment it shows up. COSRX positions this as the comfortable answer to breakouts you did not plan for.
• Suits all skin types. The brand attributes that to the quality of the hydrocolloid it uses.
• An alternative to popping. COSRX's point is that covering the blemish clears it faster and without the scarring that squeezing causes.
• Discreet 12 mm round. Blends into the skin comfortably enough for daytime wear, not only bedtime.
• Scored sheet. Cut lines mean you can pick out one patch cleanly.
• 36 patches. A sensible starter count if you have not used hydrocolloid before.

How to use

1. Cleanse and dry the blemish area. Dry skin is the one condition that matters.
2. Lift a patch along the cut line and press it down over the spot.
3. Let it sit and heal — a few hours up to overnight.
4. Peel off and swap for a new one if needed.

Questions

Is 36 enough?

For occasional breakouts, comfortably. If you use patches most weeks, the larger count works out better per patch.

Can I put makeup over a patch?

It is thin and designed to merge with the skin, so light coverage on top is possible. Heavy layering tends to lift the edges — if you want it invisible, wear it on a no-makeup day or overnight.

How long do I leave one on?

COSRX simply says stick it on and let it heal. In practice, a full night is the easiest rhythm; change it when you cleanse.

What is the delivery window?
