Master Patch Basic [90ea]

COSRX Master Patch Basic in the 90-piece pack is the stock-up size of the brand's everyday spot patch. Each one is a 12 mm round of high-quality hydrocolloid, cut to blend into the skin so you can wear it through the day as easily as overnight. COSRX's whole argument is simple: patch instead of pop.

What it actually does

• Covers an unexpected breakout immediately. COSRX designs it to work on any spot, on any skin type.
• Hydrocolloid, 100% of it high quality. That is the brand's claim for the material, and it is what lets the patch suit all skin types.
• Keeps your hands off. Sticking one on instead of squeezing is how COSRX frames resolving a pimple quickly without leaving a scar.
• 12 mm round, day or night. Small enough to disappear against skin, comfortable enough to leave on under daylight.
• Cut lines for easy handling. The sheet is scored so you can lift a single patch without peeling up its neighbours.
• 90 patches per pack. The size to buy if you reach for these weekly rather than occasionally.

How to use

1. Wash your face, then dry the spot fully. Any moisture and the patch slides off.
2. Press one on gently over the centre of the blemish.
3. Leave it to heal. Several hours at minimum; overnight is the easy habit.
4. Remove and reassess. Apply a fresh patch if the spot still needs covering.

Questions

Should I buy 90 or a smaller pack?

Take the 90-piece box if breakouts are a regular part of your month and you want patches in the drawer, the handbag and the travel kit. A smaller count makes more sense if you only need them now and then.

Can I wear one out of the house?

Yes — the 12 mm round is made to sit flat and blend naturally, which is why COSRX rates it for day as well as night wear.

Does it work on every type of spot?

COSRX describes it as working for any acne on any skin. It is most at home on a raised, surface-level blemish; deep cystic bumps are a different problem and worth a dermatologist's view.

How long will my order take, and how do I pay?
