A thin, discreet dot that you stick on a spot in the evening and find turned white on waking. COSRX's Master Patch brings together 24 hydrocolloid patches in three diameters in one resealable sachet, to cover a small whitehead as well as a larger spot.
A hydrocolloid pimple patch, with no added active
Hydrocolloid is a material that swells on contact with liquids. Placed on an already formed spot with a white head, it absorbs part of what comes out and turns white as it fills up. At the same time, it acts as a shield against friction, make-up, dust and above all fingers: a spot that is not picked leaves fewer visible marks.
This patch contains no salicylic acid, no tea tree oil and no fragrance. It does not act on the cause of spots and does not replace a suitable routine: it is a physical protection, simple and silent, that mainly helps you leave the area alone.
How to use
- Cleanse the area and dry it thoroughly: the patch sticks poorly to damp skin or skin covered in cream.
- Choose a size that extends slightly beyond the spot, peel off the patch without touching the adhesive side and press for a few seconds.
- Leave it in place for several hours, ideally overnight, then remove it once it has turned white and opaque.
- Apply your skincare around the patch, never underneath.
Reseal the sachet well after each use to keep the remaining patches clean.
Which skin is it for?
They suit all skin types, including sensitive skin, since they contain no active. They are most useful on a spot with a white head that has come to a head. On a red, deep spot with no head, they mainly serve as a barrier so you do not touch it. Do not apply them to an open, infected wound, and ask a dermatologist for advice if spots are numerous, painful or persistent. For everyday skin texture, see the even complexion and pores selection.

Frequently asked questions
How long should I keep a patch on?
At least several hours. Night-time remains the most convenient moment: you remove it on waking, once it has turned white.
Can I wear it during the day?
Yes. Thin and discreet, it goes unnoticed from a few steps away and can take a thin layer of make-up. Just avoid rubbing the area.
Does it work on spots with no head?
Less well. The patch absorbs what comes out of the spot; with no head, there is almost nothing to capture. It still protects the area from your fingers.
Can I reuse a patch?
No. A patch that has been removed has lost its adhesion and holds what it has absorbed: throw it away and take a new one.
Which size should I choose?
The smallest suits isolated whiteheads, the medium one classic spots, and the largest wider spots or two spots close together.
A simple reflex to keep in your wash bag, to leave a spot alone rather than touch it. Find the other essentials in the Korean skincare range.
