- Thin enough to wear under makeup without a visible ridge
- Keeps hands and grime off the blemish while it settles

## How it works

A patch worn in daylight has a second job: it has to disappear. This is the thin, matte cut in COSRX's Master Patch range, made to sit under makeup rather than visibly on top of the skin. It goes on once the morning routine has absorbed and before makeup, on skin that is completely dry. The dressing still works the way any hydrocolloid does, taking up what the spot gives off while keeping hands off it. One patch per spot, replaced after several hours.

## How to use

1. Press one Master Patch Clear Fit onto clean, dry skin once your morning routine has absorbed.
2. Press it flat from the middle out, then put makeup over the top of it if you want to.
3. It goes on before makeup and comes off with it; skincare goes underneath, never over.
4. Replace it after several hours. Do not put one over sunscreen or moisturizer that is still wet; it will not hold.

## FAQ

### What is different about the Clear Fit compared to other Master Patch options?

This patch shares the same seven-ingredient material, cellulose gum, styrene isoprene styrene block copolymer, polyisobutylene, petroleum resin, liquid paraffin and tetrakis methane, as the Original Fit, but polyurethane film is named first here rather than fifth. That ordering points to a thinner, more film-forward construction, matching its ultra-thin, near-transparent finish. It ships eighteen to a box, still working as a plain absorbent dressing.

### Will this thinner patch still work on skin that's easily irritated?

Fragrance, essential oil, denatured alcohol, silicone, parabens, sulfate surfactants, mineral oil and added colourant are all absent from the ingredient list, exactly as with the rest of the line. The film relies on petroleum resin, liquid paraffin and polyurethane film for its structure rather than any treatment ingredient, so there's nothing added here beyond the dressing structure itself. Adhesive sensitivity, not an active ingredient, is the main thing to watch for.

### Does the thinner film absorb fluid as well as a thicker patch?

Cellulose gum is the same absorbent ingredient doing the work here as in the thicker Master Patch versions, drawing fluid from the spot and turning visibly white or cloudy as it fills. A thinner film changes how visible the patch is under makeup, not how the absorption itself happens. Watching for that color change, rather than the patch's thickness, is still the sign to replace it.

### Can I wear makeup over this patch during the day?

The near-transparent, matte film is built to sit under makeup, since nothing in the seven-ingredient list is a treatment serum that would need to absorb into skin first. Applying makeup once the patch is pressed down firmly at the edges is the straightforward order here, rather than trying to work makeup underneath the film itself.

### How can I tell my Clear Fit patches are genuine COSRX?

The EAN 8809598455733 on the box matches directly against your own unit as a first check. Beyond that, COSRX verifies units itself: the batch number and expiration date printed on your box can be entered on the verification page at cosrx.com. Checking those two codes against your own packaging is the actual verification, not the barcode alone.
