Mighty Patch vs COSRX is the pimple-patch argument that doesn't need to be an argument. Same material, different thickness, different price, different pillow behaviour. Pick the one that matches how you sleep and whether you want the sticker seen.
If you want a one-line answer: COSRX for daytime and value, Mighty Patch Original for overnight and after you've picked. Everything below is that sentence with receipts.
The short comparison
| | COSRX Acne Pimple Master | Mighty Patch Original | |---|---|---| | UK price | ~£6 for 24 | ~£8 for 24 | | Thickness | Thin, cling-film | Thicker cushion | | Sizes | Small, medium, large | Mostly one medium | | Best worn | Day or night | Night | | Stick on a pillow | Good if skin is dry | Better | | After popping | Fine | Better lid | | Under makeup | Yes | Original, not really |
Mighty Patch also sells Surface and Invisible+ for daytime. Those close the thickness gap and reopen the price gap. If you're buying those, you're no longer comparing like-for-like with a £6 COSRX pouch.
Price in the UK
COSRX is cheaper. Superdrug and Cult Beauty sit around £5.99 for the 24-patch Master pouch. Mighty Patch Original is about £8 at Boots and on the Hero UK site, sometimes less on offer. Invisible+ is around £11, Surface around £15.
Per patch, COSRX is the clear win. Per night of sleep if you keep losing thin patches, Mighty Patch can be cheaper because you use one instead of three. That's the only honest way the American one "saves money".
Don't buy a Mighty Patch bundle of every variant to "test the range". Pick Original or pick COSRX. The UK round-up has the rest of the shelf if you want chemist options like Dots for Spots.
Stick
Both stick if the skin is clean and dry. Both fail if you put them on damp skin or over moisturiser. That's user error, not a brand difference.
Mighty Patch Original is clingier. The thicker pad and stronger adhesive survive a face-down sleeper and a bit of tossing. COSRX will stay on a still sleeper and often won't survive a humid night on your side.
If your complaint about COSRX is "they fall off", try actually drying your face for two minutes, then try Mighty Patch if they still vanish. Don't jump straight to a £15 Surface pack to solve a wet-skin problem.
Thickness
This is the real difference.
COSRX is a film. You can forget it's there, which is ideal at a desk and slightly dangerous if you're a picker: out of sight, fingers wander back. Mighty Patch Original is a noticeable bump. You can feel it. That's annoying in daylight and useful at night, because it reminds you not to touch.
Thicker also means a more dramatic white centre by morning. People read that as "it worked harder". It absorbed more visibly. On a juicy whitehead both brands go cloudy. On a barely-there spot, Mighty Patch still looks like it did something because there's more gel to turn opaque.
Whiteheads vs after popping
Whiteheads with a head: both work. Hydrocolloid doesn't care about the logo. COSRX is enough. Save the thicker patch for when you want overnight insurance.
After popping: Mighty Patch Original is the better tool. You've made a small open wound and you need a lid that doesn't peel at 3am. The thicker hydrocolloid soaks the leftover fluid and keeps you from going back in. COSRX can do this; it's just easier to knock off a tender, damp spot.
Neither brand makes popping a good idea. If you're using patches as permission to squeeze, read why you shouldn't and then use the patch as damage control only.
Closed, blind, cystic: neither. Depth doesn't care about thickness. There's a separate page for cysts.
Who should buy which
Buy COSRX if: you want one pouch that covers tiny chin spots and larger forehead ones, you wear patches during the day, and £6 is the correct amount of money for a sticker.
Buy Mighty Patch Original if: you sleep on your face, you pick, or you specifically want that thicker overnight feel. Accept that you'll look like you have a small device on your cheek.
Buy both if: you already know you use thin ones at work and thick ones in bed. That's not indecisive. That's matching the tool to the hours.
Buy neither if: your spots never come to a head. Spend the money on a salicylic acid product instead.
The longer COSRX-only take is here. Mighty Patch doesn't need its own love letter; it's a good thick patch at a Boots price.
What I wouldn't do
I wouldn't treat Mighty Patch as "medical grade" and COSRX as "the cheap one". Both are hydrocolloid dressings cut for faces. I wouldn't buy Invisible+ and Surface and Original to cover every scenario. I wouldn't pay shipping from the US. Boots and Superdrug exist.
And I wouldn't use either one as your acne routine. A patch is for the spot that's already here. Prevention is still cleanser, a BHA, and leaving your face alone.
FAQs
Is Mighty Patch better than COSRX?
It's thicker and usually stickier overnight. COSRX is cheaper, thinner and has more sizes. Better depends on whether you want a daytime film or a nighttime cushion.
Which is cheaper in the UK, Mighty Patch or COSRX?
COSRX, usually about £6 versus about £8 for Mighty Patch Original. The gap widens if you buy Mighty Patch Surface or Invisible+.
Which pimple patch stays on better overnight?
Mighty Patch Original, for most people who move in their sleep. COSRX stays on if your skin is dry and you don't sleep on that side.
Can I use COSRX after popping a pimple?
Yes. Mighty Patch Original is a more reliable lid on a wet spot, but COSRX still beats leaving it open. Don't pop it next time.
Do I need Mighty Patch Surface if I already have COSRX?
No. Surface is Hero's thin daytime patch. That's the job COSRX already does for less money.
