Review: CosRX Acne Pimple Master Patch

cosrx acne pimple master patch

Most of us have that day when a pimple just randomly pops on our face, big and ripe and daring to be picked on. There are some popular last-minute solutions, most of which I find less than satisfactory: rapid treatment creams (ineffective and don’t work as fast as they advertise), popping (often resulting in scars, making the blemish more obvious), corticosteroid injection (never tried, too expensive) and make-up (doesn’t always cover pimples well, especially ones with raised bumps).

That was why the idea of spot patches sounded promising to me – something that both covers up the unsightly acne and heals blemishes? Sign me up!

CosRX Acne Pimple Master Patch is perhaps the most popular acne patch / hydrocolloid dressing in the market today. Hailing from a well-known Korean beauty and skincare brand, the patch claims to protect “wounded or troubled area from getting worse and [maintain] humidity of skin to prevent further breakouts”. Each pack contains 24 patches in three sizes (7mm, 10mm and 12mm diameters). The retail price varies depending on where you buy it, but generally in Australia you can get it for under $10 in Asian beauty stores or online shops.

So how effective is it?

The patch covers blemishes well – it doesn’t come off as invisible, nor does it go well under makeup, but it’s good enough to conceal exposed pimples. The patches also help prevent picking. After a full day out – or around eight hours – the patch turns white from absorbing excess sebum. Sometimes when I pull the patch out, the pus from the whitehead is absorbed out as well – which is disgusting, but also satisfying.

That being said, the patch doesn’t do much for closed comedones, blackheads, blind pimples and cystic acne, apart from preventing you from touching the problematic spots. If your pimples have come to a head, the patch will be a great help – but its use is pretty much limited to this (familiar) situation.

Personally, I also find the biggest patch size (the 12mm) is way too big, considering my average size of whiteheads.

Would I buy this again? Yes – CosRX Acne Pimple Master Patch is a great last-minute spot solution that does what it says in the package with an affordable price.
