Key Ingredients

A.D.F. Medical-grade Hydrocolloid Dressing

What it is & why it works  

What it is: The original, cult-favorite hydrocolloid spot patch designed to absorb gunk, flatten angry blemishes, and create a protective seal over active breakouts.
Why it works: These patches utilize A.D.F. hydrocolloid material, which was originally designed for medical wound care. It creates an airtight, moist environment that naturally draws out pus, excess oil, and impurities directly from the pore without squeezing or popping. By acting as a physical barrier, it shields the pimple from external bacteria and prevents you from picking at it, dramatically accelerating the healing process and minimizing the risk of dark post-acne scars.

Trust & Transparency

Is this product cruelty-free?  

Animal testing for cosmetics has been banned in the EU since 2013 and in Korea since 2017, and every product we stock is sold in line with European cosmetics law. Where a brand also holds an independent certification such as Leaping Bunny or PETA, you will find the logo on the pack.

Cruelty-free is not the same as vegan. For formulas without animal-derived ingredients, look for our Vegan tag.

What are the KKUMIDA SIX?  

Six tags that show at a glance what a formula leaves out and how it was checked: Alcohol-Free, Fragrance-Free, Pregnancy-Friendly*, Clean Ingredients, Vegan, Dermatologically-Tested. You will see them on product pages, and you can filter any collection by them.

*Always patch test first. If you are pregnant or breastfeeding, check with your doctor before adding anything new.
What each tag means →

Is everything 100% authentic?  

Yes. We buy only from the brands themselves or their authorised distributors, never from resellers or marketplaces. Every product arrives sealed with its original Korean batch code and ships from our own warehouse in Switzerland or Austria. If anything looks or feels different from what you know, email us a photo and we will make it right.

Where does this fit in my routine?
