What it is & why it works  

What it is: A highly concentrated, clinical-grade vegan serum packed with 20% Niacinamide to target stubborn hyperpigmentation, uneven texture, and enlarged pores.
Why it works: At a powerful 20% concentration, Niacinamide works deep within the skin to halt melanin transfer, effectively fading dark spots and post-acne marks. The addition of Zinc PCA helps to regulate sebum production and physically tighten the appearance of pores, while Arbutin provides an extra brightening boost. Despite its high potency, this clean formula is balanced with hydrating Panthenol to ensure oily and combination skin remains calm, clear, and flawlessly radiant without irritation.

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?  

For skincare, layer from the thinnest texture to the thickest.

Morning

Use strong acids (AHA, BHA, PHA, peels) and retinoids on different nights, and add one new active at a time. For hair, body and makeup, follow the directions on the pack.
