Key Ingredients

EGF (sh-Oligopeptide-1), bFGF (sh-Polypeptide-1), Guaiazulene

What it is & why it works  

What it is: An intensely concentrated anti-aging night serum formulated with dual peptides (EGF and bFGF) to delay the signs of aging and repair the skin at a cellular level.
Why it works: The watery texture allows the highly active ingredients to penetrate deep into the skin instantly. EGF (Epidermal Growth Factor) and bFGF (Fibroblast Growth Factor) work synergistically to stimulate collagen and elastin production, which naturally decline as we age. Enriched with Guaiazulene to soothe the skin overnight, this blue drop effectively diminishes fine lines, improves overall skin texture, and restores a youthful, bouncy resilience while you sleep.

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
Cleanser → Toner → Serum or ampoule → Eye cream → Moisturiser → SPF, every day, winter included

Evening
Oil cleanser → Water cleanser → Toner → Mask or device, 2 to 3 times a week → Serum or ampoule → Eye cream → Moisturiser

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.
