It was never your skin. The cream just couldn't get in.
Melanin-rich skin has a denser barrier — and most creams are too heavy to pass through it. So they sit on top and do nothing. Rejen was built for it: a Korean PDRN formula small enough to actually get in.
Stuck on the surface as a greasy film. By morning, it's on your pillowcase — nothing reaches where lines form.
Low-weight PDRN slips past the denser barrier, down to where lines and hollows form. Your skin drinks it up — no film, no white cast.
01
It gets in
Low-weight PDRN is cut into smaller fragments, so it slips past the denser barrier of melanin-rich skin instead of sitting on top.
02
It plumps & repairs
10% Volufiline and salmon PDRN go to work where hollows and lines form — no stinging like retinol, no peeling like acids.
03
Your skin shows it
Glowing in week 1. Lines look softer by week 3. Fuller hollows and firmer-looking skin from week 6 — as long as you use it twice a day.
What to expect, week by week

Customer reviews
Reviewers love that Rejen is a Korean skincare finally made for melanin-rich skin — it melts in clear with no white cast, no ashy finish, no grey film. Women say their under-eyes look fresher, hollows fuller and dark circles softer, without the heavy, greasy feel of products "for dark skin." Many mention the glow, the fading lip lines, and how it changed the way they see themselves. The most repeated words: finally, no cast, and worth it.

No white cast. Finally. Every K-beauty stick I tried left a grey film on me — this one melts in clear and my under-eyes look awake by lunch. Week 5 and the hollow is less deep. I honestly didn't think a Korean product would ever work on my skin.
Glow in 30 minutes. No joke.
Our skin is complicated. A little dryness, a little hyperpigmentation, and it all shows more on us. Most "for dark skin" products are just greasy. This isn't — it sinks in, no ashy finish, and my smile lines are softer after 3 weeks.
Worth it at 47. My daughter asked what I changed.
I've spent years and a lot of money on skincare that was never made for me. This is the first time I feel like a brand actually thought about our skin. The hollows under my eyes look fuller and I finally feel confident bare-faced.
Caught the launch offer. Incredible for the price.
Reactive skin here — I get dark marks from everything. Zero reaction, zero fragrance. Just glow. That alone sold me.
My lips too. The little vertical lines are gone by morning. It lives in my purse now.
It changed the way I see myself. I know that sounds dramatic for a stick, but waking up and liking what I see in the mirror again is everything. My under-eyes don't drag my whole face down anymore.
Makeup sits better. Nothing creases.
I was skeptical about the 10% — thought it was just marketing. Six weeks in, the under-eye hollows are the biggest difference. My husband noticed before I even told him I was using something new.
Swipe, pat, done. So easy.
Finally a Korean lab that made something for us instead of exporting a watered-down version. The texture is light, not greasy, and it works on all four kinds of dark circles like they said. Reordering already.
No grey film at all. Incredible.
By the time I finish my coffee my skin looks like I slept nine hours. The glow is real and it's not greasy. I use it on the 11s between my brows too and they've softened.
My skin drinks it up. No film on my pillowcase like my old creams.
I have deeper skin and I'm always nervous about "glow" products leaving me ashy. This gives a real, healthy glow — not grey, not shiny. Honestly the first one that got it right for my tone.
Wish I'd found this years ago. Repurchasing for sure.
The 90-day guarantee is what made me finally try it, since nothing ever worked on my skin before. I didn't need it — I'm on my third stick. It's the one thing in my routine I won't skip.
No sting, no marks. Just works.
