Made to work together. Stop searching, start layering.

Why K-beauty fans rebought

  • 🔥 200M+ TikTok views & counting
  • 🇰🇷 Made in Korea · Direct from brand HQ
  • ✅ Irritation score 0.00 (clinical patch test)
  • 🛡️ 30-day money back guarantee

What changes in 4 weeks

  • Week 1 — skin feels smoother, more hydrated
  • Week 2–3 — tone evens out, dark spots fade
  • Week 4 — measurable lift in fine lines, firmness, and barrier

What the clinical study measured

  • Fine lines: +114% improvement
  • Skin firmness: +109% improvement
  • Skin resilience (barrier): +163% improvement

*Tested by Korea Institute of Dermatological Sciences. 22 adults (ages 21–39), 4-week trial. Baseline = 100%. Individual results may vary.

Will this work for me?

"I have sensitive skin"
Both formulas tested at irritation score 0.00. The 100ppm retinal is encapsulated in micro-liposomes 800× smaller than pores — it absorbs deep without irritating the surface.

"I've tried strong actives and they were harsh"
The micro-liposome delivery means active strength without surface contact. You get the result without the typical purge, redness, or peeling.

"I already have a moisturizer I love"
The squalane step seals the serum in and repairs your barrier overnight. 8% squalane + 3% panthenol — light enough to layer under or over anything.

What's in the bottle

🖤 Step 1 — Retinal Skin Booster Serum

  • 100ppm Retinal (micro-liposome encapsulated, 800× smaller than pores)
  • For: tone correction, fine lines, dark spots
  • With: Niacinamide + Centella Asiatica

🤍 Step 2 — Squalane Skin Booster Moisturizer

  • 8% Squalane + 3% Panthenol
  • For: moisture barrier, calming, plumping
  • With: Ceramide NP + 7 types of Hyaluronic Acid

How to use it

  1. AM/PM — apply 2–3 pumps of Retinal Serum to clean, dry face
  2. Within 60 seconds — follow with Squalane Moisturizer to seal
  3. First 2 weeks — start every other night, then go daily
  4. Always — wear SPF 30+ in the morning (active ingredients increase sun sensitivity)

glass skin duo

I think I used it for nearly a month and all I can say is that its good products if you use them consistently

Wasn't expecting much honestly

I mainly got this because of my hyperpigmentation. I have darker skin and my spots usually take forever to fade so I really wasn't expecting much from this. Been using it for a few weeks now and my skin definitely looks more even. The marks on my cheeks aren't as noticeable and my skin just looks healthier overall. Also didn't irritate my skin which was my biggest concern. Still using it but so far I actually really like it.

second bottle & no more red bumps

Same chicken-skin texture and red bumps on my upper arms forever. Couple months of nightly use and you can finally see actual skin instead of irritation. On my second bottle now.

forehead lines are fading

The lines on my forehead were freaking me out because my mom got hers in her late 30s and I was terrified mine were starting too. But after two months of using this, they look way softer and Im going to keep using it until they are completely gone.
