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.

Makeup sits better

I swipe it before concealer and nothing creases anymore. My smile lines look softer after 3 weeks. Not greasy at all.

My lips too

I use it on my lips at night and the little vertical lines are gone by morning. It lives in my purse now.

Worth it at 47

I was skeptical about the 10%. Six weeks in, my daughter asked what I changed. The under-eye hollows are the biggest difference.

FAQ

Questions? Answered.

All four faces: hollow, dark, puffy and crepey. Most women have more than one, so swipe it under the eye morning and night.

No. The balm melts in clear and leaves a soft glow, with no white or grey film on deeper skin tones.

We left out fragrance and essential oils, two common sources of irritation. If your skin is reactive, patch-test on your jawline for 24 hours first.

Hydration and glow are instant. Lines look softer from 2 weeks, and hollows look fuller from 4–8 weeks of twice-daily use.

High-percentage Volufiline oils are meant to be diluted into your cream, and many people apply them wrong. Our stick is pre-dosed at 10%: one swipe, nothing to mix.
