Encapsulation matters
Free retinol oxidises in 30 minutes once your bottle opens, and irritates the skin barrier in concentrations above 0.3 %. Lumière uses a polymer-encapsulated 0.5 % retinol that releases over 8 hours in the skin — equivalent efficacy to prescription tretinoin in a 24-week split-face trial, with a fraction of the redness.
Formulation highlights
- ●0.5 % microencapsulated retinol (slow-release)
- ●8 % squalane to support the lipid barrier
- ●Ceramide NP + bisabolol (anti-inflammatory)
- ●Airless pump, opaque glass — no oxidation
- ●Vegan, fragrance-free, EU-Cosmos compliant
How to start
Twice a week for 2 weeks, then alternate nights for 2 weeks, then nightly. Always pair with morning SPF 30+. Pregnant or trying to conceive — do not use.

What people say
"I tried tretinoin twice and gave up because of the peeling. This works without destroying my skin. Smoother forehead at 8 weeks."
