You can see it the first night.Most night serums ask for six weeks of faith. In its maker's testing, NovoRetin™ reduced the look of wrinkles and skin roughness after a single application — before any of the longer work has started.It is not retinol, and that is the point rather than the apology. Retinol adds a retinoid to your skin, with the dryness that comes with it. NovoRetin™, derived from mastic gum, raises the retinoic acid your skin already makes — and in its maker's studies it increased hydration instead of causing dryness.Over 28 days at 2% against placebo: skin elasticity +20.4%, skin density +13.8%. Pore count −30.3% and pore volume −41.7% within two weeks. We use it at 3% — 1.5× the studied concentration. Everything else in the bottle is base: sea buckthorn, licorice and hyaluronic acid sit at trace levels, and we claim nothing for them. Applied in the evening. Made in Carros, France.The research is Mibelle Biochemistry's own, into the ingredient rather than into this finished serum.Contains mastic gum, a documented contact allergen. Patch test on the inner arm and wait 48 hours before first use; stop if you react. For external use only. Avoid the eye area. Use broad-spectrum SPF 30+ each morning. Results refer to the appearance of skin and vary between individuals.
