2. Anti-ageing efficacy proven in studies on human (ex vivo)

• Significant increase (20 to 30%) in collagen i from day 4 and iii synthesis in the dermis from day 9.
• 10% significant increase in epidermal thickness from day 4
• Excellent skin tolerance - In contrast to the results usually obtained with vitamin A-based products (retinol, retinaldehyde, retinoic acid), which generally cause inflammation and a decrease in cell viability, Duolys.A Intensive Anti-Wrinkle Serum offers optimal skin tolerance and does not affect cell viability.

Use: Apply a small amount of Duolys.A to the face, neck and neckline, preferably in the evening, to previously cleansed skin.

Avoid contact with eyes. For optimal results, use as a 3-month repeatable treatment. It can also be used in combination with Duolys.CE or as a follow-up treatment for cosmetic procedures.
