Phyto-Nature Firming Serum is Dermalogica's most advanced anti-aging serum yet! This dual-phase serum protects skin from external lifestyle factors, such as stress, UVA/UVB rays, poor sleep, pollution and reactivates how younger skin cells act. In the firming phase, collagen cells are activated to turn over more quickly to increase firmness, while peptides help rebuild and repair after external damage. In the lifting phase, camu camu super fruit and Madagascar green coffee beans, both rich in antioxidants, reduce inflammation and protect against free radicals. Technology enhanced hyaluronic acid penetrates deeper into the skin to hydrate and create a filler effect.
