Origin
Hydrolyzed SilkA moisturizing ingredient obtained from natural silk. Some studies have shown that hydrolyzed skin proteins have anti-inflammatory properties.
Retinol
Est. %0.1
Function
Origin
Retinol

One of the most famous and well-researched anti-aging ingredients with a maximum anti-wrinkle power of 10 out of 10. It is proven to decrease wrinkles and help the skin regain its thickness, firmness, and texture. Retinol is also effective in treating pigmentation issues such as dark spots and acne.
