Retinol is a safe bet in cosmetics, but the molecule is relatively unstable once it has been incorporated into a cosmetic formulation such as a skincare cream, which is why the Emuage machine makes it possible to exploit its full potential: the finished product can be applied to the skin directly after manufacture, with the active ingredient mixed in at the last moment, and not 2 years later as is the case with creams that can be bought in stores. Emuage skincare products should be used within 2 months of manufacture.

Benefits
Improves complexion radiance and skin color
Increases skin elasticity
Fights excess sebum

How it works
Retinol (at a moderate concentration of 0.05%) gradually penetrates the epidermis. It mainly promotes surface cell renewal and regulates melanin production, responsible for skin color. Its action on cellular oxidation mechanisms helps revive the complexion's natural radiance. It also promotes cutaneous microcirculation and tissue hydration, improving skin elasticity.

Studies
According to a study of 34 women aged 40 to 59 over 24 weeks (at 0.045% retinol to be precise):
Skin elasticity: +9% after 12 weeks (+5% for 0.2% retinol)
Complexion brightness: +2% after 4 weeks (+0.5% for 0.2% retinol)
Sebum: -23% after 24 weeks (-46% for 0.2% retinol)
