Dermalogica Phyto-Nature Firming Serum is an anti-aging serum for mature skin. The latest studies in epigenetics suggest that our exposome (the set of environmental and lifestyle factors that influence the expression of our genes) is responsible for more than 50% of the visible signs of skin aging. Phyto-Nature Firming Serum does not promise eternal youth in a bottle, it does not make false promises, but rather gives back to your skin what is damaged by the exposome. In clinical studies, this serum has been shown to: reduce visible skin aging by 5 years, reduce the appearance of fine lines from the first application, double the skin's radiance after the first application, reduce visible wrinkles after 4 weeks, awaken the skin's innate power. For the first time ever, Dermalogica uses biomimicry, a scientific approach that mimics nature to enhance certain physiological processes. Phyto-Nature Firming Serum is a biphasic serum that contains a firming phase stimulated by biomimetic peptides linked to Sapphires that firm the skin and strengthen the skin's defenses against the exposome. Sapphires help stabilize the peptides and increase their bioavailability as they work to mimic the typical characteristics of young skin that worsen with aging.
