The Research

Human skin possesses a perfectly balanced network of antioxidant vitamins, minerals, enzymes and proteins that work in unison to prevent the formation of harmful, ageing free radicals and glycation products resulting from daily environmental exposure. These same organic molecules are also the building blocks of healthy, glowing skin, boosting the synthesis of skin-firming collagen and elastin, while helping to control pigmentation and refine surface texture.

As we age, and as a result of sun and environmental damage, our natural levels of skin antioxidants are diminished, making topical supplementation essential.

The Vitality Actives

Vitamin C (Ascorbyl Tetraisopalmitate + Sodium Ascorbyl Phosphate) possesses hydro-lipophilic properties, allowing antioxidants to penetrate both water and oil soluble layers of the skin. This powerhouse antioxidant protects against cellular damage caused by the sun, controls melanogenesis to even out irregularities in pigmentation, as well as stimulating fibroblast activity and connective tissue synthesis.
Vitamin A (Retinol) stimulates skin connective tissue synthesis to retain firmness and elasticity. Controlling abnormal melanin production in the basal layer, this Skin Identical antioxidant vitamin refines skin texture and enhances skin radiance by directing cellular differentiation.
Vitamin E (Tocopherols + Tocotrienols) enhances Natural Moisturising Factors (NMFs) and reduces erythema and oedema within the skin, encouraging natural healing processes and helping to prevent Post-Inflammatory Hyperpigmentation (PIHP).
Ferulic, Ellagic + Palmitic Acid contain phytochemicals and flavanoids that provide Essential Fatty Acids (EFAs) to firm and nourish the skin while preventing lipid peroxidation.
Glutathione, Superoxide Dismutase + Ubiquinone (Coenzyme Q10) are anti-glycation antioxidants which deactivate the harmful effects of free radicals, preventing damage to skin cells induced by Reactive Oxygen Species (ROS) generated during exposure to solar radiation and pollution. These powerful antioxidants minimise glycation processes by preventing collagen and elastin degradation caused by solar and environmental damage.
