Description
Hyaluronic acid is one of the main components of the extracellular matrix. Being a very hydrophilic molecule has moistening function and improves skin hydration. It also contributes to the resistance of the skin to mechanical damage. Vitamin C, in addition to being a powerful antioxidant, is an essential cofactor for collagen synthesis, one of the major constituents of the extracellular matrix of dermis, the skin layer responsible for its strength and elasticity. Retinol (vitamin A) is a regulator of the proliferation of epidermal cells and the process of keratinization. It also has anti-inflammatory and antioxidant properties. Vitamin E contributes to the process of skin repair and modulates inflammation. Moreover, thanks to its antioxidant function, it contrasts the harmful action of free radicals at the skin level, slowing down cell aging and the appearance of wrinkles and dry skin. Vitamin B3 is a precursor for coenzymes of many metabolic reactions and is known for its antioxidant action. It also contributes to the maintenance of the barrier function of the skin, increasing the hydration and synthesis of lipids and proteins that constitute the skin barrier such as ceramides, keratin and philggrine. Helianthus annual seed oil contains oleic acid and linoleic acid, improves skin hydration and stimulates the proliferation of keratin and lipid synthesis at the skin level favors the maintenance and repair of the skin barrier.
