Sodium DNA

A derivative of deoxyribonucleic acid obtained from natural sources and used mainly in skincare. This substance supports cell regeneration, improves hydration and helps restore skin elasticity. In cosmetic products, it acts as an effective anti-ageing ingredient that supports a healthy, revitalised complexion. It is obtained through bioregenerative processes from plant or animal sources, such as salmon gonads or plant cells, or as a bio-extract by freeze-drying DNA from natural materials. This process preserves its biological activity and allows it to be widely used in modern formulations. Thanks to its structural properties, it supports cell communication and repair, making it ideal for advanced cosmetics focused on long-term revitalisation.

Sodium DNA acts as a powerful moisturising agent by binding water in the deeper layers of the skin and improving hydration by up to 200 % compared with conventional humectants. It restores the skin barrier by stimulating collagen and elastin synthesis, increasing firmness and elasticity. As an antioxidant, it neutralises free radicals, protects against oxidative stress and slows ageing. It supports cell regeneration by accelerating cell division and the repair of DNA damaged by UV radiation or pollution. At concentrations of 0,1 to 1 % in serums or creams, it significantly improves the appearance of the skin without irritation, ideally in combination with peptides or hyaluronan.

It is particularly recommended for dry, dehydrated, mature and sensitive skin, where it effectively combats the loss of elasticity and hydration. It is also suitable for skin after a peel or skin exposed to environmental stressors such as pollution or sunlight. For oily or acne-prone skin, it is beneficial in lightweight gel formulations, where it soothes inflammation without clogging pores. It is particularly suitable for women over 30 looking to prevent wrinkles and improve facial contours.

A study published in the Journal of Cosmetic Science (2018) showed that Sodium DNA at a concentration of 0,5 % increased skin hydration by 68 % and reduced wrinkle depth by 25 % after 4 weeks of application in women with mature skin. Further research in the International Journal of Molecular Sciences (2021) confirmed that, at a concentration of 0,2 %, it stimulated collagen production by 40 % in vitro in fibroblast cells, supporting renewal of the dermal matrix.
