Relipidizing Agents Phytosterols – This active ingredient improves the skin's lipid content. It also provides softness and strengthens its protective capacity against external agents. Essential Fatty Acids – These are found in the tissues of some fish and plant sources. The most well-known are alpha-linolenic acid (omega-3) and linoleic acid (omega-6). These help reduce water loss. At the same time, they hydrate and maintain the integrity of the dermis, allowing for better regeneration and firmness. A deficiency in this active ingredient can cause dry skin, roughness, and, in extreme cases, redness and inflammatory reactions. Protective Agents Sea Buckthorn Berry and Seed Oil Extract – Rich in vitamins C, E, and A and fatty acids; improves skin protection and defense. The oil extracted from these berries provides softness and facilitates water retention, preventing premature aging and protecting against the effects of free radicals. Sesame Oil – Contains fatty acids and vitamin E. In turn, it acts as an excellent protector, providing deep nourishment. Jojoba Oil – Jojoba comes from a shrub native to Mexico, and the oil is extracted from its seeds. It contains ceramides and vitamin E, which are known to increase elasticity and stimulate cell regeneration. It reduces transepidermal water loss without blocking sweat glands. Repair Agents Raspberry seed oil – Contains a high concentration of essential fatty acids, tannins, and vitamins E and B. It has an emollient and protective effect on the skin and, at the same time, combats free radicals. Furthermore, it helps balance the skin's protective barrier function and improve hydration levels. Blueberry Oil – Contains high levels of omega 3-6-9 fatty acids, which help repair the skin's hydrolipidic film. This, in turn, improves its protective and self-repairing function.

It improves the skin barrier, reducing water loss and protecting the skin from dehydration, ideal for dry or fragile skin.
