Sirtalice is an active ingredient derived from marine biotechnology technology. It is known for its instant tensor effect and its action on the firmness of the skin. Specifically, Sirtalice is an extract of marine microalgae that contains sulfated polysaccharides.

It is derived from the technology of sirtuins, which are regulatory enzymes of cellular metabolism.

Sirtalice works by stimulating the natural production of sirtuins in skin cells, which helps to strengthen the cells' resistance to environmental stresses such as pollution, UV rays and oxidative stress. This helps prevent cell damage and reduce signs of premature aging, such as wrinkles, fine lines and loss of firmness.

The optimal concentration of Sirtalice in anti-aging face care products is 2%. At this concentration, it has been shown to have a visible effect on the skin by reducing wrinkles and improving skin firmness. Additionally, Sirtalice is considered a safe and effective ingredient, with clinical results demonstrating its effectiveness on different skin types.

In summary, the interest of Sirtalice in anti-aging face care is that it stimulates the production of sirtuins, thus strengthening the skin's resistance to environmental stresses and helping to prevent the signs of premature aging. A concentration of 2% is recommended to obtain visible and effective results.
