ALPHA AND BETA GLUCAN

Alpha and beta-glucans are polysaccharides, i.e. complex sugars that are present in nature. They are used in skincare because of their ability to stimulate the production of cytokines, molecules that regulate the skin's immune response.

Alpha-glucans, like those from yeast, have been studied for their ability to stimulate the production of epidermal growth factors (EGF) and interleukin-1 (IL-1). These molecules promote the proliferation of skin cells, which strengthens the skin barrier and prevents damage caused by UV rays.

Beta-glucans, like those from oats, have anti-inflammatory properties and stimulate collagen production. Collagen is a protein that gives skin its firmness and elasticity. By increasing collagen production, beta-glucans help reduce the appearance of fine lines and wrinkles.

Additionally, beta-glucans improve the skin's immune response by activating immune cells in the skin, such as macrophages and dendritic cells. This strengthens the skin barrier and helps protect the skin against external aggressions such as pollution and UV rays.

In short, alpha and beta-glucans are interesting ingredients in anti-aging skincare because of their immunostimulating, anti-inflammatory and moisturizing properties, as well as their ability to stimulate collagen production. Their beneficial effects have been scientifically studied and they are often used in anti-aging product formulations to help prevent the signs of aging and maintain healthy, glowing skin.
