Stories from Nature
Soy (Glycine max) is an annual herbaceous plant of the Fabaceae family, native to East Asia and cultivated for millennia for its protein-rich seeds.
Like other legumes, it develops small nodules on its roots that harbor bacteria capable of fixing atmospheric nitrogen, thereby contributing to soil fertility. Through the process of hydrolysis, the proteins extracted from the seeds are broken down into smaller fragments, yielding functional ingredients highly valued in cosmetic research.
Today, it remains a much-loved food throughout Asia, especially among women, given their particular focus on the beauty of the face, body, and hair.
Hair Benefits
Hydrolyzed Soy Proteins, with their strengthening, moisturizing, and film-forming properties, help improve the appearance and strength of the hair shaft, especially in dry, damaged, and brittle hair.
They form a protective film that helps retain moisture and smooth the cuticle, promoting softness, elasticity, shine, and manageability. Working in synergy with other active ingredients, they support the reparative and protective action of specific treatments, helping to combat frizz, minimize breakage, and enhance body and volume.
They also complement formulations designed to provide cosmetic protection for hair against thermal and environmental stress, including sun exposure. In Scalp revitalizing treatments, they contribute to the overall effectiveness of formulas designed for fine and weakened hair.
Skin Benefits
Thanks to their moisturizing, conditioning, and protective properties, Hydrolyzed Soy Proteins help keep the skin soft and supple by stimulating collagen and elastin. Their film-forming action helps combat dehydration and improve the appearance of the skin’s surface.
In anti-aging skincare formulations, working in synergy with antioxidant and revitalizing ingredients, they support the treatment’s action, helping to improve firmness, tone, and radiance while reducing the appearance of signs of aging. They also complement formulas designed for delicate and stressed skin, or skin prone to hormonal aging, promoting skin comfort and providing cosmetic protection against environmental agents such as pollution and blue light.
