Potential of Silk Proteins in Cosmetics

Silk proteins, specifically fibroin and sericin, are promising for cosmetic applications due to their natural properties like anti-microbial, anti-oxidant, UV resistance, and moisture retention. They promote hair growth, enhance hair softness and shine, rejuvenate skin cells, and provide UV protection. Their low molecular weight allows effective penetration into hair and skin, forming a protective layer to prevent moisture loss. Silk proteins are biocompatible, biodegradable, and can stimulate collagen production, offering benefits such as skin hydration, wound healing, and anti-aging effects. They support eco-friendly and sustainable beauty solutions by utilizing unreelable cocoons, aligning with the trend towards natural ingredients in cosmetics.
