Sericin, a silk protein, is widely applied in cosmetics due to its excellent bioactive properties. Here’s an overview of its uses in cosmetics:
1. Moisturizing Agent
- Sericin has a strong affinity for keratin, enabling it to form a protective film on the skin or hair.
- It retains water effectively, enhancing hydration and maintaining skin elasticity.
2. Anti-Aging Properties
- Rich in amino acids, sericin promotes collagen synthesis and reduces the appearance of wrinkles and fine lines.
- Its antioxidant activity protects the skin from oxidative stress and environmental damage.
3. Skin Barrier Protection
- Sericin forms a thin, breathable layer on the skin, shielding it from pollutants and irritants.
- This protective layer also helps in reducing transepidermal water loss (TEWL).
4. Skin Brightening
- It improves skin texture and tone by reducing melanin synthesis, leading to a brighter complexion.
- Regular use can minimize hyperpigmentation and dark spots.
5. Wound Healing
- Sericin accelerates skin repair by promoting cell regeneration, making it suitable for healing minor cuts, burns, or irritations.
6. Anti-Inflammatory Effects
- It soothes inflammation, redness, and irritation, making it ideal for sensitive or acne-prone skin.
7. Hair Care
- In shampoos and conditioners, sericin enhances hair smoothness, strength, and shine.
- It repairs damaged hair cuticles and reduces split ends.
8. Delivery System for Active Ingredients
- Its film-forming ability helps in encapsulating and gradually releasing active compounds, improving the efficacy of skincare formulations.
