INCI: Hydrolyzed silk

What is Hydrolyzed silk?

Silk protein is a natural protein fiber. It is present in the cocoons of the silk worm, Bombyx mori. The silk protein consists of fibroin and sericin proteins. Silk is of different types depending on the insect that produces it. For more information refer silk.


Use & Benefits:

Hydrating: Silk protein is a natural humectant, which means that it can help to hydrate and moisturize the skin. When applied topically, silk protein can help to lock in moisture and prevent dryness.

Anti-aging: Silk protein contains amino acids that can help to stimulate collagen production in the skin. Collagen is a protein that is essential for maintaining skin elasticity and firmness, and its production decreases as we age. By promoting collagen synthesis, silk protein can help to reduce the appearance of fine lines and wrinkles.

Soothing: Silk protein has anti-inflammatory properties that can help to calm irritated or inflamed skin. It can also help to reduce redness and swelling, making it a useful ingredient for those with sensitive or reactive skin.

Protecting: Silk protein forms a protective barrier on the skin that can help to shield it from environmental stressors like pollution and UV radiation. This barrier can also help to prevent moisture loss and keep the skin hydrated.

Smoothing: Silk protein has a silky texture that can help to smooth out the skin's surface, making it look and feel smoother and more even.

Additional information:
•    Silk protein is rich in amino acids, which are the building blocks of proteins. These amino acids can help to nourish and strengthen the skin, promoting a healthy, radiant complexion.
•    Silk protein is also rich in antioxidants, which can help to protect the skin from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and contribute to premature aging.
•    Silk protein is a non-irritating ingredient that is suitable for all skin types, including sensitive skin.
•    In addition to its skincare benefits, silk protein is also used in hair care products for its smoothing and hydrating properties.
