What Is Silk Fibroin Powder Good For?

Silk Fibroin is a natural high molecular weight fibrous protein extracted from silk. It is a homologous protein to human epidermal protein and can be directly absorbed and utilized by the human body. It is composed of 18 kinds of amino acids, mainly glycine, alanine and serine. It has good biocompatibility and degradability, and the degradation time is controllable and the degradation product is highly safe. In addition, it has a unique molecular structure, excellent moisture absorption and antimicrobial properties.

Due to its obvious efficacy, safety and no side effects, it also has strong advantages and development space in the field of beauty and skin care. At the same time, it is also a new type of functional fiber, because it has unique properties and vigorous vitality that cannot be replaced by other fiber products and processed products.

What are the characteristics of silk fibroin?

• Good mechanical properties: It has excellent strength and toughness, and is suitable for medical applications that require a certain mechanical strength.
• Biocompatibility: It has good compatibility with human tissues and is not easy to cause immune response.
• Degradability: It can be gradually degraded and absorbed in the human body, the degradation time is controllable, and the degradation products are safe.
• Rich amino acid composition: It is rich in 18 kinds of amino acids, which helps promote skin repair and cell regeneration.

What are the effects of silk protein?

Moisturizing function: It has strong skin affinity. When it forms a film on the skin surface, it prevents the loss of skin moisture and keeps our skin in the best state of moisture content.

Anti-wrinkle function: Its fibrous protein can enhance the elasticity of the skin, accelerate skin metabolism, and prevent the formation of wrinkles.

Sunscreen function: Its tryptophan and galactobaric acid can greatly reduce the damage of ultraviolet rays to our skin.

Hair care function: After hydrolysis, it becomes silk peptide. Silk peptide has good film-forming properties and can give hair a glossy and moisturizing feel.

Improves the appearance of the skin: It can enhance the skin's radiance, making it look healthier and more vibrant. In addition, it can improve the overall appearance of the skin, such as reducing dullness and frostbite.

Anti-aging function: The main amino acids are very similar to collagen. At this time, it can accelerate cell metabolism, repair the stratum corneum, delay skin aging, and slow down aging.

How does silk protein help repair the skin?

Promote skin healing: It has the characteristics of activating the NF-B signaling pathway, which can regulate various cell behaviors in the wound healing process, showing great potential in skin wound healing.

Anti-inflammatory and reduce the risk of infection: It has natural antibacterial properties and can reduce the risk of postoperative infection.

Moisturizing and promoting skin nutrition: It contains a variety of polar amino acid residues, which are themselves an effective natural moisturizing factor. It has good moisture absorption and moisturizing properties, and can naturally form a film on the skin surface to prevent excessive evaporation of water, and play a role in regulating the humidity of small spaces on the body surface.

Application fields

Cosmetics

As a natural moisturizing factor, it can keep the skin at a certain moisture content and present a smooth and moist state. Long-term use of skin care products containing silk protein has good metabolism and water solubility, which can keep the skin moisture stable. As a natural skin care product, it has great advantages and development potential in the cosmetics field due to its obvious characteristics and safe and natural nature.

Biomedical field

It is a natural biomedical material with excellent performance and is widely used as a skin repair biomaterial. In addition, silk fibroin has not only been initially applied in vascular construction, tendon and ligament repair, chondrocyte stereo culture and surgical sutures. The application and development of silk fibroin drug carriers in the field of biomedicine has also become a hot topic of great concern to researchers at home and abroad.

Biological enzyme preservatives

When silk fibroin solution is used as a biological enzyme protective agent for material synthesis, it can directly react with toxic substances, combine into stable phosphorylated cholinesterase and block the damage of toxic agents to the human body. Studies have shown that it is feasible to use silk fibroin solution as a biological enzyme protectant. It has a good anti-toxic effect and can extend the shelf life of the enzyme.
