Serisilk™ is made from the cocoon of the domestic silkworm (Bombyx Mori). Its main active ingredient known as sericin is a thick 'glue-like' protein super-molecule scientifically known for its strong affinity for human skin and its miraculous ability to protect, nourish and hydrate better than any other skincare ingredient in the market. In the medical field, it has been prominently used in the field of biomaterial synthesis and tissue engineering. Numerous scientific studies validate its powerful properties especially in the field of skin repair and regeneration. 

Sericin is a skin superfood widely known to have demonstrated the following incredible effects on human skin in real scientific studies:

1. Anti-Inflammatory effect[1] by significantly lowering the amount of inflammatory molecules produced naturally in skin.

2. Pro-Circulatory effect[1] by increasing blood flow through tissues (angiogenesis).

3. Anti-Scarring effect[1] by regulating Transforming Growth Factors (TGF) β1 and β3.

4. Rapid-Healing effect[1] by recruiting Mesenchymal Stem Cells to sites of injured or damaged skin.

5. Anti-Wrinkle effect[4] by increasing skin's natural levels of collagen.

6. UV-Solar-Protection effect[3] by being a natural guard against ultraviolet radiation.

7. Strong hydrating effect[2] by mimicking NMF (Natural Moisturizing Factor) and forming a skin barrier that reduces TEWL (Trans-Epidermal Water Loss).

Sericin has been studied as a cosmetic ingredient for decades and can be found in very small concentrations in some skincare products. However they are used in miniscule concentrations due to a very challenging manufacturing process and is mainly used for aesthetic reasons. Alexandr&Co's unique Serisilk™ manufacturing technology solves this problem, allowing sericin concentrations to be achieved higher than any other product on the market.

In its natural state, sericin is very difficult to incorporate into a cosmetic product in a high concentration due to its thick, viscious nature that affects consistency and absorption. Serisilk™ employs a special extraction method which allows for the production of the highest concentration of silk sericin possible in a skincare product, guaranteeing its efficiency as a powerful skincare ingredient and allowing it to show maximum benefit on your skin.

Additionally, sericin's molecular integrity can easily be compromised through poor manufacturing processes, denaturing and destroying the molecular structure through excess heat treatment and pH imbalances. Alexandr&Co's Serisilk™ contains sericin of a perfect molecular weight that provides maximum results, while remaining small enough to properly penetrate deep into skin tissues.
