Silk Extract

Silk extract is derived from silk fibroin, a natural protein produced by silkworms. In skincare formulations, it functions primarily as a skin conditioning agent, helping to improve the texture and feel of products whilst supporting the skin's moisture barrier.The extract contains bioactive compounds including amino acids and antioxidants. When incorporated into skincare products, these components may contribute to the formulation's overall antioxidant and soothing profile, though the concentration and bioavailability in topical products requires further investigation.

Silk extract works primarily through its amino acid and protein composition. These molecules help to film-form on the skin surface, trapping moisture and creating a smoother feel. The antioxidant compounds present in the extract, such as flavonoids, may neutralise free radicals that contribute to oxidative stress and skin ageing.At a cellular level, research suggests these bioactive compounds may support skin cells' natural defence mechanisms, though topical efficacy depends on penetration depth and formulation stability.

Silk extract is typically used as part of a broader formulation rather than as a standalone active ingredient. It works well within serums, moisturisers, and treatment products. Because it functions primarily as a conditioning agent, you can use products containing silk extract daily as part of your regular skincare routine without adjustment.

Silk extract is generally well-tolerated across skin types. Those with silk allergies or sensitivities should check formulation details, though reactions are uncommon.
