The most recent scientific evidence suggests that the mechanisms by which environmental pollution causes damage to the skin are: free radical formation, alteration of the skin microflora, activation of the aryl hydrocarbon receptor (AhR) and of the inflammatory cascade. PM2.5 can cause alterations in the epidermis by increasing cholesterol synthesis with a transient accumulation of epidermal cholesterol content and decrease of squalene.2
Data show that a pure, regenerated sericin, obtained by a circular economy process, has an anti-pollution effect, creates a protective film on the skin and hair and promotes the removal of atmospheric particulate matter. The regenerated sericin helps prevent the accumulation of particulate matter on the epidermis and improves skin appearance, making it brighter and smoother. Applied on the hair, it has shown to exert a filmforming action and promotes an ‘instant repair’ effect.
Sericin regeneration is an example of
