Penetration of Reactive Substances in the Skin Characterized by its Radical Status Factor (RSF)

GEMATRIA TEST LAB stellt seine Produktinformationen in den unten aufgezeigten Regionen zur Verfügung:

The effect of external treatments of the skin, as the topical application of substances (cosmetics-UV filter, antioxidants), the protection by textiles or the application of aggressive detergents influence the free radical status of the skin and can be characterized by the Radical Skin/ Status Factor RSF. This factor demonstrates the relation between the Radica l Status (RS) of the untreated (RS untr) and treated skin (RS tr) : RSF = RS tr/RS untr.

Substances or influences with a radical reducing effect results in a RSF > 1, with a radical increasing effect in a RSF < 1. No influence means accordingly RSF = 1. Therefore the RSF describes not only the UV- and Radical - protection of sunscreens but it is an universal factor for characterizing the whole radical status as a function of various exogenous and endogenous influences.
