Abstract
The invention relates to the use of a spin trap employed as an electron paramagnetic resonance measurement probe, in a cosmetic or dermatological composition for the light-protective, anti-ageing and/or anti-acne treatment of the skin. In particular, this spin trap is encapsulated in lipid vesicles which are capable of diffusing into the deep layers of the skin.
