Abstract
Compositions comprising a first dispersion of lipid vesicles which are capable of penetrating into the deep layers of the skin and which contain at least one active agent chosen from moisturizing agents, anti-free-radical agents, keratolytic agents, protides, enzymes, anti-elastase agents and anti-collagenase agents, and fatty acid derivatives, for treating these deep layers, and a second dispersion of lipid vesicles which are capable of penetrating into the surface layers of the skin and which contain at least one active agent chosen from keratolytic agents, tensioning agents, moisturizing agents, surface-restructuring agents and anti-free-radical agents, for treating these surface layers, are effective for combating ageing, acting simultaneously on the surface layers and deep layers of the skin.
