Abstract
The invention relates to a cosmetic and/or dermatological composition comprising at least one superoxide dismutase and at least one porphyrin. In a composition of this kind the porphyrin synergically reinforces the anti-free radical action of the superoxide dismutase. The composition is used in particular to combat cell ageing and/or for the protection of the skin, hair and/or mucosae against the harmful and/or unaesthetic effects caused by oxygen-containing free radicals.
