Cosmetic compositions containing water having a mineralization of at least 400 mg/l and an active agent having an irritant side effect exhibit a reduced irritant effect; the water is especially a thermal spring water and/or mineral water and the active agent is especially a keratolytic agent of the salicylic acid derivative type.

Cosmetic and/or dermatological composition containing thermal spring

Cosmetic or dermatological compositions containing at least one anti-aging active agent having an irritant effect, a cosmetically or dermatologically acceptable medium, and in addition, as an agent mollifying the irritant effect, a ceramide of the following formula (I): ##STR1## wherein A is ##STR2## R.sub.1 is a saturated or unsaturated, linear or branched C.sub.10 to C.sub.26 alkyl group;

Cosmetic and/or dermatological composition for the treatment of aging,

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.

Composition for combating ageing acting simultaneously on the surface

Cosmetic or dermatological compositions containing at least one anti-aging active agent having an irritant effect, a cosmetically or dermatologically acceptable medium, and in addition, as an agent mollifying the irritant effect, a ceramide of the following formula (I): ##STR1## R.sub.1 is a saturated or unsaturated, linear or branched C.sub.10 to C.sub.26 alkyl group;

Compositions containing, in a cosmetically and/or dermatologically acceptable medium, kojic acid and an ultraviolet screening agent chosen from the group consisting of benzylidenecamphor and derivatives thereof are effective for combating and/or preventing skin blemishes and for combating and/or preventing the ageing of skin.
