The present invention relates to pharmaceutical and cosmetic compositions comprising at least one agonist ligand, which is specific for receptors of the RAR-&ggr; type, which are characterized as inducers of apoptosis in at least one cell population in which apoptosis can be induced by activating receptors of the RAR-&ggr; type. In one aspect of the present invention, there is provided a method of combating photoinduced or chronological ageing of skin, said method comprising administering an effective amount of at least one agonist ligand which is specific for receptors of the RAR-&ggr; type to combat photoinduced or chronological aging of skin, wherein the agonist ligand has a ratio R which is equal to or greater than 10.

Use of a RAR-&ggr;-specific agonist ligand for increasing the rate of apoptosis

The use of at least one &ggr;-RAR receptor-specific agonist ligand to prepare a pharmaceutical composition for increasing the rate of apoptosis in at least one cell population in which apoptosis may be induced by activating &ggr;-RAR receptors is disclosed. The composition is particularly useful for treating a disease or disorder related to an insufficient rate of apoptosis in at least one cell population in which apoptosis may be induced by activating &ggr;-RAR receptors. The use of at least one &ggr;-RAR receptor-specific agonist ligand as the apoptosis inducer in a cosmetic composition is also disclosed. Said composition may be used to prevent and/or control photo-ageing or chronological ageing of the skin.

Methods of cosmetically or therapeutically treating diseases or disorders in cell populations whose pathology is linked to an inadequate rate of apoptosis by administering a therapeutically effective amount of 6-3-(1-adamantyl)-4-hydroxyphenyl)-2-naphthanoic acid.
