Abstract: The invention relates to novel propynyl or dienyl biaromatic compounds which have the general formula (I) as well as to the use of these compounds in pharmaceutical compositions intended for use in human or veterinary medicine (dermatological, rheumatic, respiratory, cardiovascular and ophthalmological complaints in particular), or alternatively in cosmetic compositions.

Abstract: A method for eliminating unwanted hairs is provided. The method includes applying an effective amount of a composition including microparticles to the surface of the skin where the hairs are situated and removing the composition remaining on the surface of the skin. The microparticles contain chromophores and a second material different from the chromophores. At least 80% by weight of the microparticles have a diameter of between 3 &mgr;m and 10 &mgr;m. A composition containing a solvent which dissolves the chromophores may then be applied to the surface of the skin. Laser radiation is then applied in one or more shots. The emitted wavelength of the laser radiation is absorbed by the chromophores. The light energy and the emission duration of the laser energy are sufficient to damage and/or kill the cells responsible for the growth of the hair.
