    Abstract: The invention concerns a method for examining a sample whose surface comprises reliefs, and an apparatus for carrying out the method. The apparatus comprises a sample carrier plate subjected to illumination from at least two sources having different wavelengths and whose illumination axes form an acute angle of incidence on the sample carrier plate, the illumination axes of the sources being all different, and an observation system for the sample carried by the plate. The method may be used for measuring the effectiveness of a cosmetic treatment product on a skin.

    Abstract: The use of a photo-convertible carotenoid of formula (I) for the cosmetic treatment of the skin to protect it from photo-ageing, is new. R1, R2 = one of groups of formulae (II) - (IV), at least one of R1 and R2 being a beta -ionone cpd. (II); R3, R4 = H, OH, carboxy, 1-4C alkoxy pref. MeO, or forms a carbonyl group with the ring C atom. Also claimed are cosmetic or dermatological controlled-release compsns. contg. cpds. of formula (I) which may be converted into retinol and retinoic acid or their isomers; in a cosmetically- or dermatologically-acceptable medium.
