ABSTRACT:
The present invention relates to the use of dehydroalanine derivatives of formula (I) ##STR1## with R.sub.1 : H or linear- or branched-chain C.sub.1 C.sub.4 alkyl, ##STR2## or linear- or branched-chain C.sub.1 -C.sub.20 alkyl where X.sub.1, X.sub.2, X.sub.3, X.sub.4 and X.sub.5 =H, halogen, hydroxyl, linear-or branched-chain C.sub.1 -C.sub.4 alkyl or alkoxy, ##STR3## and n=2, 3 or 4, for protecting the skin, the mucous membranes and/or the hair against oxidative stress and to the cosmetic and dermatological compositions containing such compounds and to new dehydroalanine derivatives.
