The invention concerns the use of peptides of general formula R1-L-Tyr-L-Arg-R2 in which R1 = H or a R3-C = O with R3 = a C1 to C20 alkyl chain. linear or branched, saturated or unsaturate, hydroxylated or not, or with R3 = an aryl, aryl-alkyl or alkyloxy or aryloxy or arylalkyloxy group, and in which R2 = OH or a O-R4 group with R4 = a C1 to C20 alkyl chain, or R2 = a NH2, NHX or NXX group with X = a C1 to C4 alkyl chain. The peptides have a soothing effect on the skin, including by topical application, and attenuates the effects of benign skin sores ( after shave irritation, sunstroke, frostbite, chaps, depilation). They are used in acceptable cosmetic excipients and in effective in vivo concentrations. |
