Abstract: The invention provides the use of at least one alkyl-phthalide or a plant extract comprising mainly said alkyl-phthalide for the topical cosmetic treatment of the skin and of the scalp, in particular an anti-dandruff treatment. According to the invention, a CO2 supercritical extract of Apium graveolens seeds consisting mainly of sedanenolide may be used.

Abstract: A composition is described, comprising or consisting of chrysin, rosmarinic acid, at least one peptide or derivative thereof, having a sequence of 4 to 10 amino acids comprising the active sequence GQPR and a physiologically acceptable medium. A derivative corresponds to said peptide modified at the N-terminal end with an acyl (—CO—R1), sulfonyl (—SO2—R1) group or a biotinoyl group and/or at the C-terminal end with an OR1, NH2, NHR1 group or NR1R2, R1 and R2 being as defined herein and where the composition acts on the effects of light radiation on the skin and/or of its appendages, and more particularly the effects of blue light to fight against harmful effects and in a particularly advantageous manner at the same time to increase the beneficial effects by resynchronizing the circadian cycle.

Abstract: The treatment according to the invention provides the use of at least one peptide having the general Formula X-(Xaa)nK*TTK*X?aa-(Xaa)m-Z for a non-therapeutic cosmetic treatment of keratinous tissues of the skin and of its appendages, where X, Xaa, n, K*, X?aa, m and Z are as defined. A preferred peptide is the Pal-KTTKS.

Abstract: The invention provides the use of at least one alkyl-phthalide or a plant extract comprising mainly said alkyl-phthalide for the topical cosmetic treatment of the skin and of the scalp, in particular an anti-dandruff treatment. According to the invention, a CO2 supercritical extract of Apium graveolens seeds consisting mainly of sedanenolide may be used.

Abstract: The invention provides a method for the topical non therapeutical cosmetic treatment of the scalp comprising applying to the scalp an effective amount of at least one alkyl-phthalide or a plant extract comprising mainly said alkyl-phthalide. In particular, the treatment is an anti-dandruff treatment. According to the invention, a CO2 supercritical extract of Apium graveolens seeds consisting mainly of sedanenolide may be used.

Abstract: At least one cyclic peptide is described for use as an active component in a non-therapeutic cosmetic treatment of the skin and/or its appendages, the cyclic peptide consisting of at least five amino acids including at least one proline (Pro) and at least one two phenylalanine (Phe), the other amino acids being chosen from the group comprising leucine (Leu), isoleucine (Ile), valine (Val), alanine (Ala), glycine (Gly), methionine (Met) and tryptophan (Trp), methionine (Met), when present, may be unoxidized or oxidized.
