Abstract:
According to the invention, at least one tyrosine derivative, in particular N-Palmitoyl-O-methyl-L-Tyrosine, is used for a cosmetic or nutraceutical treatment and/or the manufacture of a cosmetic or nutraceutical composition for improving the general condition of the skin and/or its appendages, in particular for a pro-pigmentation effect.
Abstract:
The invention provides the use of undifferentiated or dedifferentiated plant cells, whole and/or lysed, from Buddleja davidii Franch. obtained by an in vitro cell culture process, and/or an intracellular extract of said cells free of cellular debris, for a topical non-therapeutic cosmetic treatment to homogenize the complexion of the skin, in particular via prevention and/or treatment of pigment and/or skin texture heterogeneities. The treatment is particularly suitable for the treatment of skins of phototype III to V developing spots and areas of hyperpigmentation, and furthermore especially for the treatment of skin with olive carnation.
Abstract:
The use at least one alkyl phthalide or a plant extract comprising said at least one alkyl phthalide as the major component for a topical cosmetic slimming treatment. According to the invention, it is possible in particular to use a CO2 supercritical extract of seeds of Apium graveolens comprising sedanenolide as the major alkyl phthalide.
Abstract:
The ingredient comprises a mixture of unsaturated dicarboxylic acids comprising the Z and E isomers of at least one mono-unsaturated dicarboxylic C12-C24 acid, the concentration of the E isomer being of at least 25% by weight based on the total weight of Z and E isomers The ingredient can be used to form cosmetic or dermatological compositions, in particular for lightening the skin, improving the clarity and unification of the skin complexion.80
Abstract:
The invention is directed to the use of at least one peptide of formula: X –(Xaa1 ) n –Pro* –(Xaa2)m –Y (I) With: -n = 0, 1 or 2; -m =0 or 1and if m = 0 then n ≠ 0 -Xaa is: -An hydrophobic aminoacid selected from Alanine (Ala, A), Valine (Val, V), Methionine (Met, M), Leucine (Leu, L), Isoleucine (Ile, I), Phenylalanine (Phe, F), Proline (Pro, P) and analogues and derivatives thereof; -A polar aminoacid selected from Serine (Ser, S), Threonine (Thr, T), Tyrosine (Tyr, Y), Asparagine (Asn, N), Glutamine (Gln, Q)and analogues and derivatives thereof; or -Glycine (Gly, G); When n = 2 the two aminoacids Xaa1 can be the same or different; -Xaa2 is: -An hydrophobic aminoacid selected from Alanine (Ala, A), Valine (Val, V), Methionine (Met, M), Leucine (Leu, L), Isoleucine (Ile, I), Phenylalanine (Phe, F), Proline (Pro, P) and analogues and derivatives thereof; -A basic aminoacid selected from Arginine (Arg, R), Lysine (Lys, K) and Histidine (His, H) and analogues and derivatives thereof; -Glycine (Gly, G) or Serine (Ser, S); -At the N terminal end of the peptide, X is selected from H, -CO-R1 and -SO2 -R1; -At the C terminal end of the peptide, Y is selected from OH, OR1, NH2, NHR1 or NR1 R2, -R1 and R2 being independantly from each other, selected from an alkyle, aryle, aralkyle, alkylaryl, alkoxy and aryloxy group, that can be linear, branched, cyclic, poly-cyclic, non- saturated, hydroxylated, carbonylated, phosphorylated and/or sulphured, with the possibility to have in said group skeleton a O, S and/or N heteroatom; -Pro* corresponding to a Proline, an analogue or derivative thereof; Excluding the peptides where X=H and Y=OH, for a non therapeutical cosmetic pro-pigmenting treatment of skin. The invention also encompasses new tripeptides of formula (I) suitable for a non therapeutical cosmetic treatment of skin.
Abstract:
The present invention provides a topical composition comprising: -A mixture of bioactive sulfated oligosaccharides having a degree of polymerisation (DP) comprised between 2 and 10, and -A physiologically acceptable medium; said oligosaccharides being obtained according to an enzymatic cleavage process according to a beta- elimination reaction of polysaccharides extracted from green algae of the ulvagenus comprising aldobiuronic sequences and glucuronan sequences using an ulvan-lyase enzyme adapted to cleave the osidic bond between the units of Glcp A Rhap3 sulfate and between the units Idop A and Rhap3, and using a glucuronan-lyase enzyme adapted to cleave the osidic bond between two Glcp A units. Such a composition has a particularly interesting cosmetic activity on the skin cells, including anti- inflammatory, anti-radical, de-pigmenting effects and effects on molecules of the dermal extracellular matrix (such as collagen 1, collagen 4 and fibronectin), on molecules of the epidermal extracellular matrix (hyaluronic acid). Applications: anti-aging and moisturizing
Abstract:
The present invention concerns a new cosmetic use of Tyr-Arg dipeptide to stimulate molecules of the extracellular matrix in order to prevent and treat cutaneous sagging, in particular due to natural gravity. The invention presents application in the formulation of tightening, fïrming, contouring, lifting cosmetic products.
Abstract:
The present invention related to cosmetic compositions comprising oridonin and new cosmetic uses. Oridonin is used forfighting the signs of cutaneous ageingand for slimming. A composition comprising a combination of oridonin and darutigenol or a derivative thereof, in particular darutoside, is disclosed together with the cosmetic use of such composition.
Abstract:
The subject matter of the présent invention is the cosmetic and topical use of xanthohumol as active ingrédient, including inhibiting the GMCSF production for brightening complexion and/or reducing cutaneous redness.
Abstract:
The present invention relates to cosmetic compositions comprising an association of hydroxymethionine and 3-aminopropanesulfonicacid, and a cosmetic methodfor the skin. These compositions are intended to prevent and/or treat the signs of the cutaneous ageing such as the sagging of the cutaneous and subcutaneous tissue, the loss of cutaneous elasticityand atonyofthe texture of the skin, the loss of firmness and tonicity,dermal atrophyand loss of density,wrinkle, little wrinkle, crack.
