Definitions
- TITLE Anti-aging cosmetic composition based on resveratrol and magnolia
- the present invention relates to a cosmetic composition for combating the signs of aging of the skin and appendages in order to improve their appearance, as well as the cosmetic uses of such a composition such as a cosmetic treatment process using it.
- DNA Deoxyribonucleic acid
- CpG dinucleotides
- CpG sites cytosine-phosphate-guanine nucleic base sequences
- CG abbreviation for cytosine-phosphate-guanine
- CpG sites have a specific distribution in the form of islands of CpG sites in which their concentration is high and they then play a role in the regulation of gene expression.
- 5-hmC 5-hydroxymethylcytosine
- ten-eleven translocation enzymes hydroxylate 5-mC to 5-hmC.
- the magnolia is a tree of the magnoliaceae family and is native to China. It is a medicinal plant belonging to the Chinese pharmacopoeia.
- the bark of this tree is rich in lignans (ie phenolic compounds) including honokiol and magnolol which are active molecules.
- Honokiol has the following chemical formula (1):
- Magnolol has the following chemical formula (2): [Chem 2] [0014] It is known to use magnolia bark extracts which contain approximately 5% by mass of these two honokiol and magnolol molecules in cosmetic compositions for their anti-ageing, anti-acne and soothing properties.
- Cis-resveratrol has the following chemical formula (3):
- Irons-resveratrol has the following chemical formula (4):
- resveratrol can be in the form of a monomer or in the form of an oligomer comprising up to 4 monomer units (namely an oligomer comprising up to 4 times the repetition of the molecule of resveratrol).
- the term “resveratrol” designates both the monomeric form (with the 2 cis and trans isomeric forms) and the oligomeric form of resveratrol without distinction.
- Resveratrol is known for its anti-aging properties.
- resveratrol in the form of monomers or oligomers in which at least one hydroxyl group has been esterified or etherified.
- the hydroxyl groups of resveratrol are responsible for the instability in air and light of this molecule and for its water-soluble nature. This is why the protection of the hydroxyl groups of resveratrol by an ester group or an ether group is particularly beneficial, since it gives it satisfactory stability and makes it liposoluble (which also has the advantage of overcoming the problems of miscibility with many cosmetic excipients).
- these protective ester and ether groups are easily eliminated in vivo by cutaneous enzymes during the application of the cosmetic composition to the skin or appendages so as to "release" the resveratrol molecule which will then exert its activity. anti-aging on the skin or appendages.
- the inventors of the present invention have discovered a synergistic effect between the honokiol and magnolol molecules present in magnolia and resveratrol or one of its derivatives to combat certain signs of skin aging or appendages. Indeed, the inventors have discovered that the application to the skin or appendages of a cosmetic composition comprising the combination of these different molecules had an anti-aging effect greater than the cumulative anti-aging effects of honokiol and/or magnolol on the one hand and resveratrol and/or one of its derivatives on the other hand.
