Abstract: Methods for obtaining an aqueous extract of a microalgae Dunaliella salina cultivated in the absence of light in a culture medium of a yeast extract, sugar and salt include solubilising a yeast extract in water then adding sugar and salt. After solubilisation of the salt and at a pH between 5 and 8, the microalgae Dunaliella salina is added with stirring, in darkness and at room temperature, for a fermentation period of at least 12 hours. After the fermentation period, grinding and filtering are performed to separate a soluble aqueous raw extract to which salt is added. This extract undergoes sterilising filtration with a porosity threshold of less than or equal to 0.2 μm and has a pH between 3.5 and 4.5. The extract obtained by the method, compositions incorporating the extract, and methods of skincare, scalp care and skin appendage care using such compositions are also disclosed.

Abstract: The present invention provides a process for obtaining an extract from peach flower extract (Primus persica L.) for skin cosmetic use, a peach flower extract obtainable by the process and a cosmetic composition comprising the said extract. The invention further provides a method for modulating the SIRT2 expression, a method of treatment designed to reduce and/or correct the signs of aging and photo-aging of the skin and keratinous appendages, and to protect the skin against aggressions due to ultraviolet radiation.

Abstract: The present invention relates to a synergistic extract of Palmaria palmata and of jasmine flower heads, obtained after aqueous extraction of Palmaria palmata, in which maceration of the jasmine flower heads is then carried out, the ratio of the dry weight of Palmaria palmata to the dry weight of the flower heads being between 40/60 and 95/5.The present invention also relates to a method for obtaining said synergistic extract and cosmetic compositions comprising said extract as an active agent.The invention finally relates to the cosmetic use of said composition for combating the signs of aging and for improving the elasticity of the skin, by favoring maintenance of the “stem” character of the adult dermal stem cells (SKPs).
