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.
