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 ?m 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 non-invasive, in vivo, DISC-type methods of evaluating structural changes in skin due to a variety of exogenous or endogenous factors. It is possible to develop quantitative and qualitative characterizations of skin. For example, the skin may be characterized based on its structural age rather than its chronological age. Based on the structural age and type of an individual's skin, cosmetic, dermatologic, medicinal or manipulative treatment may be customized. The method is based, in part, on quantification of discontinuities that arise in the skin during normal facial expression. The methods provide for evaluating changes in human skin response that occur over a short term (one day) or long term (one or more years). The methods provide for evaluating the skin's response to cosmetic, dermatologic or medicinal treatment or to any other factor alleged to affect the skin.

The composition according to the invention may have the appearance of a fluid or a cream and has specific rheological behavior: its shear rate changes over time, in particular when applied to the skin, where it “breaks” and promptly releases the aqueous phase, affording a great sensation of freshness. This composition may be used in particular in cosmetics and/or dermatology.
