A process and composition for improvement of the moisturization state of the stratum corneum of human skin epidermis comprising applying to the skin an effective amount of a composition (C) for topical use comprising at least one cosmetically acceptable excipient and a composition C1 consisting of 20-50% by weight of composition C2, which in turn includes from 3-25% by weight of a polyol, from 25-45% by weight anhydrides of the polyol, and from 30-72% by weight of polyol glycosides of the polyol, with the remainder of composition C2 to 100% by weight being made up of water; and from 50-80% by weight of glycerol and/or glycerol oligomers, with the ratio of polyol glycosides to glycerol and/or glycerol oligomers greater than or equal to 1/10 and less than or equal to 1/2.

Process for short-term improvement of the moisturization state of human skin epidermis; novel moisturizing compositions

Disclosed is a lipophilic extract of brown algae gametophytes obtained by the method including the following consecutive steps: &#x2014;a Step A) for preparing a hydro-alcoholic suspension of gametophyte cells by mixing an aqueous suspension of brown algae gametophyte cells with at least one aliphatic alcohol including 1 to 4 carbon atoms; &#x2014;a Step B) for mixing the hydro-alcoholic suspension of algae gametophyte cells, obtained in Step A), with at least one triglyceride from fatty acids that include 8 to 22 carbon atoms; &#x2014;a Step C) for adding water to the multiphase mixture obtained in Step B); and &#x2014;a Step D) for isolating the lipophilic extract of brown algae gametophytes from the mixture obtained in Step C). Also disclosed are the cosmetic and pharmaceutical use of the extract.

Obtaining an extract from brown algae gametophytes, and use of said extract as a cosmetic anti-aging active principle

The invention relates to the cosmetic use of isoleucine N-hexadecanoyl of formula (I): CH&#x2014;(CH)&#x2014;C(&#x2550;O)&#x2014;NH&#x2014;CH(COOH)&#x2014;CH(CH)&#x2014;CH&#x2014;CH(I) as a 'volumizing' agent and/or as a 'plumping' agent for human skin. The invention also relates to a cosmetic treatment method for obtaining a &#x201c;volumizing&#x201d; and/or &#x201c;plumping&#x201d; effect of the skin of a part of the human body selected from among the breasts, face, cheeks, buttocks and eyelids.
