Abstract: The invention concerns an injection implant for filling up wrinkles, thin lines, skin cracks and scars, for reparative or plastic surgery, aesthetic dermatology, and for filling up gums in dental treatment. The invention concerns the use of biologically absorbable polymer microspheres or microparticles suspended in a gel. The suspension is produced either ready-for-use or freeze-dried. The biological absorbability of the microspheres is controlled and enables the production of implants having well defined persistence and deliberately limited to 3 years.

Abstract: The present invention relates to a hydrogel of chitosan carboxyalkylamide, characterised in that it has a pH value close to that of the skin, comprised between 6.5 and 7.2, and in that the chitosan carboxy-alkylamide is constituted by 40 to 90 mole % of D-glucosamine N-carboxyalkylamide units of formula (I) where n represents an integer ranging from 1 to 8, from 60 to 10 mole % of protonated D-glucosamine units, and from 5 to 15 mole % of N-acetyl-D-glucosamine units. The present invention also relates to a dehydration product of such a gel and the cosmetic and/or dermatological utilisation of the gel and the dehydration product.
