Biodegradable single-phase cohesive hydrogel characterized in that it comprises a homogeneous blend of x polymers, which may be identical or different, crosslinked prior to the interpenetration thereof by mixing in the form of a single-phase hydrogel, wherein said crosslinked polymers are insoluble in water and miscible with one another, and x is between 2 and 5. In one embodiment, the hydrogel according to the invention is characterized in that the x polymers have identical or different degrees of crosslinking, at least one of the x polymers having a degree of crosslinking x1 and at least one of the x polymers having a degree of crosslinking x2, with x1 being greater than or equal to x2. The invention also relates to the method for obtaining a hydrogel according to the invention and to the uses thereof, for example for the formulation of a viscosupplementation composition or of a composition for filling wrinkles. |
