Stylage M is a cross-linked, non-animal hyaluronic acid gel that is sterile, apyrogenic, and has physiological pH and osmolarity. This injectable implant is indicated for filling medium to deep wrinkles via injection into the mid- or deep dermis of the face or the lips. It can also be used to rejuvenate the hands via sub-cutaneous injection. While Stylage M generates volume immediately upon injection, it will eventually be resorbed into the body due to its biodegradable nature. As a result, this treatment is impermanent, and should be refreshed yearly to maintain results.
