Polyacrylamide for the Face

open access: yes, 2020
Polyacrylamide is a good nonabsorbable volumizing gel not approved by the FDA. It is considered a gel whose application is similar to hyaluronic acid, giving an excellent aesthetic result. It is preferably used in HIV-positive patients, because of their immunosuppression state, due to the risk of producing granulomas. Aquamid® from the European Company

Swelling of polyacrylamide gels in polyacrylamide solutions

open access: yesJournal of Polymer Science Part B: Polymer Physics, 1998
Swelling behavior of polyacrylamide (PAAm) and polyacrylamide-co-poly- acrylic acid (PAAm-co-PAAc) gels was investigated in aqueous solutions of monodis- perse PAAms with molecular weights (M V w) ranging from 1.5 1 10 3 to 5 1 10 6 g/mol. The volume of the gels decreases as the PAAm concentration in the external solution increases.
