PMMA (polymethylmethacrylate) filler is a semi-permanent to permanent dermal filler made of microspheres suspended in a collagen carrier. Unlike temporary fillers that the body absorbs, PMMA stimulates collagen production while the microspheres remain in place long-term, creating lasting volume and support in treated areas. It is commonly used to address deeper lines, folds, and volume loss on the face and neck.

PMMA filler suits patients seeking longer-lasting results than conventional temporary fillers and who are comfortable with a semi-permanent commitment. Ideal candidates have realistic expectations, are in good health, and wish to address deeper wrinkles, nasolabial folds, marionette lines, or other areas requiring sustained volume restoration. A qualified provider will assess individual anatomy and goals during consultation.

The procedure begins with cleansing and marking the treatment areas. Your provider will inject the filler using a fine needle or cannula, typically administering small amounts in strategic locations to build volume gradually. Most sessions last 30 to 60 minutes depending on the areas treated. Discomfort is generally minimal, though numbing cream or local anesthetic may be used.

Most patients experience mild swelling, redness, or bruising at injection sites, which usually resolves within a few days. Avoid strenuous exercise, excessive heat, and facial massages for at least 24 to 48 hours after treatment. You can typically return to normal activities immediately, though some providers recommend waiting a day before applying makeup.

Initial results appear within days as swelling subsides, with final results visible after 2 to 4 weeks as collagen remodeling progresses. PMMA filler is designed to last years or longer, making it one of the more durable filler options. Individual longevity varies based on metabolism, injection depth, and volume injected; your provider can discuss expected duration for your specific treatment.
