Polymethyl Methacrylate
Ingredient Info
Polymethyl methacrylate (PMMA) is a synthetic plastic polymer used in skincare primarily as a film-forming agent in injectable fillers for facial rejuvenation. It works by providing structural support to sagging skin and can stimulate collagen production over time. This ingredient is not typically found in topical skincare products like serums or moisturizers.
Benefits
- Provides immediate volume and lift to areas like the jawline and chin
- Results can last several months to years depending on the formulation
- Minimally invasive compared to surgical alternatives
- May stimulate the body's natural collagen production for longer-term skin firmness
Potential concerns
- Requires professional injection—not suitable for at-home use
- Potential for allergic reactions, inflammation, or granuloma formation at injection sites
- Risk of lumps, asymmetry, or migration if not administered properly
- Not recommended for pregnant or nursing individuals
- Results are temporary and require repeat treatments for maintenance
Science: PMMA is recognized in medical literature as an established injectable filler for facial rejuvenation with a documented safety profile when used by trained professionals. The research indicates it is effective for jawline and chin augmentation with manageable risk profiles, though long-term safety data and comparison studies remain limited in peer-reviewed literature.
