DESCRIPTION: Although Poly(methyl methacrylate), or PMMA, is widely known as a cosmetic agent for fillers for wrinkles and fine lines. According to Wikipedia, Poly(methyl methacrylate) is chemically "is the synthetic polymer of methyl methacrylate" (an organic methyl ester). It's naturally compatible with human tissue, and was a frequent component of contact lenses in the past; it's also been used for dentures and bone replacement, when combined with bovine collagen. When used in cosmetic surgery, Poly(methyl methacrylate) microspheres are suspended in biological fluid and injected under the skin to reduce wrinkles or scars permanently.
In skin care and beauty products, PMMA may act as a very mild form of sunscreen. According to its Plexiglas Acrylic Data sheet, PMMA filters ultraviolet (UV) light at wavelengths similar to ordinary window glass, about 300-400 nm. It does this by reflecting light away from your skin.
