Collagen is a highly effective way to “plump up” the skin, joints, bones, and ligaments. A naturally occurring protein in the second layer of skin (the dermis), collagen counteracts the thinning effects of aging, sun damage, and years of facial muscle movement by filling out sunken areas and smoothing lines for a rejuvenated look. Dr. Pazmiño recommends collagen over other facial fillers for adding volume and contour to the lips and cheeks. Results last several months, depending on the patient’s age, genetic background, skin quality, lifestyle and the body site being treated. The procedure may be combined with laser resurfacing or facial plastic surgery for a longer-lasting outcome.
