Microneedling stimulates collagen production by creating thousands of tiny openings in facial skin. As these “micro-injuries” heal, new collagen is formed, resulting in a firmer appearance. This treatment can also be used to minimize the appearance of acne scarring. Topical products (such as hyaluronic acid) may be applied at the time of treatment since the tiny openings allow for deeper product penetration. Dr. Bath may also suggest application of growth factors taken from your own blood (platelet rich plasma, or PRP) to further stimulate collagen production, a technique popularized by the “Vampire Facial.” Skin will appear blotchy and irritated for roughly 4 to 5 days following treatment. Multiple treatments may be required for best results.
