Also referred to as collagen induction therapy, microneedling uses very fine needles to create equally fine channels through the surface layer of the skin. Even though the body loses collagen at a rate of about 1% per year after a person reaches their mid 20s, the body’s ability to create new collagen remains. It stays dormant until an injury causes a healing response. Microneedling triggers the healing response, although it creates little to no damage due to the fine, solid needles used. The microchannels created by the needles close quickly. There may be some pinpoint bleeding which typically stops within seconds.
Collagen resides in the deeper layer of skin, providing support to the surface. As collagen decreases, skin fullness suffers, and it begins to show signs of aging. With microneedling issuing the wake-up call, new collagen forms in the treatment area, propping up skin and attracting proteins such as elastin and hyaluronic acid to the area. It is a rejuvenation process created naturally by the body, and induced by the microneedling treatment.
Yes, there are. Many laser, pulsed light, and radiofrequency treatment systems, as well as other manual therapies induce collagen based on the same principle of controlled skin injury. Though the induction method varies, they all stimulate the body to create new collagen. Microneedling does have some advantages over other methods, making it an ideal addition to other treatments. Because the microchannels created during the treatment penetrate the skin, topical treatments may have enhanced absorption when combined with microneedling. Applying vitamin C and hyaluronic acid will strengthen and moisturize the treatment area, while bleaching serums may aid in pigment removal. Platelet-rich plasma therapy is also often combined with microneedling.
