Microneedling and CO2 laser resurfacing function similarly in how they stimulate collagen and elastin production in that they both cause micro-wounds to the lower layers of the skin, and healing from those wounds is what stimulates the production of those chemicals. However, microneedling causes those tiny wounds by actually puncturing the skin with very small but sharp needles, and CO2 laser resurfacing causes the wounds by heating the lower layers of the skin via the laser. Neither treatment is considered painful but seems to elicit the same amount of discomfort during the procedure. As well, one of the reasons you see some results in the early stages following a CO2 laser resurfacing treatment is that the procedure removes the top layer of skin which causes the skin to regenerate new skin cells. Microneedling does not damage or remove the top layer of skin, it only affects the lower levels of the dermis. CO2 laser resurfacing treatments, which help to penetrate deeper into the skin, boosting skin rejuvenation for a softer, silkier, and smoother appearance are available at the Center for SmartLipo & Plastic Surgery.
