Micro-Mechanical Fractional Skin Rejuvenation

The study introduced a novel device using micro-coring needles for fractional skin rejuvenation, which was tested on a pig model. Compared to standard needles, the coring needles significantly increased fibroblast activity and collagen synthesis, with the treated sites showing up to 196% thicker dermis and epidermis at 1 month and an 89% increase in collagen content at 3 months. The treatment sites healed quickly without scarring or infection, demonstrating the potential of this method as a safe and cost-effective alternative to laser resurfacing for treating age-related skin issues.
