aesthetic-awardsDermapen: High-frequency needles (5 synchronous needles as a minimum) apply either hyaluronic acid and/or PRP (platelet-rich plasma) to the deep skin layer (dermis), which has a significant positive effect on skin structure/elasticity and also improves scarred areas (e.g. post-acne, after surgery and accidents) enormously. The treatment is not painful (sensation of vibration comparable to an electric toothbrush); redness may persist for up to 2 days.
