The electroporation micro-needle roller (model G5) adopts electroporation technology, LED phototherapy and massage. 1. The electroporation roller micro-needle adopts the electroporation technology, LED phototherapy and massage principle. Electro-perforation technology is one of the principles of micro-needle, which has specific to the skin, helps skin care products absorb more deeply and better, stimulates aging cells, improves cell activity, promotes collagen reorganization, and restores skin elasticity. 2. The micro-needle belongs to minimally invasive repair, which can effectively enhance the and reduce the tingling sensation caused by micro-targeted skin wounds by combining with the principle of electroporation technology. For example, to treat pockmarked skin, micro-needles with needle length ≥ 1.0mm should be used to roll on the skin, but the tingling feeling is obvious; If G5 is used, the needle length can be shorter than 1.0mm. Through the principle of micro-needle superposition electroporation, it can also meet the deep of skin, greatly reduce the trauma of micro-pointed skin, and reduce the tingling sensation of skin. 3. LED phototherapy: help skin heal and promote the absorption of cosmetics. 4. massage: help skin cells to rub, enhance cell activity, reduce the pain of micro-needles, and promote the absorption of skin care products.
