According to the query of Baidu Health Medical Beauty Network, gold microneedles can stimulate the repair of acne pit skin and the regeneration of subcutaneous collagen, but gold microneedles can only treat relatively small acne pits. If the pockmark is relatively large, the effect of gold microneedles will not be particularly ideal, but the price is relatively low, generally between 3000-5000 yuan. Lattice laser is a kind of laser. The wavelength emitted by laser can reach the dermis of skin, repair damaged skin tissue, stimulate the regeneration of subcutaneous collagen and repair large and small acne pits, so it will be more ideal than gold microneedles, but the price will be higher than gold microneedles, generally between 5000-8000 yuan. To sum up, compared with dot matrix laser, dot matrix laser is more effective for acne pits.
