What is the principle of dot matrix laser in treating scars?

Alma laser treatment has a "columnar microperforation" treatment principle that other laser equipment can't match. The skin around the micropores is kept intact, and the energy control is very fine and will not spread to the periphery, thus ensuring the safety of treatment to the greatest extent. After treatment, tissue repair scaffolds were formed in the epidermis and dermis of the skin, and collagen gradually increased and rearranged, making scar repair more smooth. There is little possibility of side effects such as pigmentation and hypopigmentation.
