The principle of the shuttle laser is similar to that of lattice, but the better technology developed by Taiwan Province Province is more advanced. On the basis of lattice, several generations of computers have been developed. If the lattice is compared to the first generation lattice laser, the shuttle laser can be equivalent to the fourth and fifth generation lattice technology. Actually, the principle is similar. Exfoliating grid is to grind the superficial layer and stimulate the deep collagen. The non-exfoliating lattice just stimulates deep collagen, hoping to help you.
