The laser is emitted in a scanning lattice method to form a burning area composed of laser action lattices and intervals on the epidermis. Each laser action point is composed of a single or several high-energy laser pulses, which can penetrate directly to the dermis layer in an instant. It vaporizes the tissues in wrinkles or scars and stimulates the proliferation of collagen, which in turn initiates a series of skin reactions such as tissue repair and collagen rearrangement. Under the action of the laser, collagen fibers shrink by about one-third, small wrinkles are flattened, deep wrinkles become shallower and thinner, and the skin becomes firm and shiny.

Laser through the CO2 laser's microvascular reconstruction effect, the oxygen content of vaginal tissue will increase, mitochondria will release more ATP, cell function will be more active, and then the secretion of vaginal mucosa will be enhanced, the color will be lighter, and the lubrication will be enhanced. At the same time, through restoration the vaginal mucosa normalizes the PH value and flora, reduces the recurrence rate of infections, and restores female reproductive tissues to a younger level. In addition, the private laser completely subverts the traditional birth canal repair method: painless and non-invasive to solve the problems of postpartum genital tract leakage, relaxation, decreased sensitivity and lubricity, and repeated inflammation.
