The pulse ablation CO2 fractional laser can instantly heat the water in the tissue to above 100 ℃, and when it acts on the skin, it vaporizes the epidermis and the dermis (scar) of different depths, causing the skin to produce vaporization pits. Let you have a more detailed understanding of why you choose to do fractional laser, and how to care for it after the operation?

Compared with the traditional laser, the fractional laser is more powerful and can reach the deep layer of the dermis of the human face, stimulate the damaged part of the dermal tissue to improve and proliferate, so that the dermis produces more collagen and rearranges it. Each pulsed laser is divided into nearly 100 micro-laser pulses, and each micro-laser spot is only 75-100um. When these tiny laser beams act on the skin surface, they will stimulate the growth of collagen and elastic fibers in the subcutaneous dermal tissue. , so as to fill in the pits, firm the skin and eliminate acne marks.

2. Is the operation of the fractional laser good for acne scars and acne pits?

7. Does fractional laser operation make the skin thinner?
