Skin consists of epidermis, dermis and subcutaneous tissue. The epidermis has no nerves and blood vessels; The dermis is located under the epidermis and contains nerves and blood vessels.

The formation of scar, the elasticity and toughness of skin depend entirely on dermis, among which collagen, elastin, reticular fiber and hyaluronic acid are the main components of skin connective tissue, which maintain the elasticity and toughness of skin. Is to polish scars with an electric rotary grinding head. The advantages are strong pertinence, high speed and less treatment times; disadvantaged

The bleeding point is minimally invasive and needs to be bandaged. Suitable for large area scar and pigmentation. Is to use special equipment to stimulate the skin and promote skin growth. The advantages are less skin damage; The disadvantage is that

Autologous cell injection: that is, isolagen: take a small piece of skin from the ear of the beauty seeker, and then put it into the GMP international standard cell culture center for cell cloning. After 6-8 weeks of the first cell culture, 30-40 million fibroblasts, collagen, elastin and other components were cultured, and then injected into the sunken scar to grow naturally. Advantages: safety, physiology, naturalness, lasting curative effect, no rejection and other side effects. Disadvantages: cell culture requires high technology and high cost. Kunming Yan 'an Hospital, a public third-class institution, has exclusively launched a new scar-removing therapy that is popular all over the world. Global shining ion beam comprehensive scar removal therapy is the most advanced laser scar removal technology suitable for orientals, which can directly reach the depths of the dermal layer of the skin, stimulate the repair of the damaged dermal layer, and make the dermal layer produce more collagen and rearrange it, thus achieving the effect of skin rejuvenation.
