Some lighter skin injuries, such as abrasions, superficial burns or scalds, heal and leave a heavier discoloration, although the scarring is not very heavy. The injured skin is visibly different from the surrounding area and can seriously affect the appearance, as in the face. Traditional treatments for this hyperpigmentation commonly include topical medications, microdermabrasion and mechanical grinding, but the results are not ideal. The first two are safe but very ineffective, so not many doctors choose this method. The latter grinding is strong and has some effect on some patients, but it is traumatic, risky and painful for patients. The main features are: 1. High trauma: The operation uses a high-speed rotating grinding wheel to shave off a layer of skin until the skin bleeds. 2, painful: the operation requires local anesthesia, the area of a large area also requires general anesthesia; post-operative bandaging, the area of a large hospitalization, seriously affecting work and life. 3, risky: because of the shaving off of a layer of skin, the wound bleeds and there is a risk of infection after surgery; if the healing is poor, not only can the discoloration not fade away, but also scar growth or pigment loss can occur. 4. Poor certainty of the effect: if the grinding is shallow, it cannot remove the pigmentation; if the grinding is deeper, pigment loss or scar growth will occur. With the development of minimally invasive scar treatment technology, there are new treatment methods for this group of patients, and Plasma, as a representative of the new generation of minimally invasive scar treatment technology, has been proven in the treatment of scar hyperpigmentation – with definite effect and safe minimally invasive. The advantages of Plasma are as follows: 1. Precise results: the inefficiency is almost zero as proven by clinical practice in large cases. 2. 2, safe and minimally invasive: the treatment process does not bleed, and the skin damage is small. The epidermis of colored sink is retained as a biological auxiliary material to cover the treatment area until new epidermis grows and fades away, which greatly reduces the possibility of infection in the treatment area. 3, less pain: minimally invasive treatment, no need to bandage after treatment, the patient’s pain is minimal. 4.Less hassle: You can go home after treatment, no need for hospitalization, and little impact on your work life. The efficacy of Plasma is not limited to this. While treating hyperpigmentation, it also corrects the scarring under the hyperpigmentation, making the appearance of the treatment closer to normal skin.
