1, in the treatment before, and the doctor fully communicate is the most important. Because of the fear caused by the lack of understanding, many people who need to be treated are afraid of plastic surgery, in fact, it is often necessary to talk with the doctor and these concerns will be relieved. In order to avoid medical disputes, with the doctor to reach a consensus is also necessary, their own spot belongs to which kind, probably need a few courses of treatment, etc., should be confirmed. 2, before the treatment, there are no special things to pay attention to. The beam of the spot removal laser is struck down little by little. The dermabrasion laser is done in a sweeping motion. The laser hits down feels like being bounced by a rubber band and there is a little pain. However, the pain is reduced after anesthesia. After the laser treatment, it is normal for the skin to be red and swollen due to the energy being directed at it, and sometimes there may be some slight bleeding. However, it will subside soon. Anti-inflammatory cream should be applied every day, and the wound will slowly form a scab that will peel off in about a week. During this process, you should pay attention to keep clean, and avoid sun exposure, otherwise it is easy to cause temporary hyperpigmentation (temporary hyperpigmentation needs 1-6 months to fade). If the pigmentation has not all faded, the next treatment can be carried out after about 3 months. 3. Many people are worried about the after-effects of the treatment. In fact, if the treatment is performed by a professional doctor, the possibility of problems is not very high. Generally speaking, it is easy to have the problem of darkening pigment or whitening pigment, so the safer way is to carry out experimental treatment. First hit a few points with different energies and observe after a few weeks to see which energy is most suitable for treatment. Laser hair removal is prone to burn the epidermis due to too much energy or ineffective hair removal due to insufficient energy. 4, basically most of the laser surgery, do a week after the recovery, but the new skin will inevitably have red pigment, about 2-3 months will fade, normal! After surgery must not be attacked by ultraviolet light, ultraviolet light definitely helps to enhance the active capacity of melanin, the best first 1, 2 months to try to avoid sun exposure, even if fully recovered, when you go out, you should also apply sunscreen to reduce the chance of re-emergence of the spot and the active capacity of pigmentation. 5, eat more vitamin C food can help inhibit the growth of pigment cells and strengthen the growth of collagen in the skin, so that the new skin is more beautiful. Usually a week after laser surgery will have a scab (scorched) phenomenon, do not tear off their own hands, otherwise there will be a seal!
