Laser scar removal is mainly divided into stripping laser and non-stripping laser. For concave scars, exfoliating laser can be treated with lattice carbon dioxide laser, but the coverage rate of ordinary scars is relatively small, so it is impossible to completely cover the scars.
Non-stripping laser can also be used for scars, such as pulsed dye laser irradiation, mainly for early scars, such as hyperplastic scars, but it can not alleviate the scars that have already formed.
Harm and effect of laser scar removal Laser scar removal has a good effect, which can improve the appearance of scars to some extent. If the parameters of laser scar removal are set reasonably and the postoperative recovery is smooth, it is basically harmless, but if the postoperative care is improper, the following hazards will occur.
1. If the selected energy parameter is too high, it may cause so-called scald reaction to the treated tissue, leading to some proliferative consequences.
2. There may be pigmentation, even hypopigmentation's phenomenon, but this situation is usually temporary and will fade away after a period of time.
How many times does laser scar removal need? Laser scar removal takes 8- 10 times, depending on individual circumstances.
The main principle of laser scar removal is to destroy the fibrous scar tissue at the scar site through the energy generated by laser, so as to achieve the effect of diluting the scar.
Different types of scars have different treatment time. If the scar is shallow, such as scratches, the treatment time is short. After 3-5 times, the scars and surrounding tissues are blurred, and the treatment time of concave or convex scars is longer, which takes about 8- 10 times.
Tips Because the laser has a certain thermal effect, it will stimulate or even damage the skin tissue around the scar, so avoid getting wet and scratching.
4 Precautions after laser scar removal 1. After laser scar removal, the skin lacks protective function. Pay attention to sun protection, light diet, avoid drinking, avoid spicy food, supplement vitamin C and high-quality high protein, and drink plenty of water within one month after operation.
2. The problem of improving early scar or hypertrophic scar is generally treated by pulsed dye laser and photon rejuvenation. After photon rejuvenation, normal life will not be affected, but pulsed dye laser can't touch water.
