The next day after fractional laser treatment is day 1, and the first 5 days the treatment area is forbidden to use tap water for cleaning. Days 1-5 first dip the surface with a cotton swab dipped in saline every day (be careful not to wipe off the scab so as not to damage the new epithelium), and then apply Mepore moist burn cream 2-3 times a day. On the 6th day the treated area is nearly healed (the criteria for healing is that the treated area is dry, the scab is very thin and there is no ulcer) and normal washing can be resumed. After washing and bathing the scabs have not yet fallen off, you need to continue with the previous days’ operations. Scar medication will be applied (or applied) starting after the scabs fall off. After fractional laser treatment, there will be redness, swelling and oozing in the treatment area. These are normal phenomena, and the oozing will usually stop in 1-2 days. If there is still oozing or thick scabs after 2 days, or if the redness and swelling are still present after 1 week, please consult your assistant doctor for help. Sun protection is routinely required after fractional laser treatment to avoid discoloration of the treated area. However, in the case of discoloration and whitening of the scar, the treating physician will remind you that sun protection is not necessary depending on your condition, so please listen carefully. Please contact your physician assistant or come to the hospital if you are uncomfortable or do not understand after treatment. The above care is designed for most people, but because each person’s condition is so different, the treating physician may sometimes give special care instructions for individual cases, so please listen and take care of yourself. Medical technology is changing rapidly, so we will continue to adjust and optimize the above care according to the progress of technology and release it in time through the WeChat circle of friends and public numbers. To date, medicine has not been able to completely solve all scarring problems, but I and my treatment team will do our best and look forward to your success with our treatments.
