I believe that every beauty lover would like to achieve the most perfect result through treatment, and of course, as doctors, we would also like to see this. The treatment of nevus of Ota is not only a doctor’s job, but also requires each treatment patient to cooperate with the doctor’s guidance to do a good job of post-operative care in all aspects of the prognosis. So, what exactly do you need to do after surgery? 1.No water on the traumatic surface for 7-14 days after the treatment of nevus of Ota; 2.Apply anti-inflammatory cream locally for 4-6 days, 1-2 times a day to prevent secondary infection, which may lead to scars; 3.After the treatment of large area, local swelling or a small amount of blisters are normal, which will gradually subside after 6 hours. This is normal and will gradually subside after 6 hours. The scab will be formed on the wound surface and will fall off naturally in 7-14 days, do not forcefully peel it off to avoid scarring; 4. Pay attention to sun protection, otherwise it will produce transient pigmentation; 5. After treatment, pigmentation is a slow biological process, generally 1-3 months, a few cases can be as long as 9 months, be patient, adhere to treatment; 6. It is recommended that when you go out, you should shade and apply sunscreen; sunscreen is especially important in summer, and it is recommended that you use a high SPF; 7, for those who are not well protected from the sun, or those who are prone to pigmentation, after 15 days, pigmentation will gradually appear on the fresh tissue, and around 30 days, the pigmentation will be most obvious. After 3 months, most of the pigmentation will fade away, and the complete fading period will be more than 3-6 months. During the period of pigmentation, you can also take VC orally, which can effectively prevent and subside pigmentation; 8. The fresh skin after debridement is relatively delicate, so you should not use stimulating cosmetics, such as certain products with therapeutic effect of spot removal, wrinkle removal products, whitening products, etc. Try to use non-stimulating skin care products, such as Johnson’s baby cream, Vaseline ointment.
