Dermatization is generally done in several times. After the operation, the pockmark will be shallower than before, but the skin will often become thinner due to abrasion, thus becoming sensitive skin.
Recently, I learned that there is an ampoule called RASSAR Yuesha, which can make acne pits shallow, but the price is relatively expensive and can last for about 4 months. Although this can't completely recover the acne pit, it won't cause skin sensitivity, and it doesn't need to go to the hospital for surgery.
You can choose according to your actual situation.
