Of course, you will feel some of it. Acne scar laser treatment can be compared to small, warm pinpricks on the skin. After the treatment, the skin glows and feels tight for a few hours. The chemical peels cause a burning sensation that goes away after 10 to 15 minutes. About two days after the peel, the skin may flake a little. Good news; your new skin is just emerging that way. Microneedling is also not very painful, but can be very sensitive on the forehead and around your eyes. The after-treatment cream - with which your skin is rubbed - fortunately works well soothing and calming.
