After wearing a mask all the time and using cosmetics incorrectly, I had a lot of acne on my face, so I was looking for a dermatologist. I went to Renewme Dermatology because they said they only had specialists. I had a consultation and recommended a acne mark treatment program (3 times of scaling + 3 times of Excel V or Gentle Max Pro). + I paid for 3 laser toning treatments and have now received the 2nd treatment. First of all, many of the red marks are gone, but the brown marks remain. If you are planning to get treatment for red acne marks, Excel V is recommended. For brown marks, it would be good to use Secret Laser (at a cheaper place). Up to 3 treatments. I don't think it will go away completely even if I get it, but I'm satisfied so far. However, it's expensive so I don't think I'll be able to get it until the 5th time.
