I still have acne, and I wanted to get rid of marks and scars, so I visited a dermatologist. So far, I have extruded, Shining Peel (6 times) + Fraxel (5 times) . The red acne marks are definitely getting better, and maybe it's because I took the medicine for less than a month in the beginning, so the acne is less. But the scar seems to heal really slowly.
