Swelling of scars after rolling
The most logical explanation is that after you roll, your skin swells due to inflammation. This temporarily makes your scars less visible. Once the swelling settles.... scars come back. A better way to explore and understand scars is to know what type of acne scars you have, and how to best treat them. Video below explains in great detail. All the best, Dr Davin Lim. Brisbane.
