Hi, 1 yr ago I accidentally went head first into a metal roadside barrier and had a v. deep cut through my eyebrow, approx 4.5cm long. When I frown or lift my eyebrow a dent/crevice shows and this movement feels restricted. Above my brow on the inner side my forehead is more raised/puffy so I look like i'm frowning a bit when i'm not. The scar surface is bumpy so it shows esp in light. What treatment approach is recommended and what are the expected outcomes in improving my scar?
