Will a Dermaroller Work Well on Atrophic Scars(as Pictured Below)

Thanks for your question. Indeed, dermaroller can work quite well on atrophic scars as it induces natural collagen synthesis and tissue remodeling. However, derma stamp would be more appropriate for scar treatment on your forehead because it can be more precisely applied. Combining the treatment with retional topical preparation will also help as it stimulates cellular turnover.
