I would use a combination of Botox, fillers, and fractional lasers to help smooth out these scars on the glabella.
Combination of filler and BOTOX, this will give a good improvement. I suggest Botox first, wait 2 weeks, then filler. High risk area as lots of blood vessels, so see a Board Certified Specialist. Dr Davin Lim. Brisbane. Australia.
This area can be treated with a combination approach to get improvement. I suggest seeing an expert. Best, Dr. Emer.
