Skin type-medium. Age-19. Gender-female.
Thank you for your question and photograph. It's difficult to evaluate your skin through this type of forum, but from what I can see, it looks like you have atrophic scarring (indentation). Treatment modalities that injure the skin causing subsequent collagen formation works best, such as laser therapy, microneedling, injections with fillers, etc. I highly recommend you consult with a board certified dermatologist or plastic surgeon to have your scar evaluated and to discuss appropriate treatment options. Take care and good luck.
