How can I get rid of this punch biopsy scar? (photos)

This spot can be improved with a combination of lasers, Aerolase, microneedling/prp, skin lightening, peels, and skin care. Sun protection is essential. I recommend getting a formal evaluation with an acne scarring expert. Best, Dr. Eme

Thank you for sharing your question.  Though nothing replaces an in-person examination, after a year's time a surgical scar revision is likely your best option at obtaining a better result.  One that leaves you with a fine line scar without the hyper pigmentation seen in your picture.  See an ASPS board certified plastic surgeon in consultation for the best treatment advice.
