hi, there are multiple treatment options available to tackle acne
scarring. One can go for peels, microdermabrasion
, dermarollers(microneedling of scars
) and even Lasers. What will suit to your needs, depends on the kind of scars you are having that is whether they are superficial or deep scars. As far as darkening of ceratain body areas are concerned, you should protect yourself from sun exposure, use a good sunscreen and can go for peeling sessions to lighten the darker areas. Hope that solves your query.
