When you mention about the MARKS do you mean the dark pigmentation OR the depressions in the skin surface which occur when big acne pimples heal. For the treatment of the pigmentation marks creams can be used. For the treatment of the depressed scars procedures are required to get an improvement. There are options like hyaluronic acid filler or subdermal fat transplant which can be done for the holes if they are slightly bigger. But the very tiny depressed scars would require either laser treatment or micro needling. For the holes some kind of procedural intervention definitely be needed. Get an online consult privately with pictures or meet a dermatologist directly for a proper evaluation of the condition. Hope this was helpful.
