Hello. Is there something I can do to improve scars that are relatively small and superficial and not too deep? (In comparison to very pronounced scars.)

I have a lot of small scars (and 3 or 4 bigger ones from bigger and deeper acne). And I have some around the mouth which are the ones that bothers me the most. Even on the limit with the lips - and a couple of these even left darker little spots on the lips themselves.

I am not familiar with current treatments for scars. Once I read that it is easier to improve deep scars.

And if there is a treatment, my doubt is if it is really effective, if it truly softens the scars permanently, or if it is only a temporal illusion due to peeled superficial skin or temporal swelling of it.
