Acne scars aren’t actually scars. They’re this thing we refer to as post inflammation pigmentation. In short acne scars are basically dark spots (think of it like spots you get from the sun, but a little different) and because of this you cannot use a rosehip oil, vitamin e oil, etc to fade them and treat them as scars. Instead you need to treat them as discolouration.
Acne is a very common skin disorder which has become problem for all ages.
