There are many such marks on the skin which may appear to be like scars but are not in reality. They may be pigmentation of some other kind but not acne scars.

Macules- they are reddish and flat spots that are formed when an acne lesion is in its last and the most inflamed stage. A macule stays on after the acne lesion has been treated or flattened. This macule marks the place of the lesion; it stays on for a few weeks to about 6 months and finally wears off, unlike a real scar, which does not disappear.

There are other forms of marks on the face like post pigmentation scars which is most common in people with a darker skin tone, but shows mostly in people with light skin. This happens when the affected area of skin heals and is left discolored. It requires prompt attention and visiting a dermatologist early is beneficial. It is most vulnerable in sun and may persist up to a year or 18 months. There is a treatment that can be done only under sterile medical conditions called chemical peeling which stimulates the process of treatment.

Thus, we now know that there are other marks also that can be mistaken for scars, which are actually marks which heal in time without a trace.
