Sorry for late reply. Are you talking about the scar after a person gets a bad case of acne and then leaves a reddish spot on the face? There are many brands of skin products in the market, but to be sure, avoid products that sound like they are sold on Home TV Shopping. These rarely work and rely on sensationalism and promos. If something sounds too good to be true it probably is.
Your dermatologist might recommend procedures like dermabrasion ("magpaderma") which uses a rotating wire brush or spinning diamond instrument to wear down the surface of the skin. As the skin heals, a new, smoother layer replaces the abraded skin. It may take a bit longer for skin to heal using dermabrasion  usually between 10 days and 3 weeks.
One form of treatment is laser resurfacing, which can be done in the doctor's or dermatologist's office. The laser removes the damaged top layer of skin and tightens the middle layer, leaving skin smoother. This can take anywhere from a few minutes to an hour. The doctor will try to lessen any pain by first numbing the skin with local anesthesia. It usually takes between 3 and 10 days for the skin to heal completely.
There is also treatment for milder cases like chemical peels (using chemical substances) and microbrasion.
What you should not do is to BULLY your acne scar like pinching, rubbing or scratching at it. You might make it worse.
