There are multiple options that are available to you to help you deal with your acne
scarring. It would be best to discuss this with your dermatologist
before you begin, as treatments options depend on the extent of scarring and hyperpigmentation as well as cost considerations.
If you are just interested in dealing with hyperpigmentation, you may find that mild chemical facial peels or dermal microabrasion, two treatments that you can get in many respectable salons. These treatments work by removing dead skin and toning up the underlying skin; often they can give some improvements in skin color as well. If these treatments do not work for you, then there are multiple skin lightening creams that are available by prescription from your dermatologist.
If, on the other hand, you are trying to deal with both hyperpigmentation and underlying cratering and other forms of scarring, then you will probably need a more in depth treatment. Laser treatments are one popular option. These work by stimulated skin turnover and collagen remodeling and range in intensity from mild sunburn to extensive stripping of outer skin layers. The more intensive treatments are more effective, but also require downtime and have the potential for more complications.
