Hi Thismacne,

The Regimen products will promote healthy looking skin and allow your dark marks to heal over time. The dark marks or scars on your skin are called erythematous macules which will fade away after six months or more provided that you do not have any more acne breakouts in the future.

However, the hyperpigmentation itself can take several months or longer to fade. To speed this process you can add Acne.org AHA+ which will help increase skin cell turnover and allow your acne marks to fade faster. But nothing will help hyperpigmentation fade extremely quickly. Its only time that can do that. Remember that hyperpigmentation are not scars, however, and will fade with time.
