Hello MildAcneMan,
Our best advice is to use The Regimen products. They will get you completely clear and will make your skin look nice and even toned and non-inflamed. Thats whats most important in order to prevent future hyperpigmentation and scarring. Make sure you use them diligently and you will get completely clear.
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.
Scarring is another story. Scarring is permanent. Be sure to be free of active acne before learning about or embarking on any scar treatment. You can read more about scar treatments here:
