Some people are just more prone to hyperpigmentation unfortunately.

Here's more information. http://www.acne.org/faq.html#redmarks

and http://www.acne.org/ethnic-skin.html#hyperpigmentation .

same happens to me because i'm fair skinned. after a few months and acne.org aha lotion mine disappear.

It can take a couple months for them to fade away completely unfortunately. Its important to wear sunscreen everyday to prevent the sun from darkening the spots and prolonging the process. I'm currently using tretinoin 0.05% to clear my acne and it is supposed to help with hyperpigmentation as well.

I find that aloe, Apple cider vinegar, or Manuka honey also helps lighten my spots too.

If you treat your acne , you won't have to deal with dark spots in the first place.Do yourself a favor and give the regimen a try.
