@france11We have active acne here. This is the most important thing to treat or you will continue to get PIE or redness and possibly scars. Please see a dermatologist.

Every patient I know who does glycolic and mandelic has to do many over a years time. They also use a retinoid or tretinorinnightly. You need a skin whitening cream, to work on the PIH also used nightly. They have ingredients such as azaleic acid, kojic acid, arbutin, licorice, etc...

Vitamin C serum can be helpful as well, ... wear sunscreen!

For stronger treatments see a doctor for pulse dye laser. Picosure / picoway can also help those with your skin type or other non-abaltive laser treatments for early scarring.

Discoloration issues are not scarring, ... work on your discoloration first and active acne.

Consult a few Dr's and choose the one you wish for pulse dye laser, there are many brands for hyperpigmentation, ... ask .
