The skin discoloration that you are describing is something called post inflammatory hyperpigmentation. This is actually a normal healing reaction of the skin that occurs after inflammation or infection, such as acne
. Essentially what happens is that blood vessels and pigmented cells multiply in the area, leading to discoloration. Post inflammatory hyperpigmentation does not need to be treated, as it will gradually smooth out and fade over weeks to months.
What you do need to do is fix the root cause of the post inflammatory hyperpigmentation, which is the continuing acne break outs. If you do not have a daily acne care routine, you should start one. This could include, initially, a daily facial wash with a good facial soap, followed by the application of an over the counter acne care product containing either benzoyl peroxide or salicylic acid.
If this does not work for you, then you should see either your dermatologist
or your primary care doctor
. They will be able to indicate a more aggressive acne care regimen, which could include prescription strength benzoyl peroxide, topical or oral antibiotics, and other medications. With the help of your doctor, you should be able to get this acne under control!
