PIH usually heals over time without treatment, but it can take up to a couple of years. Some spots may never fade. Treatments include OTC creams, prescription medications, and in-office procedures.
How long does pigmentation take to go away?
Keep in mind that hyperpigmentation does not always fade. Even with treatment, some hyperpigmentation will be permanent. Without any treatment at all, it can take 3 to 24 months to see improvement. It really depends on the severity of darkened skin and how much the hyperpigmentation covers.
Can hyperpigmentation go away by itself?
Hyperpigmentation acne may fade over time, but if the original spots were deep, it may be permanent. Although some topical and surgical therapies can speed up the fading process, it can take several months to years.
