How is hyperpigmentation diagnosed and treated?
A dermatologist can diagnose the cause of your hyperpigmentation. They will request your medical history and give you a physical exam to determine the cause. In some cases, a skin biopsy can narrow down the cause.
Topical prescription medication can treat some cases of hyperpigmentation. This medication usually contains hydroquinone, which lightens the skin.
However, prolonged use of topical hydroquinone (without any breaks in use) can cause darkening of the skin, known as ochronosis. So it’s best to use topical hydroquinone only under the care of a dermatologist so that they can properly guide you on how to use the medication without any adverse effects.
Using topical retinoids also assists with lightening dark spots of the skin.
Both of these medications can take a few months to lighten darkened areas.
Home care sometimes includes over-the-counter medications that may lighten dark spots. These medications don’t contain as much hydroquinone as prescription medications.
