What Does Hydroquinone Treatment Treat?

Hydroquinone reduces pigment production in treated skin. It may be prescribed for [Melasma](/conditions/melasma/), [Post-Inflammatory Hyperpigmentation](/conditions/post-inflammatory-hyperpigmentation/), or other diagnosed areas of excess colour such as [Perioral Hyperpigmentation](/conditions/perioral-hyperpigmentation/), [Periorbital Hyperpigmentation](/conditions/periorbital-hyperpigmentation/), and [Dark Underarms](/conditions/dark-underarms/). It is not a general-purpose product for every dark patch. The cause, skin sensitivity, location, and risk of renewed pigment all influence the plan.

Apply only to the areas and schedule advised by your clinician, avoiding eyes, lips, and irritated or broken skin. Use gentle skincare and daily sun protection, because ultraviolet exposure can deepen pigmentation and reduce progress. Do not combine it with several irritating products without guidance. Stop and arrange a review if burning, marked redness, swelling, blistering, or unusual blue-black darkening develops. Keep the container away from children.

Have a new, changing, bleeding, or uneven dark patch examined before using a lightening medicine. Seek prompt care for severe swelling, blistering, intense pain, or a rapidly spreading reaction. If pigmentation continues to worsen or returns quickly, the underlying trigger may need treatment and the regimen may need reassessment.

Ask whether the patch is suitable for treatment, how to protect the area from sunlight, which products to avoid, and when to pause or review the course. You can also discuss [Hydroquinone](/materials/hydroquinone/) and whether [Dark Patches On Skin](/symptoms/dark-patches-on-skin/) needs a diagnostic assessment first.
