Hyperpigmentation From Sun Exposure: Treatment Options

Ultraviolet light can stimulate pigment production and make existing marks look darker. Freckles, sun spots, and uneven patches may appear on the face, hands, shoulders, chest, or other exposed areas. A dermatologist considers the shape, colour, distribution, and history of the marks. Not every dark patch is caused by the sun, so a new or unusual lesion should be examined rather than treated as a cosmetic concern alone.

Use broad-spectrum sun protection on exposed skin, reapply as directed on the product, and add shade, clothing, or a hat when practical. Avoid picking at irritated areas. After assessment, options may include a prescribed topical treatment, chemical peel, IPL, or a pigment-targeting laser. Results depend on the type of pigment and how the skin responds; excessive irritation can deepen pigmentation, especially in darker skin tones.

For background on [Dark Patches On Skin](/symptoms/dark-patches-on-skin/), see [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/) and [IPL Photofacial](/treatments/laser-and-energy/ipl-photofacial/).

Book a skin assessment for a spot that changes in size, shape, colour, or surface, or one that bleeds, crusts, itches persistently, or fails to heal. Seek prompt medical advice when several patches appear quickly or when pigment comes with a persistent rash. Do not start a strong lightening product on an unexamined changing lesion.

Ask whether the pattern fits sun-related pigmentation, how much sun protection is needed for your routine, and whether a topical treatment, [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/), or [Hydroquinone Treatment](/treatments/medical-dermatology/topical-hydroquinone-therapy/) is appropriate. Ask how irritation will be managed.
