What should you know about dermal pigmentation?

Pigment can collect below the surface after inflammation, sun exposure, hormonal changes, injury, or certain medicines. The colour may look brown, grey-brown, or slate-like, and the depth affects which treatments are suitable. A clinician examines the pattern and history rather than assuming every dark mark has the same cause. See [Dark Patches On Skin](/symptoms/dark-patches-on-skin/) for a symptom overview.

Use daily sun protection, seek shade, and avoid picking or repeatedly irritating the area. A dermatologist may recommend a carefully chosen topical plan, [Hydroquinone Treatment](/treatments/medical-dermatology/topical-hydroquinone-therapy/), [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/), [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/), [IPL Photofacial](/treatments/laser-and-energy/ipl-photofacial/), or [Picosecond Laser Treatment](/treatments/laser-and-energy/picosecond-laser-treatment/). The best option depends on depth, location, skin tone, and whether the trigger is still active. Introduce one active approach at a time and follow aftercare closely.

Book an assessment for a mark that is new, rapidly changing, irregular, bleeding, crusting, painful, or different from nearby pigmentation. Get advice if treatment causes blistering, marked swelling, increasing pain, or darkening that continues. Diagnosis matters because a changing pigmented lesion may need a different evaluation from cosmetic pigment.

Ask what may have triggered the pigment, whether it is superficial or dermal, what improvement is realistic, and how to protect the area from visible light as well as ultraviolet light. Mention pregnancy, breastfeeding, allergies, and previous reactions to creams or procedures.
