How is dark patches on skin treated?

Darkening can follow acne, eczema, irritation, wounds, medicines, or repeated sun exposure. It can also occur with melasma, sun spots, acanthosis nigricans, or less common pigment conditions. A clinician examines the colour, border, texture, distribution, and timing before choosing treatment. A flat patch is approached differently from skin that is thickened, scaly, inflamed, or changing.

Light exposure can deepen several forms of pigmentation, including melasma and post-inflammatory hyperpigmentation. A diagnosis helps prevent harsh products from worsening irritation and creating more pigment.

Use broad-spectrum sunscreen and shade, and avoid picking, scrubbing, or fragranced products that sting. A clinician may recommend a pigment-targeting cream such as hydroquinone for a defined course, or another topical chosen for your skin and diagnosis. Procedures such as chemical peels or laser-based treatment require careful assessment because inflammation can make darkening more noticeable, especially in deeper skin tones. Treating an underlying rash, acne, or hormonal trigger is often part of the plan.

Arrange a dermatology assessment if a patch is new, rapidly changing, irregular, bleeding, painful, persistently itchy, or different from your other marks. Seek prompt medical care for darkening with widespread rash, facial swelling, breathing difficulty, or illness. These features need assessment rather than cosmetic treatment.

Ask what is causing the pigmentation, which ingredients are suitable for your skin, how long to use them, and what irritation should make you stop. Discuss whether a treatment could worsen pigmentation and how existing acne or eczema will be controlled.
