What should you know about hyperpigmentation knees and elbows?

Knees and elbows naturally have thicker, drier skin and experience repeated bending, leaning, and contact with clothing or surfaces. Persistent rubbing can make the surface rough and stimulate pigment after minor inflammation. Previous eczema, a healed scrape, or frequent kneeling may leave a darker patch. Colour can vary from tan to brown or grey-brown. A photograph cannot reliably identify the cause, especially when the skin is also scaly, itchy, or thickened.

Wash gently, pat dry, and apply a fragrance-free moisturiser while the skin is slightly damp. A product with urea or lactic acid may soften roughness; introduce one active product at a time and stop if it stings persistently. Limit leaning directly on elbows and use cushioning when kneeling. Protect exposed skin from sunlight, since ultraviolet exposure can maintain uneven colour. A dermatologist may consider a chemical peel, skin brightening treatment, or topical prescription after examining the patch.

Book an assessment if the patch appears suddenly, spreads, becomes markedly thick or velvety, or occurs with itching, pain, scaling, bleeding, or a non-healing sore. Also seek advice when similar darkening develops in several folds or when moisturising and friction reduction do not help. The clinician can check for dermatitis, psoriasis, infection, or other causes of pigmentation.

Ask what is causing the colour change, whether roughness needs separate treatment, which moisturiser or active ingredient is suitable, and how long to try it. Tell the clinician about new medicines, skin products, occupational kneeling, eczema, and any change elsewhere on the body.
