How to remove darkness from elbows and knees?

Elbow and knee skin is exposed to bending, pressure, rubbing, and dryness. Repeated irritation can trigger extra pigment, while a thick rough surface can make the area look darker. Pigment may also remain after a rash, bite, or minor injury; this is called Post-Inflammatory Hyperpigmentation. A clinician should examine skin that is rapidly changing, thickly velvety, painful, or itchy rather than assuming it is cosmetic.

Use a fragrance-free moisturiser after bathing and whenever the skin feels tight. Avoid scrubbing brushes, harsh bleaching mixtures, and picking at flakes, because irritation can deepen pigment. Reduce leaning on elbows and kneeling on rough surfaces, and use comfortable clothing. Apply broad-spectrum sunscreen to exposed areas. If home care is not enough, a dermatologist may discuss Topical Retinoids or a Chemical Peel after checking your skin type, cause, and sensitivity; these treatments can irritate and need tailored instructions.

Arrange a dermatology review if the colour change spreads, develops suddenly, becomes thick or velvety, or comes with persistent itch, pain, scaling, bleeding, or sores. Seek prompt care for signs of infection such as increasing warmth, swelling, pus, or fever. Bring a list of products and medicines, including anything recently started on the area.

What is causing the darkening, and is there irritation or a skin condition to treat first? Which moisturiser or active ingredient suits my skin? Would a prescription treatment or procedure be appropriate, and how can irritation be reduced?
