How to remove dark knees fast?

Knees commonly become rough and darker where clothing, kneeling, shaving, or repeated rubbing irritates the skin. Pigment can also remain after inflammation, such as a rash or injury; this is called [Post-Inflammatory Hyperpigmentation](/conditions/post-inflammatory-hyperpigmentation/). Colour alone cannot identify the cause, particularly when texture, itch, or redness is also present.

Cleanse without vigorous rubbing, then apply a rich, fragrance-free moisturiser to damp skin. Avoid kneeling directly on hard surfaces when possible and stop products that sting. Use sunscreen on exposed knees. A clinician may recommend a carefully selected topical treatment, such as [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/), or a supervised [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/). These options can irritate skin if used without a diagnosis, especially after tanning or when eczema is active.

Book a skin assessment if darkening appears suddenly, spreads, itches persistently, becomes thick or velvety, or occurs with a rash or pain. Prompt care is appropriate for warmth, swelling, drainage, fever, bleeding, or a non-healing sore. The clinician can look for inflammation before choosing a lightening plan.

What is driving the colour change? Is my skin barrier irritated? Which treatment is appropriate for my skin tone and texture? Should I avoid retinoids or a peel if I am pregnant, breastfeeding, or using other active products?
