How to get rid of dark elbows and knees

Have you ever noticed that the skin on your knees and elbows appears darker than the surrounding areas, even though you don’t feel any discomfort This common phenomenon can be caused by a variety of factors.

Causes of dark knees and elbows

Friction and pressure: Think about how often your elbows and knees come into contact with your clothing and other surfaces (such as tabletops).This constant rubbing can lead to thickening and darkening of the skin as a protective measure.

Sun exposure: Our knees and elbows often bask in sunlight without the protection of clothing. UV rays stimulate melanin production, resulting in darker patches on these exposed areas.

Dry skin: When our skin lacks hydration, it can become rough and dull, also accentuating any existing discoloration. The frequent movement and exposure of knees and elbows make them particularly prone to dryness.

Skin conditions: Inflammatory skin conditions like eczema and psoriasis can exacerbate the darkening of knees and elbows.

Excess melanin in this case is an aesthetic concern and is mostly harmless, however if the skin gets itchy, flaky, or starts burning for no clear reason, check in with your doctor/dermatologist.

How to treat dark knees and elbows

Use skin-smoothing ingredients: Look for topical products containing ingredients like lactic acid and urea. In most cases, treatment with lactic acid 12 or urea cream over 3 to 6 months is at least partially effective¹. These agents help soften and exfoliate the thickened, darkened skin, promoting a smoother texture and more even tone.

How to prevent dark knees and elbows

Minimize friction: Be mindful of activities that involve frequent rubbing or pressure on your elbows and knees. Consider wearing protective clothing or using pads to reduce friction and minimize further darkening.

Sun protection: Don't forget to apply sunscreen to your elbows and knees before stepping out into the sun. Reapply it throughout the day and seek shade when possible to shield your skin from harmful UV rays.

Regular moisturization: Consistent moisturization helps maintain the skin's protective barrier, thus decreasing the likelihood of dark patches forming due to inflammation.
