The skin around the knees tends to darken and dry out more than other parts of the body due to frequent bending and stretching. If your knees are darkened, you can use natural exfoliating mixtures to lighten the skin or purchase lotions and creams that treat dry and darkened skin. In some cases, darkened knees could be a sign of an underlying condition, in which case you should consult a doctor.
Steps
Moisturize and Exfoliate at Home

Make a knee exfoliation scrub using sugar and olive oil. Mix 1/3 cup (80 ml) of olive oil and 2/3 cup (150 g) of white sugar in a bowl until well combined. Rub the mixture onto your knees with your hands. After scrubbing for about 30 seconds, leave it on for an additional 5 minutes before rinsing off with water.
- This mixture will remove dead skin cells, helping your knees become lighter and brighter.

Mix baking soda with lemon juice to create a natural skin brightening paste. Combine equal parts of baking soda and lemon juice in a small bowl, stirring until it forms a paste. Rub the mixture onto your knees for about 1 minute, then rinse off with water.
- Baking soda and lemon juice are both natural bleaching agents that work effectively for many people, and the gritty texture of the baking soda helps exfoliate the skin. Both ingredients can gradually help lighten darkened skin.

Use almond oil as a knee moisturizer. Apply about 1 tablespoon of almond oil onto your knees each night. Be sure to cover your knees with the oil and wrap them with a cloth or bandage overnight.
- Almond oil is also a natural whitening agent and helps keep the skin moisturized, making it softer and less prone to darkening.

Apply an aloe vera mask if your knees have scars or sunburn. Mix ½ cup (120 ml) of unsweetened plain yogurt with 2 tablespoons (30 ml) of fresh aloe vera gel. Use a spoon to apply the mask to your knees and leave it on for 15-30 minutes, then rinse off with water.
- Numerous studies have shown the scar-healing properties of aloe vera.
- To extract aloe vera gel from the plant, simply cut a leaf from the plant, split it open, and scoop out the gel inside.
- If fresh aloe vera gel is not available, you can purchase pure aloe vera at many pharmacies and supermarkets.

Use a loofah or rough sponge to scrub your knees in the shower. If you prefer not to use an exfoliating mixture, you can use materials such as a loofah or rough sponge to remove dead skin cells. These items can be bought at supermarkets, pharmacies, or beauty stores and used while showering. Scrub each knee for 30 seconds.
- Physical exfoliation methods using materials like loofahs, sponges, or soft pumice stones are commonly used to treat symptoms of psoriasis and other dry skin conditions.
Apply Creams and Lotions

Apply lotion to your knees daily to reduce dryness. Use a moisturizing lotion every morning and evening, focusing on your knees. Look for lotions that contain waxes and oils, as they form a protective barrier on the skin to lock in moisture.
- Dry skin is one of the most common causes of skin darkening all over the body.
- If you stop moisturizing regularly, dark spots on your knees may return.

Apply sunscreen every day to prevent sun damage and pigmentation issues. If you have darker skin, your knees might be more susceptible to sun damage and scarring. Make sure to apply sunscreen to your knees every morning, especially when wearing shorts or skirts. This is recommended by many experts.
- While it's difficult to reverse pigmentation or scars, you can prevent further damage by regularly applying sunscreen.
- In some cases, sunscreen may even fade dark spots!

Use chemical creams or gels to treat darkened knees. If you have persistent dark spots, look for skin-lightening creams or gels containing 2% hydroquinone. Apply the cream to your knees daily for 4-6 weeks for optimal results.
- Hydroquinone can cause irritation for those with sensitive skin. If you experience a burning or stinging sensation when applying the cream, rinse your knees with cold water immediately.
- Avoid using whitening creams for more than 6 weeks as they can irritate the skin and damage its outer layer. Long-term use of skin lighteners has been linked to certain types of cancer.
Address underlying issues

Increase your water intake to improve skin hydration. If you suspect your dark knees are caused by dry skin, try drinking more water! In general, aim to drink at least 2 liters of water daily for healthy, glowing skin.
- If you don't see results by increasing your water intake, consider using a natural remedy or applying moisturizer in addition to drinking more water.

Visit a dermatologist to diagnose pigmentation issues or skin conditions. If you've tried multiple methods to lighten the skin on your knees without success, it's time to see a dermatologist. The doctor will examine your knees and run tests to determine the cause of the discoloration.
- Be sure to inform your doctor about the treatments you've already tried to lighten your skin.
- The dermatologist can explain why your knees are darker and suggest stronger treatments to lighten the skin.
Get tested for diabetes if you have persistent dark spots on your knees. Sometimes, undiagnosed or untreated diabetes can cause dark patches to appear on the knees or shins. If you have spots that won’t fade, visit your doctor for a diabetes test.
- This condition is known as 'diabetic skin atrophy' and is often confused with age spots.
Advice
- Remember that dark spots on your knees are completely normal, and many people have areas of darker skin all over their body.
