Detailed answer

To improve uneven skin tone on your knees and lower legs, exfoliation and moisturization are key. Start by exfoliating the skin on these areas at least twice a week with a gentle scrub or a scrubbing brush. This will help remove dead skin cells and promote cell turnover. After exfoliation, apply a moisturizing cream or lotion that contains ingredients like glycerin or hyaluronic acid to help hydrate and nourish the skin. Regularly moisturizing will promote a smoother and more even skin tone. Additionally, protect your skin from excessive sun exposure by applying a broad-spectrum sunscreen with an SPF of 30 or higher whenever you are outside. UV rays can darken and damage the skin, exacerbating uneven skin tone. Lastly, consider using skin lightening products specifically formulated for the body that contain ingredients like hydroquinone or kojic acid. These ingredients can help lighten dark spots and even out skin tone when used as directed. Remember to always patch test any new products and consult with a dermatologist if you have any concerns or underlying skin conditions.
