Dark elbows can occur for several reasons, such as an accumulation of dead skin cells, hyperpigmentation, melasma, and certain skin conditions like eczema and psoriasis. And while these factors can affect any part of your skin, the elbows tend to be more vulnerable due to a lack of care and attention compared to other body parts. Fortunately, you can minimize and treat dark elbows by investing some time and effort into a good, overall skincare routine. For example, you can keep your elbow skin healthy and bright with daily cleansing and moisturizing. In addition, exfoliating the area twice a week can help you get rid of dead skin cells.
