Are you struggling with dark elbows and knees which are not letting you wear skirts, shorts and sleeveless tops. If dark elbows and knees are causing you embarrassment, try to know what causes this problem and how to combat it. The skin of the knees and elbows get dark because the skin here is naturally thicker and there are no oil glands present in these areas because of which the skin in these areas is easily more prone to moisture loss and gets drier and rough. And if proper care is not taken to clean them, dirt can get trapped. Over time, dead skin cells get accumulated and darkened on these areas, which have been exposed to sun and dirt, and ruin the beauty of your otherwise beautiful and attractive legs and arms. If you have wasted a lot of money in buying products that have shown no expected result, try these effective home remedies.
