While dark patches on elbows and knees is a common problem, luckily it is also a fairly easy problem to resolve. Quite often these dark spots are due to constant friction that occurs in those areas such as leaning elbows on a desk while typing or sitting on your knees while sitting on the floor.
Here are some easy ways to eliminate those dark spots and patches using products you probably already have in your home.
Try Moistuizer Lotion
Dark spots are usually caused by the dry skin in those areas. Try applying moisturizer to elbows and knees 2 to 3 times a day. If you work in an office, keep a small bottle of moisturizer on your desk to remind yourself. Another good thing to try is to moisturize as soon as you get out of a shower while your skin is still moist and pores are open and before bedtime to give it time to sink in.
Exfoliate With a Scrub
Another way to get rid of the dead skin on these over-frictioned areas is to gently remove it with an exfoliating scrub. Gently apply the scrub in a circular motion over dark areas for a minute or two, rinse off and immediately apply a moisturizing lotion. You should see an amazing difference in just a matter of a few days.
Use A Lemon
Another great way to lighten the dark patches in these areas is to use a good old fashioned lemon. For elbows, cut a lemon in half and simply place each elbow in each half and let sit for approximately 15 minutes. For knees, simply rub the lemons on each knee for the same amount of time. Then gently rinse off with a damp towel. If a fresh lemon isn't handy, lemon juice will work as well. Liberally apply lemon juice to area (you can place juice in small bowls and let elbows soak) or apply with saturated cloth to knees.
Skin Bleaching Lotions
For extremely stubborn patches you can also try a gentle skin bleaching lotion. These lotions can be found in most major drugstores and chains. Simply follow the manufacturer directions and you should see a change is as little as a few applications.
