If your nails are looking kind of grungy, take a fresh lemon, cut in half and just dig your nails into it,(not good if you have papercuts).
Then take the lemon and rub on your hands and elbows wait a few minutes, rinse (get a nail brush if you get the pulp underneath the nail and brush it out).
Rinse, apply lotion or lightweight oil (olive, almond, sesame), massage it in.
Your hands, nails, elbows will feel and look great! Best of all no chemicals, toxic smells, cheap & organic
