First, clean your nails and moisturize and shape. Gently push back the cuticle. Never cut it, it protects bacteria from entering your body. Nail polish is meant for nails, so pushin it back will avoid it from having an empty spot. Next, apply a base coat to prevent yellowing and smooth out ridges. Then, apply two to three coats of your color. The less the better. Lastly, apply a top coat for an extra gloss. Apply this to the tip too. This will prevent it from chipping since that is where it usually starts.
Just go to beauty shops and ask them for a good manicure and pedicure set. After getting the set, moisturize and massage clean hands and feet with your favorite ointments. To treat severely cracked heels, rub in Creative Nail Design's Spa Cucumber Heel Therapy. When you're done slathering, lock the moisture by covering your hands with spa gloves. You can as well cover your feet with a pair of soft cotton ankle socks overnight.
