I too have used the product that Cathy told about and I wanted to share another beauty hint about nails. I pierced some Vitamin E capsules and squeezed the oil in a small container, like a pill box.
I then added an equal amount of hand cream and mixed it well. I use that on my nails and cuticles every night and it's wonderful. My nails and cuticles are in such good shape!
I also use straight Vitamin oil on really dry skin spots and my DH uses it on ingrown hair sores from shaving. It's great on wrinkles too.
