subject: Improve Skin Tone and Texture of Skin [print this page] Acrylic nails are yet another means of keeping on top of those aging years. Some people say that a woman's age can be judged by her hands, but if you have acrylic nails that is no longer possible. Acrylic nails can be worn over natural nails. If they are bumped out of place, it can create a moist space where fungi can grow and blacken the natural nails. But it they are kept on properly, all is usually well. Rarely, a person will have a problem with contact dermatitis, causing redness and peeling. In this case the acrylic nails should not be worn.
