Acrylic and hard gel nails are artificial nail enhancements cured under UV or LED light. Acrylic nails are made with a liquid monomer and powder polymer, while hard gel nails use a thick gel substance. Acrylics are ideal for longer, sculpted nails, while hard gel is best for shorter, natural-looking nails. Gel nail polish is also cured under UV or LED light and is used for a variety of nail designs. Gel nail polish is used without artificial nail enhancements. The choice comes down to personal preference and lifestyle.
