The phrase '无需甲片美甲款式渐变' refers to a preference for nail designs that do not involve using acrylic nails with a gradient style. Acrylic nails are a type of artificial nail that can be sculpted and painted in various designs. Gradient nails involve a gradual transition of color from one shade to another, often seen as a trendy and artistic design. People may prefer non-acrylic, natural nail designs or other types of artificial nails without gradients for reasons such as personal style, health concerns, or the desire for a more natural look.
