The difference between shellac and gel nails explained
Both types are quite durable, but the shellac nail is a patented form of polish that comes from the brand Creative Nail Design, so salons have to be CND-verified in order to use the polish. The formula of the polish itself is a half gel, half traditional polish hybrid which was developed by nail guru Jan Arnold (via Cosmopolitan). The combination of the gel and the traditional nail polish makes for a long-lasting and eye-popping product.
Gel nails, on the other hand, are formulated with only gel and aren’t exclusive to any brand or company. For both gel and shellac manicures, though, instead of drying like traditional polish does, the gel must be hardened under a UV light (via InStyle).
