Acrylic nails and BIAB (Builder in a Bottle) are popular choices for nail enhancements. Acrylic nails are made by combining a liquid monomer with a powder polymer to create a hard layer over the natural nail. They are known for their durability and versatility in terms of shape and length. On the other hand, BIAB is a soak-off builder gel that provides strength and structure to the nails without the need for traditional extensions. It's a great option for those looking for a more natural nail look with added strength. Both acrylic nails and BIAB offer a way to achieve beauty.
