Pink & White refers to the colors used in a nail enhancement. When you get a set of Pink & Whites, it is normally done in acrylic. Acrylic comes in many, many different colors. Pink & White full sets refer to the pink being at the base of the nail, and the white being the tip - or the extension of the nail. This can be done the easy way by using white plastic tips glued to your natural nails and then the technician will apply clear acrylic over that to provide strength to the nail extension. Or, the white can be 'sculpted' on. Sculpting is an advanced technique where the technician applies forms over your fingertips, and uses the form to sculpt the entire extension.No plastic tips are used in this method. It gives a much more realistic looking final result, and is more durable and more realistic looking than using tips. And last, Nail Pro & Spa Pink & White has more to offer: Gel will be applied as a finishing touch!
