Iridescent refers to the opalescent, shimmering finish that beautifully reflects light to create the appearance of shifting colours. This finish is on-trend for 2022, and it appears that it's going to stay that way! It's a feminine, delicate touch on any manicure, and you don't have to be a professional to get a basic iridescent nail – you can get the finish at home with the suitable polish. OPI's Pearl of Wisdom is the essential iridescent nail polish.
