IIID (3D) Foundation is foundation that uses highlighting and contouring to bring life and dimension to the face. IIID Foundation is different than your average highlight and contour because it is designed so that you only put each product where you want it, allowing you to only wear one layer of makeup. Most traditional foundations wash you out or give your face a flat, one-dimensional look, leaving you to go back and add more products to create dimension, whereas IIID Foundation allows you to just accentuate the dimension your face naturally has, saving you time and money!
