The MARS Cosmetics Illuminati Base is an illuminating and dewy primer that can be used as a primer or liquid highlighter. It contains water, glycerin, mica, mineral oil, ceteth-20, macadamia ternifolia seed oil, tocopherol, niacinamide, ascorbic acid, panthenol, xanthan gum, methylparaben, and fragrance. The product is available in different shades such as "Gold Beam" and "Pink Beam," each with its own base and sheen. The primer is designed to provide a natural, radiant glow to the skin, and it is loaded with light- reflecting micro-particles. Some of its features include the ability to blend beautifully, leave the skin with the perfect shine, and have luxe packaging. However, it's important to note that the product contains tiny shimmer particles that can be visible on the bare skin if used without foundation
