A multi-tasking liquid luminizer can be used alone as a highlighter, mixed with moisturizer for a beautiful glow or added to foundation for a dewy, more luminous finish.For high shimmer: Apply directly after foundation. For subtle shimmer: Mix with foundation and apply to face. For a sheer look: Mix with moisturizer and apply to face. I have used some of this but I have stopped wearing makeup. There is just a slight bit gone. About 1/8" from the top of the bottle.
