The metal applicator is going to help with puffiness by helping to drain excess fluid from the eye area. The subtle iridescent pigment is going to help refract light, thus making the under eyes appear brighter if worn alone. This eye cream is appropriate for use under makeup for day-time. I don't recommend it for evening. I recommend something more repairative/preventative for evening. Watch my gratis haul video here https://www.youtube.com/watch?v=zaLg9fgwjUI&t=8s
