A roll-on for puffiness, tired eyes, and the look of dark circles. Built around caffeine and a peptide. The cool steel ball applies it; the formula does the rest. 15 ingredients. Most eye products run two to three times that with silicones that blur the look for an hour, fragrance and dye you don't want near your eye, stacked preservatives. This is the actives that work: caffeine for puffiness, a peptide and two forms of hydration to firm and smooth, vitamin C to brighten. Caffeine constricts the surface vessels that cause puffiness and shadowing. Palmitoyl Tripeptide-5 supports firmer skin. Sodium hyaluronate and panthenol hold moisture where skin is thinnest. The cool roller takes down puffiness on contact.
