I actually received a sample size tub of this and decided to give it a try. This has got to be the best, most refreshing Eye Balm / Serum that I have used by far. The balm goes onto your skin so smoothly and gets absorbed really quickly. Seeing that you only use a teeny bit each time, my tiny tub actually lasted me an entire month. I saw effects after about 2 weeks of regular use each evening before bed. My eyes were less puffy in the mornings, my eyes seemed more vibrant. Fewer laugh lines are a definite plus! It also reduced dark circles around my eyes caused by stress and fatigue. The price is quite steep, but I think it is worth it because a full size tub will last a long time.
