Natalie SorbentoOmiera Labs Illumizone Dark Circles Under Eyes Serum (0.5 Fl.Oz)Verified PurchaseI've tried several products for the dark circles under my eye, some don't work and some work but after continuous use of 3 month. A friend told me about the Illumizone. I felt a little bit of a difference in the first day or 2 but in a week my coworkers started to notice the difference and in 2 weeks my dark circles were almost gone. I'm still using it daily as a preventative measure.
