We've been drenching ourselves with everything this new skincare line makes since previews of Nude came out last fall. Nude's probiotic and omega oil-enriched line is the real deal. When we heard Nude was produced in part by Ali Hewson, Bono's wife and creator of the eco-fabulous Edun clothing line - a woman who clearly has great taste - we had high hopes. And Nude has not let us down! This Cellular Renewal Serum is fast-absorbing, deeply effective and rich in N-probiotic active cell nutrient, stimulating the skin's own collagen and hyaluronic acid production for visibly rejuvenating results.
