Eye serums and creams monopolize the beauty marketplace, so it's not hard to find one. But finding one that works is a different story. I've been seeing aesthetician Kimmy Williams of Acqua E Sapone in San Francisco for a few months now and she singlehandedly changed my face with her innovative products from her own line that are effective, no-nonsense and affordable. So, I was curious to get her take on what makes a smart eye product. Williams shared the four key ingredients that she includes in her Glyco-Peptide Eye Serum and why she recommends you choose an eye product with these four qualities.
