It's no secret that the key to looking younger is to appear well-rested. We sit down with one of the best and brightest oculo-facial and reconstructive surgeons in the country to talk about what you need to know before getting filler under the eyes. Dr. Maryam Nazemzadeh of Sanctuary Cosmetic Center, talks about which common filler areas can cause blindness (it's not the tear trough but it is somewhere you wouldn't expect), and takes us through exactly what happens in this non-surgical procedure. This is a must-listen for anyone who wants to tackle dark circles and under-eye bags.
