Beverly Hills dermatologist Dr. Zein Obagi will be at Nordstrom NorthPark this Saturday from 10 am-5 pm promoting his new skincare line, ZO Skin Health. So what’s different about ZO, you ask? Well, Dr. Obagi doesn’t believe in moisturizers, because he thinks your skin becomes addicted to them, which causes them to “become lazy and slow down.” (Bad little skin cells.) Instead, his 11-product system uses the highest over-the-counter concentration of retinol–10 to 25 times higher–which attaches the body converts to retinoic acid, thereby stimulating collagen production. Or something like that. For a better explanation of this out-of-the-box thinking, you can visit with Obagi yourself and get your personal consultation. All you need to do is RSVP to 214-231-3900 x. 1417 by TODAY. The cost is $50, which can go toward purchase. Those who show up will receive a travel-size Oclipse Sunscreen + Primer SPF 30 while supplies last.
