"Sunscreen isn't the only way I can prevent skin damage," Kennedy says, and she's right. Day Preventive Treatment is formulated with vitamin C and other antioxidants to help defend skin against UV rays, pollution and blue light, applied before moisturizer and sunscreen for a full layer of daily protection. It also carries The National Eczema Association seal of acceptance. It's dermatologist-created, lightweight and easy to build into a routine you already have. We're gifting a FREE travel size with every $100 purchase.
