BETTER PROTECTION 72 @dayspamagazine • June 2019 So, the proposed FDA rule sought feedback to create more consistent testing protocols and record-keeping requirements to help the agency assess industry compliance with regulations. VISIBLE LIGHT PROTECTION In recent years, sunscreen formulations have evolved to offer new protections against visible light and infrared radiation (IR). "Studies suggest that blue light—visible light from computer screens—and IR can cause skin damage," says MacPhee. He notes that IR in particular upregulates the production of MMP1s, enzymes that can degrade the extracellular matrix. "The skin reacts to exposure as if it's being damaged, which increases the presence of free radicals," he says. Ingredients touted as defending skin from blue light and IR are typically antioxidants, such as CoQ10 and vitamin E. "To block IR you need to wear something opaque, such as clothing or a hat," says MacPhee. "But adding antioxidants to sunscreen can help offset the production of free radicals. We can also use enzymes that specifi cally downregulate MMP1s, as well as peptides to help skin healing." © GETTY IMAGES
