We all know the importance of using SPF to protect your skin from UV rays, which helps prevent skin cancer and premature aging. But did you ever think that the sun could harm your nails? We just learned from nail professionals that UVA/UVB rays can turn nails yellow. Thank heaven for Zoya’s new Armor Topcoat/UV Block, a titanium dioxide-infused top coat that acts as a sunscreen for your nails. Not only does it keep nails from yellowing, it prevents your polish from oxidizing in the sun and turning funky colors. A beach bag essential!
