There are many primers on the market, but not all of them actually perform to the claims on the bottle. Rouge Bunny Rouge Serene Light Skin Perfector ($57) is one that lives up to the hype. The British brand incorporates Diamond Core Powder into its Skin Perfector to transform invisible UV light into blue and green light, evening-out sun damage, discoloration, wrinkles, and any imperfections. It’s pricey, but worth it. Patricia Margro, owner of Maison Rouge (which stocks the product) in Bronxville, is a major fan. “This primer sets the tone for perfect skin, giving a glow for any skin type without too much shimmer. It creates flawless skin, with or without makeup,” Margro says.
