This is the perfect wish serum. Just like wishing for world peace when you blow out your birthday candles, the concept of radiance is kind and broad. Does it do anything? Does it mean anything? Who knows, but it costs over one hundred dollars and you can rub it on your face. This serum needs to be applied directly before or directly after a toner, and we can’t remember which order, but if you get it wrong you may as well throw gutter water on your face and call it a day. Dream on, girlie!
