"Is this a joke?" wrote a five-star shopper. "I used this once — ONCE — before bed...washed my face, applied this serum and finally my normal moisturizer and retinol. I woke up absolutely glowing, to the point that people were complimenting me ... My skin is so soft and radiant, I’m terrified that people will catch on to this and it’ll run out of stock. How is it possible that a serum could do this? Mind blown."
