In recent Beauty Lab tests, this drugstore retinol formula scored highest for reducing the appearance of wrinkles, brightening skin, and hydrating. 100% of consumer testers agreed that it made skin feel more moisturized, and Lab tests confirmed, seeing a 20% increase in skin's moisturization after just six hours and a 27% increase in firmness over four weeks. "It seemed to work as well as my prescription retinoid," said one tester. "When I woke up each morning, my skin was firmer and smoother," raves another, adding, "I can see that fine lines are less noticeable."
