Crystal Retinal™

How It Works: Clinical-grade vitamin A, otherwise known as retinoic acid, is an exceptionally powerful skincare ingredient for youthful-looking skin. Highly potent and wildly efficacious, it is able to trigger cellular regeneration and collagen production to fight all visible signs of ageing. Retinoic acid is only available with a prescription, but vitamin A is available over the counter in the form of retinol skincare products.
