What it is: A reimagined retinol that delivers all the benefits of retinol without the irritation.What it does: Don't let the word oil fool you; this ultralight formula nourishes like an oil but absorbs fast and without a trace. Retinol's game-changing benefits are boosted by NIA-114, neutralizing irritation and improving the look of fine lines, wrinkles, rough texture, dullness, dehydration and loss of firmness. How to use: Apply 1 to 3 drops to clean face each night, before or mixed with moisturizer. Upon application, the oil transforms from orange to colorless, so it won't transfer to skin or stain your pillow.Pro tip: Layer S.T.A.R. Light Retinol Night Oil underneath a nonretinol moisturizer and/or over a nonretinol serum. Pair with the brand's award-winning Advanced Retinol Eye Cream for an overnight success. 1 oz.
