Overall Opinion: Roc Retinol Correxion Deep Wrinkle Night Cream proves that you don't necessarily need to spend tons of money to get really good results from a wrinkle cream. Although there are better retinol creams out there, you really can't find one as good as this for the price.

RoC Eye Cream with Retinol is clinically proven to address 3 major eye area concerns: lines, dark circles, and puffiness.

This advanced age-defying cream is clinically proven to visibly reduce wrinkles by up to 50%, even deep wrinkles, in 12 weeks. 93% had a visible improvement in deep wrinkles in 8 weeks.

Retinol also stimulates collagen production, which is another way it diminishes dark spots. Not only will dark spots be reduced, but wrinkles and sagging skin will also begin to diminish, and the effects of retinol products will continue to work just as effectively over time.

RoC's retinol is especially good, because it contains stabilized retinol in a single-use capsule. It can also benefit those who have depressed or rolling scars, and it must be used regularly (several weeks to months) to really work.
