Every age benefits from retinol. Retinol in your early 20’s is important for preventative reasons to keep your skin at its best performance. In your 30’s your skin will continue to behave as it was in your 20’s. In your 40’s and 50’s retinol will continue to work on cell turnover and tackle wrinkles, even deep ones. The skin in any age will always benefit from retinol – so never stop using it!
