If you're someone who wants to get into the retinol game but needs something gentle, this one by Obagi360 is perfect for those with sensitive skin. You get all the benefits of retinol — including a reduced appearance of fine lines and dark spots — without the irritation. It's best to use this at night. You can try using it once or twice a week, and work up to using it every other day.
