Can I use tretinoin cream, a gentle cleanser, and glycolic acid toner in the pm? And then a benzoyl peroxide cleanser in the am?

Hello, this seems like a lot of active ingredients to be using at one time. It's also very important that you only use tretinoin at night since it makes you more sensitive to the sun. Start slowly introducing one active ingredient into your routine at a time to prevent over irritating the skin. Good luck!
