What can I do to safely add more antioxidants?

I like my pm routine with alternating slugging with CeraVe Healing Ointment 1-2x a week and switching between BHA and retinoid every other night when I’m not slugging for hydrating. I want to add more of an antioxidant approach in the morning to fight free radicals and I’m not sure if my Ascorbyl Glucoside is doing the trick.
