Q: What protective ingredients should I look for in a daily moisturizer?
You want sunscreen to be listed as one of its active ingredients. (The actives in a formula must adhere to FDA guidelines and be listed separately on the label.) Look for chemical protectors avobenzone, oxybenzone, and homosalate, or physical protectors zinc oxide or titanium dioxide.
