Other staples in Brad’s strict regimen are brown rice and beets since they are high in phytoceramides, which many people take as supplements to keep skin hydrated and plump.

“What you put in your mouth shows on your skin,” says Beverly Hills dermatologist Dr. Ava Shamban, who does not treat the father-of-six. “His diet will help Brad’s skin repair itself.”
