Emma Stone revealed her stuggle with hormonal acne and stress related acne. 

The Revlon cover girl said "I'm actually pretty interested in skin care, because I had bad hormonal acne, they put me on Accutane for it," to Refinery 29. After two months of Accutane, she went off it due to dry skin, mouth lips and eyes. "I realize how debilitating and embarrassing it can be to have cystic acne," said Stone.

To keep her skin clear and beautiful Emma has a structured routine "I use Cetaphil, the bar soap, and then these pads that I get from the dermatologist and then Elta lotion." To ward off acne her tip is using "tea tree oil," she doe not put too much on due her sensitive skin.

"Whenever it's been really bad, I've gone to the dermatologist to get those cortisone shots," said Stone, admitting she is terrified of needles but to keep her skin clear she goes by the Montra "No Pain, No Gain."
