“Coffee does not have any effect in terms of causing cellulite or dimpling of the skin,” says board-certified New York dermatologist Dr. Bruce Katz. “Coffee also doesn’t have any direct effect on acne, but it could potentially make the acne you do have worse by increasing the amount of stress hormones like cortisol. Anytime your body is under stress, the increased cortisol leads to an increased amount of oil produced, which can make acne worse.”
