is not intended to be used as an acne
treatment, and is not approved for that use.
It can, as a side effect, make acne better, or worse. I've had patients tell me that their acne improved while using the Nuvaring, and others have said that their acne was worse than ever while using it. So it's totally unpredictable. Rather than roll the dice, see a dermatologist for a proper acne regimen.
