Choosing the right birth control to clear acne

Patient: Is Emoquette ((deosgestrel and ethinyl estradiol) and Ocella (drospirenone and ethinyl estradiol ) both safe options for my daughters, ages 18 and 20 to prevent and alleviate acne? Are there any serious health risks, and is there a better choice with good results for clear skin and less risks? Thank you, Leila taylor

Symptoms: Pimples and acne (my two daughters)
