So, how can that lead to breakouts?

Acne is an outward manifestation of inflammation," explains Dr. Gersh.

There’s also a rash that can rarely appear with exposure to progesterone calledautoimmune progesterone dermatitis."

“Not everyone on an IUD will experience breakouts,” adds Dr. Garshick.

Another common prescription acne medication isclindamycin, a topical or oral antibiotic.

There’s alsoAccutane (isotretinoin), adds Dr. Garshick.

(These arethe best drugstore acne products, according to dermatologists.)

Bottom line: Acne isn’t the end of the worldand, again, IUDs won’talwayslead to acne.
