"got this june 2014 got it out march 2015. within 3 months of having it, i developed horrible acne around the jaw line and forehead with cysts on my lower jaw. previous to implanon, i was on zovia for 2 years. with zovia i had weight gain, breast tenderness, but very clear skin. with implanon, i lost 40 pounds, which i attribute more to diet and exercise, developed acne, but had no breast tenderness, periods or mood swings. to me the terrible acne isn&#039;t worth it so i got back on zovia. also, my friend got implanon about a month ago and already had horrible cysts on her chin."
