"i have taken yaz, gianvi, and loryna (gianvi and loryna are the generics for yaz) and i&#039;ve had excellent results with my skin. i never get pimples anymore and my skin has never been so clear. it did take 2-3 months for my skin to completely clear up though so you have to be a little patient. i also have never experienced any other side effects with this medication, so i guess i just found the perfect birth control pill for me :)"
