"Lo Loestrin = Acne cysts! I have always had clear skin [with the occasional break out, but nothing serious] and since switching to this pill about 12 months ago, I've had a never ending cycle of painful and ugly red blemishes. My dermatologist assessed my skin and after two minutes with me determined that I had Lo Loestrin skin. She said it is absolutely the worst for skin because of its significantly lower estrogen levels. Anyway, I just wanted to share this knowledge. I'm switching back to Yasmin."
