"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&#039;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&#039;m switching back to yasmin."
