Hi. Sorry to hear that your acne developed after switching pills. The pill does mess with the metabolism and can cause all sorts of weird problems (mine made me slightly hypothyroid - crazy, isn't it?). If you have acne to start with (like I did) the pill tends to make it slightly better rather than the other way around. If your experiencing problems with the pill you're taking and can't change it back to the one you had before, have you tried asking your doctor for acne medication? There's one called Minocin (in the UK - not sure where you are, sorry!) and that's extremely effective. Topical lotions for acne tend to make the skin very sore and I wouldn't personally recommend them, especially if you have sensitive skin.
Spots tend to heal up a little better if you don't wear any make-up at all. I remember walking around during sixth-form at school and feeling awful because my face was covered in acne. It was so tempting to cover them over. Now what I do is wait until the last possible moment before I go out to put on any make-up and as soon as I get home, I wash it off. I also don't wear it at weekends (if I'm at home). It lets your skin breathe.
I hope you manage to rid yourself of the acne soon. Best wishes, kiya
