I get some now and then along my jaw line which is hormonal and on my back (not sure where that's coming from but it's usually around that time of the month).
I don't take the pill because I am allergic to the hormone and I visit my naturopath and my mum is a homeopath.
I watch what I eat to a degree, I do splurge a little hehe
I use Papulex which is fantastic, it's formulated for acne. I get the gel wash and oil free cream that doesn't clog your pores. It's worth investing in.
I also use Anti Blemish Concealer by Clinique, it's so good that I can leave it on over night if I forget and my skin is actually smoother in the morning!

They are fairly new to AUS but worth a go! And their skin care stuff is nicer than using proactive that strips your face.
Hope this helps!
