Safe alternative to benzoyl peroxide?

It's now a year since GlaxoSmithKline discontinued their mega popular acne treatment, Panoxyl Aquagel. (Read my infamous Liz Jones-style takedown here.) I thought my life was basically over because my acne would come back worse than ever before and there wasn't another benzoyl peroxide product on the market that I could use to keep the pesky bubonic boils at bay. Well, there is Quinoderm, but that's a disgrace. In the end, the acne did return pretty badly but for the most part it's been ok as long as I can use my foundtion and concealer to effectively cover it. There was a few months around October time when it was the worst it's ever, ever been, but that was due to a horrible bereavement I suffered. The spots were massive and horrendously painful but I suppose it was only a reflection of what I was feeling on the inside. Anyway, thankfully that seems to have calmed down now and my skin manageable. But of course I'm still quite spotty - sadly, I don't think it's ever going to go away now, it seems to be here to stay. 

It means I'm always on the lookout for a new acne product but there really aren't many available here in the UK. So I thought I'd give tea tree oil another shot. I always used to put it on my spots back in my teenage years but it never seemed to achieve much and stung like hell. This time I thought I'd use it just as I did the Panoxyl Aquagel, applying it to the whole affected area of skin as a preventative, not merely dabbing it on individual spots. It really works great like this and is keeping things under control. And all without those hideous harmful chemicals that do God knows what to the body! My skin is clearer in the morning and just feels healthier and smoother. Tea tree oil is only about £3 too, so even though it uses up quite quickly, it's nice and cheap to buy some more. I'm sold! Personally I use the pure oil with no problems but you may wish to use a diluted version. I put it on after my moisturiser which probably helps protect the skin from any burning sensation.
