I have sensitive skin that is also prone to breaking out a lot, I've tried so many things to help with my acne but none of them seemed to work that well except tea tree oil! I apply a drop of this on a clean finger and dab it on any blemishes I have. Within a few hours I notice a huge difference. The blemish is usually reduced to just a small red mark! I try not to use too much of this because it does dry out your skin and the smell is very strong so I recommend having a window open when using this. At £2.99 from Superdrug you can't really go wrong!
