Boil 1.5 liters (0.4USgal) of water until it is very hot. Pour the boiling water into a bowl as soon as you can, whilst it is still very hot. Move your face above the bowl of hot water and face it downwards (put a towel over your head for maximum benefit). Youll be able to feel a lot of heat getting to your face as if it is getting steamed. This is a very good method to reduce acne and any scars you have as the heat fights it back into your skin and almost kills it.
