I use a scrub that actually tells you how often to use it(most products don't). It says to use it every two or three days so that is what I have been doing. I use @mosphere tea tree oil facial cleanser for two days then I use the scrub. I love the scrub because it doesn't seem to matter how long or hard you scrub, it does not irritate my skin.
Sorry to say though I believe the @tmosphere line is only offered in Canada. They apparently make shampoo, soaps, teas, pure tea tree oil, facial cleaners and moisturizers.
