This is one of the most common questions we get from GLO users wondering whether they are applying too much, or too little, whitening gel. The answer is that a little goes a long way and you really only need to apply a thin layer of GLO whitening gel to your teeth for effective whitening. The key is to make sure the gel is covering all the surfaces you want to whiten, including the spaces between your teeth where stain likes to hide.
