You know scrub is very easy to make at home and certainly it is more natural. Here's one recipe.
Take coffee specks that you've boiled and already drunk. Take a little gel for washing your face, add some specks and massage your face and neck with this mass slightly for 3 minutes, then wash away and apply moisturizing cream. Use the scrub once a week and for the whole body as well.
You'll see, your skin will be smoother than ever!!!
