Although the recipe calls for "fragrance oils" - don't use them! Fragrance oils are toxic synthetic oils, they're NOT skin friendly! Instead, use essential oils! They'll boost the health benefits of your scrub and they're just as yummy smelling as the fragrance oils are!
Also, use Almond Oil, not Canola. Canola oil is one of the top "GMO foods" out there. Now while this isn't being eaten, there is really no need to put more money in the GMO food producers hands. Plus, Almond Oil is EXCELLENT for your skin! It's been used for thousands of years for skin and hair care, and with good reason!
