According to this study a massage oil containing 3% Grapefruit Oil helped to reduce abdominal fat so I decided to adjust the formula of my existing body butter to include 3% Grapefruit Oil. I sent my recipe off to a cosmetic chemist a few weeks ago and I received my Cosmetic Product Safety Report today. I plan to use the Abdominal Balm once a day to help my body to mobilise the fat from my stomach. I already do moderate amounts of cardio so I'm going to keep that up to stay in good health.
