Grapefruit essential oil can lift the spirits and combat fatigue. Topically, it is great for oily skin types and acts as a light astringent. Diffuse or apply topically in 2-5% dilution. Can also be added to a facial scrub.
The differences between the White and Pink Grapefruits are minor. The difference in cost is simply an example of supply and demand; there is more pink grapefruit produced because it is slightly sweeter than the white variety.
