Homemade Grapefruit Bodyscrub is one of my favorite things. My recipe is loosely based on Lush Ocean Salt Scrub. My version is all natural, vegan friendly and safe to eat. (Although it tastes pretty bad lol) It smells amazing and works great on sensitive skin.
I like to use a mix of fine and coarse ground sea salt in my body scrubs. Finer salt is more gentle for people with sensitive skin. Coarser salt is able to exfoliate more and help your skin get clean. Most grocery stores carry both. If you want to be fancy you can get himalayan pink salt or celtic sea salt which have minerals that may or may not provide added health benefits.
Next I add oil. Different oils have different benefits and treat different skin issues. For example, grape seed oil strengthens and tightens skin while moisturizing to fight aging. Grape seed oil has anti-inflammatory properties that make it good for people with sensitive skin. Coconut oil has a nice smell and contains vitamin E to help repair damaged skin.
