You can pick whatever oil you want, depending on what properties you need. If you need a hydrating oil, try olive oil or jojoba.  Olive oil is very moisturizing and has anti-inflammatory properties. It contains oleocanthal, which can help reduce irritation. (source) Avocado oil is a great moisturizer because it is rich in fatty acids (i.e. Oleic acid) and vitamin E. (source) Apricot oil (I use this one) is great for soothing dry skin.  Jojoba oil is moisturizing. It can soothe dry skin, reduce redness and inflammation, and help repair skin. Coconut oil – is moisturizing while being naturally antibacterial and has antifungal properties, perfect for feet. Fractionated coconut oil is liquid at room temperature, which will leave a more consistent and fluid sugar scrub. Almond oil: Is great for skin since it contains fatty acids, vitamins, and minerals. It helps moisturize, soothe, and may improve some skin issues. (source)
