Having such a cool name and coming from Hawaii how could this oil be not good? Well, it is good - it's excellently absorbed by the skin and is used traditionally by the Hawaiians to soothe sunburn and other inflammations.
Research confirms this: it's shown to have anti-inflammatory, pain reducing and wound healing properties. It's also a particularly rich source of moisturizing essential fatty acids linoleic and linolenic (about 42 and 32%) (and it's not so rich in oleic acid - around 15% - that can be good even for acne prone skin).
