Moisturizing is important for everyone, even if you have combination or oily skin, something I personally didn’t learn until later on in life. Jeffrey Paul, a celebrity makeup and hair professional, told Total Beauty in the aforementioned article that essential oils can play many roles in your moisturizing, beauty, and grooming routines. And while it’s necessary to dilute many of them before applying to the skin, using what would normally be a carrier oil — like apricot, avocado, or almond — straight instead of mixed with essential oils can also be a good way to boost your skin’s moisture content. Just make sure that you’re buying high-quality oils.
