Jojoba oil is the one skincare product that I think nearly everyone could benefit from. Yes, really, everyone. Don't let the word oil scare you. If you have dry skin, jojoba oil is your best friend. It moisturizes like nothing else. If you have oily or acne prone skin, jojoba will help cut back on the oil that your skin produces, restoring balance. Unless you go nuts with it, it won't make you shiny or greasy.
I use it on my face either directly or mixed with moisturizer, mixed into my hair conditioner, to remove makeup, added to my body lotion, etc. I even have a spray bottle with a water/jojoba oil mix that I shake vigorously and spray onto my hair and face for a pick me up. There's a more in-depth overview of jojoba oil here. It's definitely worth a try if your skin is stressed out!
An 8 oz. bottle of organic jojoba oil is $14.75 from acne.org
