A simple mixture of coconut oil or olive oil blended with essential oils is what I use whenever my skin becomes dry and irritated.
In a small jar (like empty baby food), fill with either olive oil or coconut oil and add 10-20 drops of essential oils. Mix together, then apply to your skin like a body cream. You should only have to use it sparingly as the coconut/olive oils are quite concentrated and better for your skin than pretty much anything you can buy at the pharmacy.
* Coconut oil is solid at room temperature, so you may need to gently heat it up in a warm water bath before you mix it with the essential oil*
**Keep the oils away from clothing as they can stain**
Some of the best essentials oils for this condition are:
Sandalwood (very expensive, but beautiful)
If you continually get dry skin, also please check to make sure you are hydrated and drinking enough water. Stay healthy!
