In choosing DIY ingredients, their absorption rates may be most important. It essentially means, how long after I apply the ingredients will I still feel them on my skin?
When I started DIY natural skincare, I tried using a macadamia nut oil moisturizer. After all, nut oils are available and are full of healthy fats. It was a cold January day, and my skin was so dry I thought it might crack. An hour later, I still felt an uncomfortable, greasy film on my face. I under-estimated just how slow a slow absorption rate can be.
