I moved to Arizona 6 yrs ago and due to dry, low humidity, I saw after a year my face looked very dry, rough looking. I do not smoke or drink anything but water. But still it looked bad so I went to the health food store and bought Emu Oil and Evening Primrose Oil. I started to use Emu Oil, then tried Evening Primrose Oil. They both work excellently on my face. I use one or the other whatever is in stock at the store. My husband said he could see a big difference right away. My skin looks younger and has a beautiful glow. I'm 44 yrs old and people think I'm in my late 20's. That's something to smile about.
