Evening primrose oil is fantastic. I use it for rosacea and my skin has improved a lot. I have less redness and my skin is softer and more hydrated.
I only use all natural evening primrose oil. I take just a few drops and apply it all over my face in place of my moisturizer before I go to bed. My friend uses this oil as well but she doesn't like to leave it in. So she uses the oil to cleanse her face (massages it in for five to ten minutes) and then washes it off. She likes it too.
