so that in itself is a good trick. I hope to be able to continue ... [SEP] I used this product when I lived in California's Central Valley because it kept my skin consistent in the varied temps of living in a desert climate. It became harder to find the Lumene line in general without the SPF additive so I switched to another line when I moved to Southern California by the beach. Last year I moved to Phoenix, a desert area again with wildly varying temperatures, and I noticed my facial skin this winter was getting red and blistery. The corners of my eyes were even beginning to droop as my skin was becoming tight. I bought this on Nov 26, used it for two days, and my skin is dewey and back to normal. And I am a 51 year old man, so that in itself is a good trick. I hope to be able to continue to find this line without the SPF because I will become a devotee once again.
