I live in the desert and I used this product all summer long. Thought about going back to foundation for the winter months, but decided to order another tube instead. It doesn't have a high SPF rating, but I apply a little powder over it and it seems to do the trick. It really does just even out the skin tone and has a more natural look. Never have that drying feeling around the eyes that some foundations can leave you with by the end of the day. The fact that it seems to adjust to you're very own skin color (fair and blonde in my case) is very clever. Plus, you get a lot of applications per tube. Good stuff!
