    Love the new OS-01 Face Rich Cream

    I love the new Face Rich Cream, my skin is so soft and stays moisturized all day, I have been using it for a couple of weeks and no breakouts. This is my forth OS-O1 product, and I love of them. I have very sensitive skin, and none of these products has ever broken me out in the one year I have tried them.

    Love, Love, Love!

    This is the face cream I have been looking for for YEARS. Truly, years! I had been using the regular OS-01 Face for a while but paired it with a barrier cream on top for extra moisture since I live in a very dry climate. The rich cream is the perfect balance of light and moisturizing! I only use the barrier cream now if my skin is sunburnt or wind chapped. I get so many compliments on my skin and I don't regret using this cream (but maybe my wallet does). My skin feels bouncy, soft, and glowy and I really do believe this has been a big part of the journey!
