    Great hydration

    Love it! I have combination skin, and despite my skin being oily, it was always also dehydrated and my skin would sometimes peel because of it especially on my forehead. Just after a week or two of using this I could start seeing a difference, my skin stopped peeling and I feel like my skin has gotten more glowy and plumper! Highly recommend. (The results in the photos are due to a combination of inkey products though.)
