I started using this when I came back to Canada after spending a year in a hot 'n' humid climate. So, my face when it felt winter again was, like, WHY ARE YOU DOING THIS TO ME? Every time I put moisturizer on it just sat on top of my wildly dry skin, no matter what I tried. And my nose? Flake city. Not cute. After hearing rave reviews about The Ordinary, I went into Deciem and spoke to one of their beauty specialists, who basically threw this bottle at me. They put a drop of hyaluronic acid on my left hand and added moisturizer, then added only moisturizer to my right hand for comparison. One minute later, my left hand had absorbed all of the moisture, and my right had a white cast of cream left on it. I was sold, and now I can't live without it.
Get it from Sephora Canada for $6.80. It's also available in a value size, which is great if you plan to use it all over your bod.
