Used on Back of Hands
Can't use on my face. Oily skin. If I use thick moisturizers on my face, my pores get congested. And I know it's oil-free but it's a liittttle too thick for me personally (might be perfect for someone else's face, especially if they have dry skin). I got the mini-size of this in a gift set (Mini Tatcha Treasures set). Don't want to waste it so I'll use it on the back of my hands (they're super dry). It's quite moisturizing. It's thicker than the Tatcha Water Cream. That's the only cream I can use on my face (just a little). I'll use this thicker one for my body.
