"I'm really into the Topicals Like Butter Mask, which I use on days where my skin is feeling really dry, dehydrated, and itchy. It really came in handy this winter when my heater was constantly cranked all the way up. I have eczema, so anything that helps soothe and calm my ultra-sensitive, reactive, dry skin is wonderful. And this mask does that. It's also nice that you can wear this as an overnight mask on days where you just want a simple, quick evening routine or wash off the mask if you just want a little kick of moisture."
