"I'll admit, I was a bit of a facial roller sceptic — I didn't understand how a stone could possibly improve the look of my skin. That all changed when I finally tried the Herbivore Rose Quartz Facial Roller ($40). I have some pretty intense seasonal allergies, and during the changes in weather, they get particularly bad and make my face extremely puffy. Rolling this cold, rose quartz stone across my face a few times each morning helps take down the swelling — and it helps that the massage just feels really good." — SS
