Using facial ice globes is always a good idea — and not just when there’s a heat wave. The cooling effect of these fun skincare tools doesn’t just feel refreshing, they also tighten and lift skin for a more sculpted appearance. Sarah Jessica Parker has known this for a long time (like, as long as she’s been in show business), which is why she always carries the Sundree Cooling Facial Globe in her bag during filming days.

Parker revealed on Instagram that she began toting this ice globe around when And Just Like That first began production four years ago. Most days were spent in the balmy New York City summer heat, so she used the pretty purple tool to cool down in between takes. When she was able to go back to her trailer, the actress managed to indulge in a little more rest and relaxation, gliding the globe along the contours of her face to promote circulation, stimulate lymphatic drainage and calm inflammation and puffiness caused by long hours on set.

I’ve long been a fan of cooling ice globes myself, and I use one in my daily skincare routine. Swiping the chilled tool along my face every morning energizes my mind — and complexion — to help me start my day on the best note. While you can easily run this across your skin without any serums or creams, I find that I get the best glide when I pair this with a hydrating serum. It’s like a mini facial from the comfort of my couch.
