Somewhere else in New York, makeup artist Kelsey Deenihan was prepping Emma Chamberlain‘s skin using the same little wand after using a few CeraVe products. “Amazing to use after your skincare to help the products further penetrate the skin so you stay hydrated longer,” Deenihan wrote in an Instagram Story. 

In a grid post, Deenihan also referred to the SolaWave wand as “the best beauty prep tool” — and she’s not the only one who thinks so. Reese Witherspoon, Nicole Kidman, and Mandy Moore are just a few other famous faces that makeup artists have used the pocket-size red light therapy gadget on for red carpet appearances.  

It packs four powerful skincare technologies into one tiny tool: Microcurrents stimulate facial muscles to improve signs of aging, red light deeply rejuvenates vibrancy and appearance of skin, low vibrations boost circulation and provide a depuffing facial massage, and therapeutic warmth reduces redness and amplifies the absorption of products. 

According to the brand’s website, you’ll see your best skin in two weeks when you use the wand for five minutes, three times a week. Just use it with your favorite serum, like Sims does, or try its activating Renew Complex Serum. Aside from its celebrity fandom, the SolaWave reviews speak volumes as to why it’s a must-have in your beauty routine. People say their skin is firmer and has an overall more even tone since using.  

TL;DR: If you don’t already own a SolaWave wand, you need one — especially while you can get it on sale. The company is offering 25 percent off plus free three-day shipping in honor of Mother’s Day. Just enter the promo code MOM25 at checkout. You can also snag the wand on sale on Amazon, too.
