The tea on celebrities’ skincare routines? From “Real Housewives” to Disney stars, plenty of famous folks rely on TruSkin.

And on Wednesday, the label expanded its lineup with a new green tea-powered product: the Caffeine Facial Serum ($16), a formula packed with energizing ingredients like matcha.

In addition to 5% caffeine, the just-dropped product contains niacinamide (to target skin texture), hyaluronic acid (for hydration) and ginseng (to help energize and balance the complexion).

While it’s brand-new, the serum’s already garnering great reviews on Amazon.

“I found this serum to be a medium weight, smooth but not quite silky formulation that applies easily and sinks in readily,” one satisfied shopper wrote of their first impressions, while another dubbed it a “good serum for a decent price.”

If history is any indication, the new serum just might pop up in stars’ routines soon, too.

Kyle Richards once shouted out the brand’s Vitamin C Facial Serum ($30 $20) in an Amazon livestream, calling the popular skincare ingredient a “miracle” and saying she can “see a difference” after using it, per Prevention.

Alexandra Daddario’s also a TruSkin devotee, as she applied the same serum in a Vogue “Beauty Secrets” routine breakdown.

And “Descendants” star Kylie Cantrall is such a fan, she even partnered with the brand on her own bundle of products, in addition to singing its praises on social media.
