Save on the serum Kyle Richards called an ‘automatic refresh’ at this pre-Prime Day sale

While celebrities have access to every beauty product from A to Z, many are loyal to superhero skincare ingredient vitamin C.

And TruSkin’s bestselling Vitamin C Facial Serum ($49 $35) is a longtime Hollywood favorite, with famous fans ranging from Kyle Richards to Khloé Kardashian.

What’s more, you won’t need a Beverly Hills-sized budget to score some yourself; while Prime Day is still weeks away, the company’s currently slashing prices by over 25%.

Kyle Richards once raved about TruSkin in an Amazon livestream, calling the serum “a miracle.”

“When you put this on your face, always the next day … you can automatically see a difference,” she added. “It’s an automatic refresh.”

Khloé Kardashian also reportedly included the product in an Instagram Story snap, while Alexandra Daddario shouted it out in a Vogue “Beauty Secrets” video, raving, “topical vitamin C is great.”

And “Descendents” star Kylie Cantrall is such a fan, she even partnered with the brand on an exclusive bundle featuring the brightening formula.
