Vitamin C is having quite the moment on TikTok this summer. But trust us when we say that it’s not all just hype and spon con. Vitamin C (aka ascorbic acid) is a powerhouse antioxidant that works to brighten skin, fade dark spots, and prevent fine lines and wrinkles. Unfortunately, vitamin C as a topical active ingredient can be pretty difficult to stabilize, making skincare products formulated with it a tad pricier. However, thanks to Amazon’s iconic Prime Day (happening now through July 12), we’ve found MAJOR savings on a serum that over 16,000 shoppers rave over.

The reviews speak for themselves, with shoppers writing that they “can’t even believe the difference it does from just one application” and other’s saying their skin is “noticeably softer [and] smoother” after long-term use.

“I have combination skin and hyperpigmentation from acne, and already I am seeing a difference in my dark spots,” one shopper writes, “My skin is brighter, more even-toned, and glowing. Even the texture of my skin has improved.”
