This Anti-Aging Vitamin C Serum Sells Every 4 Minutes on Amazon

“I am almost 70 years old and have tried many products—I haven’t noticed a difference until I used this serum.”

In case you missed it, incorporating a vitamin C serum in your skincare routine is a must-have for glowing skin. The superstar ingredient has gained some major popularity over the last two years thanks to its ability to work wonders on all types of skin concerns, from hyperpigmentation to dullness to wrinkles. While Amazon is home to many popular vitamin C serums with thousands of reviews, shoppers seem to be consistently drawn to the InstaNatural Vitamin C serum—so much so, that a single bottle of the product sells every four minutes.

This vitamin C serum has racked up over 3,500 five-star reviews from customers who are blown away by its results. Alongside vitamin C, the serum is also made with ferulic acid, hyaluronic acid, and sea buckthorn oil. These additional ingredients help enhance the serum’s benefits by fighting against environmental stressors, providing moisture, and reducing inflammation.

A topical daily vitamin C serum is one of the best inventions the skincare community has made in regard to slowing down visible skin aging, such as fine lines, wrinkles, and brown spots,” celebrity esthetician Renee Rouleau previously told Real Simple. “This is especially true when it’s applied on a daily basis.”

To buy: $18; amazon.com.

InstaNatural says its serum will help tighten, tone, and smooth your skin’s texture, plus target everything from clogged pores and acne to fine lines and age spots. Some customers go as far as saying the serum is like a “nectar of the gods for your skin,” and has achieved seemingly impossible feats like healing 10-year-old acne scars.

“I don't normally write reviews but I absolutely LOVED this serum, so much so that I felt obligated to publicly endorse it. Since I started using this serum every day I have noticed a significant difference in the texture and overall tone of my skin. I spend a lot of time in the sun and dark spots are my nemesis. This serum brightens my skin and has helped significantly reduce those nasty dark spots,” one shopper wrote. “Additionally, the array of ingredients in this serum work to hydrate my skin and I have been getting closer to that glowy complexion I’ve been striving for. Lastly, can we talk about the price? When I first decided to amp up my skincare routine I researched different serums for WEEKS and was hard pressed to find one for a reasonable price. This is more than worth the money and in my opinion works just as well as some of the pricier brands I have tried. It smells good too.”

Not to mention, all of its ingredients are natural and preservative-free, and a bottle costs just under $20—a total steal.
