Amazon's Bestselling Skincare Product Has 7,000 5-Star Reviews (It's On Sale)

Updated 07/13/18

Amazon's review section has unveiled yet another cult-favorite skincare product—and this one's already on sale for Prime Day. According to the sheer number of sales and positive reviews, TruSkin Naturals' Vitamin C Serum is Amazon's number one best-selling skincare product, and the 9627 customer reviews explain why.

Packed with vitamin C, vitamin E, and hyaluronic acid, the serum was formulated to target the most common signs of aging, including fine lines, wrinkles, dark spots, hyperpigmentation, and dullness. Enthusiastic reviewers of the product have graciously shared before-and-after photos of their skin, many of which depict faded sun spots and acne scars, fewer breakouts, assuaged redness, brighter skin, fewer fine lines and wrinkles, and overall smoother skin tone.

"If you care about your skin, you should not hesitate in purchasing this serum," reads the top-rated review from Allie Carter, who specifies that she was not given a discount or freebie by the company in exchange for a positive rating. "My skin is still not perfect… but overall, it has helped tremendously. I am just an honest girl hoping to spread the word on what has brightened me up."

While the hyaluronic acid helps to moisturize the skin, this product's hero ingredient is undoubtedly the vitamin C. This potent antioxidant helps fight the free radicals that attack our skin cells and cause signs of aging. "If you're not using [a vitamin C serum], it's definitely time to step up your anti-aging game and give your skin some serious protection," said celebrity esthetician and skincare expert Renée Rouleau to our sister site Byrdie. "Applying a vitamin C serum topically to the skin can essentially...make your skin look brighter, fresher, with a youthful glow."

Best of all, the TruSkin Naturals serum is currently on sale for $20 as a part of Amazon's early Prime Day discounts. Shop the hero product below.
