As someone with a fairly simple skincare routine, it can be hard to convince me to trust any new products. However, vitamin C is a staple in my makeup bag and has helped keep my skin looking bright, clear and youthful. The market is jam-packed with antioxidants claiming to help with cell regeneration and hyperpigmentation, but Amazon shoppers feel they've found an incredible option. It's Eva Naturals Vitamin C Serum — great not just for summer but all year long — and it's down to $15 right now.

With over 35,800 Amazon reviewers singing this magical serum's praises, it's a clear winner. "This serum REALLY works!" one shopper declared."I was amazed by the fast results, and I feel way more confident with my face and skin. I even cut back on makeup because I don’t have blemishes and dark scars to cover anymore."

The Eva Naturals Vitamin C Serum is made primarily of vitamins C, E and B3, along with retinol, salicylic and hyaluronic acids. These ingredients are known to aid in preserving skin's suppleness and preventing visible signs of aging, clearing up breakouts and acne scars and improving overall skin tone and texture.

Amazon shoppers are hooked on the Eva Naturals Vitamin C Serum and its many benefits. Here's what they had to say. "I've been looking for a product that is for anti-aging and treating acne that does not burn my sensitive skin. This serum did not burn at all, and the redness was calmed down by the next morning!" one reviewer raved.

It gives a glowing complexion, as another serum user confirmed: "This stuff is so amazing; after just a couple of weeks of use I saw such a difference (and I'm 60 years old!). Honestly, I keep touching my face — it's so smooth and soft and moisturized. But don't take my word for it: My boyfriend (hey, 60 is the new 40!) regularly tells me how much he 'loves' my skin, that my skin is so great! Booyah!"

"I have been using vitamin C serums for almost two years now, and I find that this is my favorite," an Amazon shopper wrote. "I have no more purple marks along my jaw, and I have noticed that other forms of hyperpigmentation (like melasma) are slowly going away."

"I'm in my late 30s and had horrible cystic acne all along my jawline for several years. I tried so many products and supplements, and nothing worked. This product has cleared my face completely of cystic acne. I've been using it for about a year now, and I have three extra bottles on hand in case they ever stop making this! Also, fine lines are hardly noticeable," a final reviewer explained.
