A serum is arguably one of the most popular skin care products folks seek out. They come in tons of different formulations and can positively change the skin's appearance for good if used correctly. One of the most common and widely available types contains the ingredient vitamin C.

Growing up, we've all heard that vitamin C is one of the most powerful ingredients we can incorporate into our diets. With its beneficial properties as an antioxidant and its aid in maintaining a healthy immune system, vitamin C's benefits show up in not only diet but throughout skin care as well. These positive effects usually go hand-in-hand with vitamin C-rich foods and drinks — but what about in our skin care?

While there are many vitamin C-centric products on the skin care market, some of the most popular retailing for $89 and up. Over 70,000 Amazon shoppers can't stop talking about the affordable TruSkin Topical Vitamin C Serum. Thousands are saying it's the most effective they've ever used.

According to, topical vitamin C brightens the look of dull skin by helping it "neutralize free radicals and reduce environmentally-induced signs of skin aging." Vitamin C can also reduce the appearance of an uneven skin tone, fade dark spots and ultimately reveal bright, more radiant skin.

This serum also boasts an "advanced formula designed to target the most common signs of aging including brightness, firmness, fine lines, wrinkles, dark spots and sunspots." Also, vitamin C isn't the only perk you get from this powerhouse skin care product. There's also a blend of botanical hyaluronic acid and vitamin E.

Those with sensitive skin particularly love this vitamin C serum as it's fragrance-free and fully plant-based with no synthetic color additives or stabilizers. The TruSkin Topical Vitamin C serum's active botanicals like aloe vera, MSM (methylsulfonylmethane), botanical hyaluronic acid, witch hazel and jojoba oil also combine to create a "silky smooth" texture "that can be used day or night."

With more than 45,000 five-star reviews on Amazon, this serum is one of the retailer's No. 1 overall best-selling products, with some shoppers claiming it's the "best $20.00 you'll spend."

"The results are unbelievable," one shopper wrote. "With or without makeup, my skin is bright, smooth and my spots are disappearing. Your palms get softer too. I guess the residue on the palms makes it soft and supple."

Another shopper dubbed the TruSkin Topical Vitamin C Serum her new "holy grail," explaining, "It has completely transformed my dull, lifeless skin. My complexion has improved tremendously. My face appears brighter, and my stubborn acne scars are fading."

Shoppers also rave that this product helps in reducing the appearance of large pores and dark under-eyes, with one highlighting, "My pores are smaller, and my skin is brighter and more even! The skin around my eyes is looking brighter and firmer, so I think I have found my weapon of choice to continue to fend them off!"

The only con shoppers seemed to express about this product is that, after seeing the impressive results after just a few uses, they "went through the bottle way too fast."
