Why is it a good deal? 💰

Quality skin care products can cost a pretty penny — we've tested and picked out the best vitamin C serums which have price tags of up to $84, but if you're new to this game, at just $9 with tens of thousands of five-star ratings, this one is a total steal.

Vitamin C is an antioxidant that reduces damage from free radicals, which are known for accelerating signs of aging. It also helps to stimulate collagen to keep skin looking youthful and plump. But the most common benefit is that it brightens the complexion overall and fades dark spots and hyperpigmentation.

This serum is also packed with other dermatologist-tested ingredients, like organic aloe and jojoba for moisturizing, and witch hazel, which minimizes the appearance of pores. The formula's stellar combination leaves skin hydrated and dewy — sans a greasy finish.

Over 22,000 five-star customers rave about the serum's benefits for the skin.

"It’s magic!" one serum user exclaimed. "My skin felt smoother and brighter after just one use, and has continued to feel great after now a week of using this product."

Even reviewers with mature skin turn to the serum for a restored complexion.

One shared: "This is the best-kept inexpensive secret. I use vitamin C serum, hyaluronic acid serum and the retinol serum from this company, and it is the bomb and so inexpensive! I have used expensive products, and they don't work anywhere near as good as Tree of Life serums. I highly recommend this to anyone and especially people like me over 70. I look like I'm in my 50s."

"So far so good," reported a believer. "Been using it for almost a month now. Helps with my scars and brightens the skin, quite noticeable. I'm 44 and live in a very dry-weather area which normal facial moisturizer cannot help, so this vitamin C helps as another layer of my face routine."

"A fountain of youth," another shopper wrote. "I am almost 50 and have a lot of sun damage ... mostly to my chest area. Wrinkled and crepey, this has made a huge difference in a week! I will definitely be getting more. Maybe by the gallon? Lol."

"My acne spots go away faster and my face looks brighter. I have sensitive skin, and this product does not irritate me at all," wrote another fan. "Doesn’t smell amazing, but I’m glad it doesn’t have added fragrance, since that tends to irritate my skin. Overall I definitely recommend!"

"I have been using it for just over a week, and can truly say that my skin is very soft and even a little plumper," a rave reviewer wrote, adding: "It's thicker, so it takes a bit longer to dry upon contact. Also, it's sticky. Unless I put a moisturizer on after application to mask the stickiness it's a little yuck to touch."

With vitamin C, hyaluronic acid and vitamin E, this serum hydrates skin, helps reduce dark spots and the appearance of wrinkles to leave your complexion glowing.
