A quality skin-care product can easily set you back $50 or more, to say nothing of pricey in-office treatments, which can run well into the hundreds. At $19 — nearly 40% off — this No.1 bestselling serum is a steal in comparison and would be a bargain even at its full price of $30.

TruSkin's plant-based formula has a blend of vitamins C and E that aims to brighten skin, plus hyaluronic acid for moisturizing. It's well-known that hyaluronic acid is a skin-hydrating wonder, thanks to its ability to hold up to 1,000 times its weight in water. When added to the skin, this capability helps it lock moisture deep inside of pores. Hyaluronic can also help stave off signs of aging like fine lines, wrinkles and a dull complexion, and helps leave skin with a more plump, youthful look.

TruSkin is also packed with skin-soothing botanicals, such as aloe vera and organic jojoba oil. Many of us have used aloe to calm our skin after a long day in the sun, and jojoba oil is also in the mix to assist in soothing skin while it fights signs of aging.

Shoppers have put TruSkin Vitamin C Serum to the test, and many say they're loving the results.

"I wish I took before and after photos!" one shared in her review. "Since using this product for a few months now, I have noticed my frown lines, crow's feet, and lines around my mouth are slowly fading away. It keeps my skin taut, and I need this at my ripe age of 42."

"I started using this after noticing how my skin was dull and very textured regardless of using retinol, SPF and remaining diligent with my skincare routine," noted another happy shopper. "Now, my skin is more glowy, my breakouts are calming down, and my skin feels less dry! Highly recommended for the price."

"It tightens up the skin on my face and leaves it nice and smooth," said a third five-star reviewer. "Some reviews said it works on dark circles, but I didn't notice any change. It does not moisturize but feels fine after applying sunscreen. I didn't notice any scent, which I appreciated."

Some shoppers felt like the serum seemed to reach its expiration date quicker than stated. Revealed one: "I have to criticize the fact that everything was good with expiration date and the package was new, but the color changed and it seemed to have oxidized, even though I kept it in exactly the proper conditions."

Echoed another: "I’ve bought this serum multiple times and I love it...The problem is that it went bad months before the expiration date. I store it correctly and it all of a sudden became thick and lumpy...This would be a no doubt 5 star if the product lasted at least until its expiration date."

Tired of heavy creams? This serum is designed not to weigh on skin.
