Let's face it. Good skincare can cost you. That's why I like to take advantage of sales on beauty items whenever I can, and right now Amazon's discounting a vitamin C face serum you can't pass up. The TruSkin Vitamin C Serum with hyaluronic acid is on sale for 33 percent off.

The antioxidant can offer a ton of benefits from evening skin tone and reducing hyperpigmentation to stimulating collagen production and reducing signs of aging, like fine lines and wrinkles.

The TruSkin serum is also made with a plant-based formula and is certified cruelty-free by Leaping Bunny. It's free of parabens, fragrances, synthetic colors, and other added chemicals that may be harmful to your skin.

Customers on Amazon say it really does work to brighten the skin.

"I purchased this in hopes it could help even my skin and brighten my dull color up. I didn’t have high hopes and figured at worse I wasted $20. But boy have I been surprised. Within a week I had a noticeable brightness and clarity in my skin color/appearance. I put this on, let it dry for a minute, then lather a homemade coconut oil/cocoa butter/essential oil lotion on top and my skin is just LOVING it," wrote one reviewer.

Another reviewer was unsure the serum would work on her skin tone, but she was surprised it did.

"The results are unbelievable. I was a bit skeptical because all the reviews were from Caucasian women. I was slightly worried that my skin would not respond as well but I was quite mistaken. With or without makeup, my skin is bright, smooth and my spots are disappearing," the customer wrote.

Though the serum is usually $30, you can grab a a bottle for just $20 right now.
