Dermatologist-approved and known for treating skincare concerns like wrinkles, uneven texture, and dark spots, the antioxidant is a featured ingredient in many skincare products. Deciding on a vitamin C serum that's right for you comes down to personal preference and the results you hope to see with use, but you can currently shop an Amazon shopper-approved option for just $20. More than 7,500 Amazon shoppers have given the LilyAna Naturals Vitamin C Serum a five-star rating. After a week of use, one reviewer reported that their "pores appear smaller," leaving their "skin tighter and smoother," while another said they noticed a difference in three days, writing, "I've seen a reduction in redness, faster recovery, and an overall reduction in breakouts." Normally, you'd have to spend $30 to try the serum for yourself, but Amazon is currently offering a bottle for just $20. Courtesy Shop now: $20 (Originally $30); amazon.com Inside the bottle, you'll find a serum containing 20 percent vitamin C. The featured ingredient is formulated alongside other skincare superstars like aloe leaf juice, vitamin E (known for brightening skin tone and treating aging skin), and jojoba oil. The water-based formula can be used as part of your morning and evening skincare routine and can also be worn under makeup. As board-certified dermatologist Dr. Michele Henry previously told InStyle, "The antioxidant activity of vitamin C protects against UV-induced damage caused by free radicals, which will prevent accelerated aging and skin cancer. It also boosts firmness by regulating collagen production." (Note: Vitamin C is generally tolerated by most skin types, but if you're using retinol or AHA and BHA acids, you may want to speak with a skincare expert about it before you try it. As Henry explained, mixing these products can cause irritation or reduce their effectiveness.) "Believe the hype — this product is amazing," one shopper wrote. They added, "After about a week of use, my 51-year-old skin started to look fresh and plumped. The tiny lines around my lips all but disappeared. The redness around my nose and cheeks is reduced. My skin has a healthy glow and feels great. I absolutely love this product." Along with improving fine lines, adult acne, and general skin texture, others have found success in reducing even deeper wrinkles. "After one week, I can see a difference in the wrinkles. I am 70, so the wrinkles are very prominent, but this serum makes my wrinkles a little less noticeable. My skin looks brighter. I would buy this again," a shopper wrote. They later made an update to their review, sharing, "I have purchased this product often and still love it." Now's your chance to try this serum for yourself while it's on sale. Purchase a single bottle for just $20 on Amazon, or subscribe and save even more with a recurring order.
