Instanatural’s Anti-Wrinkle Anti-Aging Serum had thousands of rave reviews on Amazon—and only costs $17.
In addition to the main attraction, retinol, this serum also has hyaluronic acid and argan oil for intense hydration, plus niacinamide to restore the skin’s barrier and prevent environmental damage. It’s even got vitamin C to brighten and even the skin’s allover tone. A 2005 study even found that participants who used a blend of the two ingredients saw a significant change in signs of aging and photo-aging. Another studyfound that applying a retinol–vitamin C complex greatly increased the amount of skin surface lipids in menopausal female participants, helping to create a natural barrier against aggressors as well as retain moisture in the skin.
With over 1600 five-star reviews on Amazon, we’re convinced this won’t be another bottle of serum that makes it into the beauty product graveyard. Amazon shoppers rave about how much their skin has changed in terms of fewer signs of aging and an overall dewier, more glowing complex.
