The $15 'holy grail' serum Amazon shoppers swear by to banish dry skin

Whether you suffer from dry skin year-round or trying to recover from winter’s drying effects, there's a serum out there to help.

According to thousands of Amazon shoppers, Cosmedica Hyaluronic Acid Serum ($15) is a total game-changer for your skincare routine. "My skin hasn't looked this good in years," raved one 5-star reviewer who calls it a "holy grail" product. Some fans of the serum recommend using it alongside a derma roller or layering it under a rich cream. Either way, it’s a favorite among shoppers and boasts over 7,400 reviewers.

The product itself is pretty straightforward: It harnesses the power of hyaluronic acid to deliver a refreshing dose of moisture to the skin. The popular hydrating ingredient plumps skin, diminishing the look of fine lines and has proven long-term anti-aging benefits. Cosmedica's formula is vegan and free of any parabens, oils, dyes, fragrance or fillers.

"I have very sensitive, over-dry skin with mild eczema," explained one user. "After trying this hyaluronic acid, I've actually just tossed all my old bottles of face crap ... It's amazing."

"For very dry and/or mature skin, you can’t beat this product," added another.

As for its anti-aging benefits, reviewers praise skin's overall improved appearance with continuous use.

"This stuff is seriously amazing!" wrote a happy customer. "The biggest change is how luminous my skin looks. I'm a 40-year-old woman, and my skin looked dull previously. My pores are less noticeable now, and the hyperpigmentation is almost gone!"
