I Swear by This $10 Hyaluronic Acid Serum to Hydrate, Smooth, and Plump Up My Skin Every Day

Cold winter air isn’t a friend to dry skin.

Although my skin type leans more on the side of combination (which means I experience both dryness and oiliness on different areas of my face), it feels much more dehydrated at this time of year. That’s why I use The Ordinary Hyaluronic Acid Serum every day without fail. It’s a bottle of pure hydration — and it’s only $10 at Amazon. 

I apply the serum during my morning and nighttime skincare routines after cleansing and toning. I rub a few drops of the product between my hands, then pat it all over my face while my skin is still damp. In an instant, my face looks plumper and feels more hydrated. I then wait for the serum to absorb into my skin before following it up with a moisturizer.

The Ordinary Hyaluronic Acid 2% + B5 Serum 

The hyaluronic acid serum is also a favorite for PEOPLE Shopping testers. During their trial, a dermatologist told our editors that hyaluronic acid “can hold up to 1,000 times its weight in water,” which helps hydrate skin, while also encouraging it to produce and retain moisture. 

The Ordinary’s best-selling complex is formulated with five types of hyaluronic acid that can penetrate multiple layers of the skin, according to the brand, offering a deeper, more effective boost of hydration. It also has pro-vitamin B5 to thoroughly lock in moisture and ceramides to protect the skin barrier.

Dryness is my main reason for using the serum, but it can also tighten the skin to reduce the appearance of fine lines and wrinkles over time. I’ve also found that it helps in smoothing my skin texture.
