When it comes to hydration, NewBeauty readers know exactly what works. In our recent survey of more than 550 readers aged 23 to 83,* one thing became clear: certain ingredients have earned a permanent place in their routines. From moisture magnets to barrier builders, these are the hydration powerhouses readers trust most—and why.
Hyaluronic Acid
It’s no surprise that hyaluronic acid topped the list. Seventy‑five percent of readers said HA is their go‑to ingredient for hydration—by far the most dominant response.
The appeal is simple: Hyaluronic acid pulls moisture into the skin, gives that immediate plumping effect, and layers well under just about every other product. It’s the ingredient readers trust for dewy, bouncy skin, whether they’re using a serum, cream or even a hydrating toner.

Ceramides
Right behind HA are ceramides, with 40 percent of readers saying they rely on them for hydration support.
Ceramides help strengthen the skin’s barrier—something readers clearly value, especially those dealing with dryness, sensitivity or irritation. These lipids lock moisture in, prevent transepidermal water loss and pair well with active-heavy routines.

Niacinamide
Also at 40 percent, niacinamide ties ceramides as a top hydration staple.
While it’s known for brightening and evening tone, niacinamide’s ability to boost barrier function and improve moisture retention makes it a quiet but powerful hydration player. Readers love that it fits into nearly any routine and helps support the skin long‑term.

Squalane
Twenty percent of readers say squalane is one of their go‑to hydrating ingredients.
Lightweight but nourishing, squalane mimics the skin’s natural oils, making it a favorite for those who want hydration without heaviness or congestion. It’s especially loved during winter or after exfoliation-heavy routines.

Glycerin
Rounding out the list is glycerin, chosen by 15 percent of readers.
While it’s not flashy, glycerin is a hydration staple found in countless formulas. It’s one of the most effective humectants, pulling moisture into the skin and helping it stay there. Readers may not call it out as often as HA, but it’s a behind‑the‑scenes hero.
