Our Take
A proof-of-concept: serious ingredients, serious price, seriously beloved.
Five types of hyaluronic acid in one $9.90 bottle—designed to hydrate every layer of skin at once.
The Ordinary has built a following on stripping away marketing bloat and delivering active ingredients at prices that don't require a justification speech. This serum is their textbook move.
On price
At $9.90 for a multi-acid, ceramide-rich formula, this is genuinely hard to beat—most competitors charge 3–5× more for comparable ingredient density.
The Criteria
What to weigh
01
Multi-Depth Hydration System
5 types of hyaluronic acid
Rather than relying on one molecular weight, this formula uses multiple sizes to penetrate different skin depths. That's the kind of layered thinking you'd expect from a pricier brand—here it costs pocket change. The result is moisture that settles in and sticks around.
02
Barrier Support
Ceramides + Pro-Vitamin B5
Ceramides are structural—they lock moisture in and reinforce your skin's natural barrier. B5 works alongside them to help your skin hold onto that hydration longer. Together, they turn a simple serum into a mini moisture architecture project.
03
Texture & Ritual
Lightweight serum, 1 Fl Oz
This is a thin, runny liquid that absorbs fast and plays nicely with other products. Apply to damp skin for maximum penetration. It's the kind of serum that vanishes into your routine without fanfare.
Who it’s for
Anyone with dry or dehydrated skin, especially those layering actives who need a workhorse hydrator that won't irritate or complicate their regimen.
