Why we like it.

The reason we recommend a hyaluronic acid serum before a fancier active is that most 'my skin looks off' complaints are actually about dehydration, not aging. A well-formulated HA gives you a visible improvement in a week — brighter, plumper, less crepey — for the price of a coffee run.

The Ordinary's version uses three molecular weights so hydration lands at different depths, not just on the surface. The addition of B5 makes it more comfortable on reactive or newly retinized skin than most first-gen HA serums.

One rule that matters: apply it to damp skin and seal it with a moisturizer. Applying HA to dry skin in dry Michigan air can pull water out of your skin instead of in. Not a defect of the product — a rule of humectants.

Good for
  • Anyone whose skin feels tight, flaky, or dull in winter
  • First-time serum users who want a low-risk, high-visible win
  • Retinoid or exfoliant users who need extra hydration between actives
  • People building a routine on a budget
Skip it if
  • Anyone expecting an anti-aging active — this is hydration, not treatment
  • People who don't have time for the 'apply on damp skin' step
For nine dollars, this bottle changes how a routine feels. Two drops on damp skin, then your moisturizer — that's it.

FAQ

Questions people actually ask.

Can I use it with everything?

Yes — HA layers safely with vitamin C, retinol, niacinamide, and every other active in a normal routine.

Why do people say HA is drying?

Only when you apply it to dry skin without sealing it in. Damp skin + moisturizer on top solves this.

Do more expensive HA serums work better?

For most people, no. The Ordinary version does the same job as $60 versions. Spend the difference on sunscreen.
