Everyone says HA at night. They’re wrong.
It’s a humectant — it pulls water from the air into your skin. The air is drier at night, especially with AC or heat on. It can actually pull moisture *from* your skin if you’re not careful.
It’s the $8.90 serum from The Ordinary. The claim? Simple, effective hydration. No frills.
Hyaluronic Acid 2%
A molecule that holds up to 1000x its weight in water.
Vitamin B5
Helps support the skin barrier — makes the hydration stick.
The Vibe
Clinical. No scent. It feels like you’re doing skincare homework.

It’s not just one type of HA. They use a blend of different molecular weights. Low weights go deeper, high weights sit on the surface.
- Low-Molecular HA: Can penetrate surface layer
- High-Molecular HA: Forms a hydrating film on top
- Crosspolymer: A fancy, longer-lasting form of HA
- Vitamin B5 (Panthenol): Soothes and helps repair

Weird texture. Slightly sticky, viscous slip. Absorbs in about 30 seconds if your skin is damp — leaves a faint, tacky film.
After two weeks, that morning film became my secret weapon. Makeup grips to it like glue. At night, that same tackiness just felt annoying on my pillow.

Plumper look by noon? Yes. Fewer dry patches under foundation? Absolutely. Did it cure my dehydration lines? No. It’s a hydrator, not a time machine.

A brilliant morning workhorse. Save the richer treatments for night.
