Hyaluronic acid is the popular kid in hydration. But it’s kind of a diva — sucks moisture from your skin if the air is dry.
Polyglutamic acid is the quiet genius. It holds 5x more water *and* creates a film to lock it in. It’s a moisture magnet with a security system.
The Super Saturated Serum from Glow Recipe. $39. I tried it because “10% Polyglutamic Acid Complex” felt like a serious flex.
The Feel
Sinks in like water — no sticky residue, ever.
The Layering
Plays nice with everything. Vitamin C, retinol, no pilling.
The Finish
Not dewy. It’s a plump, matte-satin — makeup sits perfectly on top.

It’s not a one-ingredient show. The 10% PGA complex is the star, but there’s a supporting cast that does the repair work.
- Polyglutamic Acid: Binds water, forms a hydrating film
- Hyaluronic Acid: Still here, but in 5 molecular weights for depth
- Cica & Peptides: Calms and supports barrier repair
- Snow Mushroom: A gentle humectant that doesn’t feel tight

Texture is wild — like thick water. You feel the slip, then it’s just gone in 15 seconds. Skin feels bouncy instantly.
By week two, my t-zone stopped overproducing oil by 11am. The surprise? It’s almost *too* good under makeup — my foundation sometimes slid off until I used less.

My fine lines looked softer, but it didn’t magically erase them. The real win was lasting hydration through a 10-hour workday in dry office air.
This serum made me question my entire HA stash. It’s smarter, longer-lasting hydration. A legit upgrade.
