Hyaluronic acid is yesterday’s news. The real hydration heavyweight is polyglutamic acid — a molecule that can hold four times its weight in water.
It’s not just about holding water, it’s about creating a flexible film on your skin that locks it all in. Science is cool.
This is The Inkey List‘s take — a clear, slightly goopy serum for $16.99. I tried it because “four times more hydration” felt like a dare.
3% PGA Complex
The main event. Creates that moisture-trapping film.
1% Hyaluronic Acid
Backup singer. Hydrates the surface layer.
Squalane
The peacekeeper. Softens any potential tightness from the polymers.
It’s a short, focused list. The PGA does the heavy lifting, while a couple of supporting players keep things comfortable. No fragrance, which I appreciate.
- Polyglutamic Acid: Forms a breathable, hydrating mesh on skin
- Hyaluronic Acid: Binds water to skin’s surface
- Squalane: Lightweight emollient to prevent tightness
- Propanediol: Humectant and solvent derived from corn
Texture is weird — like a slightly stringy, clear gel. Absorbs in about 30 seconds, but leaves a distinct, velvety-slick finish. Not sticky, but you feel it.
After two weeks, my makeup sat differently. Better? Sometimes. But if I used too much, my foundation would pill. A classic case of less is more.
My skin was undeniably more hydrated — fine lines looked softer for a few hours. Zero irritation. But it’s a surface-level quench. Don’t expect long-term repair.
It’s a potent hydrator that delivers on its one job. Not a miracle, but a really smart, affordable tool for your routine.
