They messed with the bottle. That was my first clue.
The new one is a frosty glass dropper — the old was clear plastic. Aesthetic upgrade, sure. But it means the formula inside is different. And when a cult-favorite gets reformulated, it’s never just about the packaging.
It’s the hyaluronic acid serum everyone and their mom uses. About $30. L’Oréal Paris claims the new one is “more concentrated.” I needed to see if that was marketing or real.
2% Hyaluronic Acid
Same percentage as before — so the “concentration” is elsewhere.
Pro-Xylane
Their patented plumping sugar. This is the new star.
Fragrance-Free
A legit improvement. The old one had a faint scent.

The old hero was pure hyaluronic acid. The new one is a cocktail. They added Pro-Xylane, which is supposed to boost collagen, and adenosine, a skin-calming ingredient.
- Hyaluronic Acid: Binds 1000x its weight in water for hydration
- Pro-Xylane: A sugar molecule that mimics skin’s support structure
- Adenosine: A calming, anti-inflammatory ingredient
- Glycerin: Classic humectant to pull moisture in

The texture is thicker. Less like water, more like a slick gel. Still absorbs fast — about 15 seconds — but leaves a slightly tacky film the old one didn’t.
By week two, that tackiness faded. My skin felt more…bouncy? But also a bit thirstier. I started using a richer moisturizer on top.

Fine lines looked softer. My cheeks had a nice plumpness. But the instant, dewy hydration of the original formula? That’s dialed back. This feels more like a long-game treatment.
It’s a solid serum, but it’s not the same. They traded immediate gratification for longer-term benefits. A strategic shift, not just a new bottle.
