1.Jelly That Melts

I scooped this out with my finger and it literally jiggled. Not a gel — a wobbly, translucent cube of hydration that broke apart the second it hit my skin.

That texture gimmick? It’s not a gimmick. The jelly format locks the multi-weight HA molecules in a stable matrix so they don’t evaporate before they penetrate. Smart, actually.

2.🧴What’s In The Cube

It’s Ulta Beauty‘s new SOS serum — $38 for 1.7 oz, which is fair for a texture this weird. They claim it hydrates 10 layers deep using different molecular weights of hyaluronic acid.

1

Jelly-to-silk transition

Scoop it, rub it, and it liquefies into an oil-like slip in under 5 seconds.

2

No tacky film

Most HA serums leave that gluey residue. This one doesn’t. It vanishes.

3

Pump-free design

You dip in. It’s messy but satisfying. Keep it on your bathroom counter, not in a drawer.

3.💧What’s Actually Inside

Five molecular weights of HA plus polyglutamic acid — which holds more water than HA itself. The jelly format keeps them stable without alcohol or silicone.

  • Sodium Hyaluronate: Small molecule penetrates deep
  • Hydrolyzed HA: Mid-layer plumping
  • Polyglutamic Acid: Locks moisture on surface
  • Panthenol: Calms irritation from acids or retinoids

4.🫧The Feel Test

It’s cold. Like refrigerated jelly on a hot face. Spreads with zero friction — you only need half a pea-sized scoop. Absorbs in 10 seconds flat, leaving skin bouncy but completely bare to the touch.

Week 2 surprise: my foundation stopped pilling. I didn’t expect a hydrating serum to fix that, but the lack of film meant my sunscreen and makeup actually sat on top instead of sliding off.

💡

One Thing: Apply to damp skin. The jelly grabs water molecules from your face, not the air — this stops trans-epidermal water loss better than patting dry first.

5.👃Did It Actually Work?

My fine lines around the nose looked softer by day 5 — not gone, just less etched in. But my oily T-zone stayed oily. It hydrates, it doesn’t regulate oil.

Buy if
You’re on tret or retinol and need hydration that doesn’t sting or sit heavy.
⏭️

Skip if
You hate sticky fingers from dipping into jars. This requires a scoop or clean hands.
💰

Worth it?
$38 for a texture experience that actually delivers. I’d repurchase before my $60 HA serum.

It’s the most fun I’ve had with hydration since discovering sheet masks. And unlike those, this one actually sinks in.
