I bought this because I was bored of hyaluronic acid doing absolutely nothing for my dehydrated skin. Turns out, beta-glucan is the quiet overachiever nobody talks about.
Day one, I put it on before moisturizer and immediately felt my skin drink it in — like a dry sponge hitting water. No pilling, no sticky film, just a softness that lasted past lunch.
It’s a lightweight, watery serum from Iunik that costs around $17 for 50ml. The claim that got me? “Daily moisture without heaviness.” I call bullshit on most serums saying that. Not this one.
Watery-Gel Texture
Feels like a slippery, thin gel that disappears in about 10 seconds — no tacky residue.
No Fragrance, No Dyes
Zero perfume. Zero color. Just a faint, clean “nothing” smell that my sensitive skin thanked me for.
Absorption Speed
I timed it. 12 seconds until my skin felt bare again — but in a hydrated way, not a “did I even apply it” way.

It’s basically a one-trick pony, but that trick is good. Beta-glucan (from mushrooms) is the star, pulling moisture in and locking it there without the tightness that hyaluronic acid sometimes leaves behind.
- Beta-Glucan: Holds 20% more water than HA, minus the sting
- Panthenol: Calms redness and repairs your barrier
- Allantoin: Soothes irritation and softens rough patches
- Sodium Hyaluronate: Small-molecule HA that actually penetrates deeper

First impression? It feels like silk water — slippery but not slick. My skin looked dewy within 5 minutes, but not greasy. That glow lasted about 4 hours, which is more than I can say for my old $40 serum.
Week 2, I noticed my forehead texture was… gone. Those tiny bumps that makeup always clung to? Smoothed out. Week 3, I got a compliment from my esthetician asking if I’d gotten a facial. I hadn’t. The unexpected part? It made my sunscreen sit better — no more pilling with my SPF.

Fine lines around my eyes didn’t vanish, but they looked plumper by day 20. My oiliness balanced out — less shine by 3pm, but not dry either. The hydration lasted a full 8 hours, though I still needed moisturizer on top in my dry climate.

This is the serum I reach for when my skin is acting fussy and I need it to just behave. It’s not flashy, but it’s reliable — and honestly, that’s better.
