BETA-GLUCAN POWER MOISTURE SERUM
Deep hydration without a heavy or sticky finish
This lightweight, transparent gel serum is powered by mushroom-derived beta-glucan, glycerin, Sodium PCA and adenosine. It replenishes hydration, locks moisture into skin and strengthens the natural barrier, leaving skin soft, supple and bouncy without grease, stickiness or a tacky after-feel.
Made with only ten ingredients, the minimalist, dermatologically tested formula absorbs quickly and layers easily in morning and evening routines. It delivers intensive moisturising and soothing care for all skin types, including dry, sensitive, oily and acne-prone skin.

For skin that feels dry even after moisturising
Dehydrated skin can feel tight, look rough and lose its fresh bounce even when it also produces oil. This serum adds concentrated water-binding care before moisturiser, helping skin hold onto hydration without adding a rich coating.
It targets intense dryness, tightness, a compromised moisture barrier, visible redness, sensitivity, fine lines and loss of elasticity.

Why beta-glucan works so well for dehydrated skin
Beta-glucan is a natural polysaccharide that can come from different sources; this serum uses the mushroom-derived variety at 160,000 ppb. Like hyaluronic acid, it acts as a powerful humectant that attracts water without feeling greasy or heavy, slows moisture loss and comforts stressed skin while strengthening the barrier against seasonal changes, pollution and everyday environmental stressors.
Glycerin
Replenishes water in the outer skin layers and reduces the uncomfortable feeling of dryness and tightness.
Sodium PCA
Works with the skin’s natural moisture system to keep the finish smooth and comfortably conditioned.
Adenosine
Improves the look of fine lines, texture and elasticity for a firmer, healthier-looking complexion.
THREE-LAYER MOISTURE CARE
Hydration at the surface, within the skin and across the moisture barrier
The formula addresses three reasons dehydrated skin feels uncomfortable: surface moisture loss, insufficient water within the skin and a barrier that does not retain hydration efficiently.
SurfaceSoftens dry, rough texture
Inner moistureReplenishes dehydrated skin
BarrierImproves moisture retention
Instant comfortRelieves tightness after application
Long-lastingKeeps skin comfortably hydrated
Ten focused ingredients, nothing unnecessary
The minimalist formula concentrates on hydration, texture and barrier comfort. It is free from artificial fragrance, drying alcohol and parabens, with no known pore-clogging ingredients.
Non-comedogenic
Hydrates without known pore-clogging ingredients, making it practical for acne-prone and oily-dehydrated skin.
Fungal-acne safe
A focused ten-ingredient formula suited to routines that avoid common fungal-acne triggers.
Fragrance-free
No artificial fragrance competing with sensitive or reactive-feeling skin.
Alcohol-free
No drying alcohol stripping moisture from already tight or compromised skin.
Paraben-free
A compact formula with only the ingredients needed for hydration, texture and stability.
Clinically evaluated for sensitive-skin confidence
Dermatest, an internationally recognised German research institute that evaluates product safety and efficacy on skin, clinically tested this minimalist formula for sensitive skin. The results found the serum unlikely to cause irritation and awarded it an “EXCELLENT” seal after dermatological testing.
Additional evaluations cover three-layer moisture, instant moisture-barrier formation, skin density, HRIPT, sensitive-skin suitability, eye irritation and 26 common allergens.

One serum for dry, oily, sensitive and acne-prone skin
All skin types need water. Oily skin can still lack hydration; when it is dehydrated, it can compensate by producing more oil. This serum provides the concentrated water-binding step without a greasy or heavy film, while your moisturiser can be adjusted to suit your skin type and climate.
Dry skin
Layer beneath a nourishing cream to reduce tightness, flaking and rough texture.
Oily or combination skin
Beta-glucan attracts water like hyaluronic acid, adding lightweight hydration without the greasy or heavy film that makes humid-weather routines uncomfortable.
Sensitive skin
Use the ten-ingredient formula when a crowded routine leaves skin uncomfortable or reactive-feeling.
Acne-prone skin
Replenish moisture while keeping the routine non-comedogenic and fungal-acne safe.
Skin losing bounce
Beta-glucan and adenosine improve the look of softness, fine lines and elasticity.
LIGHTWEIGHT GEL TEXTURE
Soft, dewy moisture that layers cleanly
The silky gel spreads easily, absorbs quickly and leaves a fresh dewy finish without tackiness. It sits comfortably beneath moisturiser, sunscreen and makeup in the morning, and beneath a richer cream or sleeping mask at night.
Silky gelFresh, easy spread
Non-stickyComfortable under cream and SPF

How to use Beta-Glucan Power Moisture Serum
Cleanse and tone
Apply after cleansing and toning, while skin still feels lightly hydrated.
Dispense a few drops
Place a few drops onto clean fingertips or directly across the face.
Massage and press
Smooth over the face, then gently pat until the gel is fully absorbed.
Seal the hydration
Follow with moisturiser. Finish with sunscreen in the morning or a sleeping mask at night for more intensive moisture care.
For very dry areas: Apply a second thin layer while the first is still slightly damp, then seal it with moisturiser.

iUNIK Beta-Glucan Power Moisture Serum FAQ
What does this serum do?
It replenishes dehydration, locks in moisture, reinforces the skin barrier and leaves dry, rough or tight skin softer, smoother and bouncier.
What is beta-glucan?
Beta-glucan is a mushroom-derived humectant that attracts and retains water while soothing stressed skin and strengthening moisture retention.
Is it suitable for oily or combination skin?
Yes. Oily skin can still lack hydration, and dehydrated skin can compensate by producing more oil. Beta-glucan is a natural polysaccharide; this serum uses the mushroom-derived variety. Like hyaluronic acid, it attracts moisture to skin without feeling greasy or heavy.
Can sensitive skin use it?
Yes. The fragrance-free, alcohol-free ten-ingredient formula has completed Dermatest, HRIPT and eye-irritation evaluations.
Can acne-prone skin use it?
Yes. The non-comedogenic formula contains no known pore-clogging ingredients and is fungal-acne safe.
Can I use it every day?
Yes. The minimalist formula is gentle enough for twice-daily use. Dermatest, an internationally recognised German skin-testing institute, found it unlikely to cause irritation and awarded it an “EXCELLENT” seal after dermatological testing. Apply every morning and evening after toner, then follow with moisturiser.
Is the serum vegan?
Yes. It is EVE VEGAN certified, PETA animal test-free and cruelty-free. The plant-powered formula contains no animal-derived ingredients.
What changed in the 2024 version?
Only the packaging changed. The formula remains the same.
Does it replace moisturiser?
Use it as the concentrated hydration step, then seal that moisture with cream. Choose a light gel cream for oily skin or a richer barrier cream for dry skin.
What should I pair it with?
Pair it with iUNIK Beta-Glucan 3X Barrier Cream when dryness, seasonal changes or environmental stressors leave the barrier feeling weak.
How much should I apply?
A few drops or a pea-sized amount is enough for the face. Add a second thin layer only where skin feels especially dry or tight.
