Take the skin testDiscover the ultimate daily defense with iUNIK Beta Glucan Barrier Sunscreen, a lightweight K-beauty SPF 50+ PA++++ formula designed to protect and nourish sensitive skin without white cast or greasiness. Infused with Beta-Glucan for deep hydration, Aging-Shield Peptide™ for firming, and GreenDiol® for moisture retention, this vegan sunscreen strengthens the skin barrier, soothes irritation, and delivers a matte, serum-like finish that blends seamlessly under makeup.
Beta Glucan Barrier Sunscreen is a lightweight sunscreen from IUNIK. Its job is UV protection, with the rest of the formula working on hydration. The ingredient list runs to 42 ingredients, each broken down in full below.
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Silicones in the formula tend to give a smooth, blurred finish and help it grip under makeup. Hydration is handled by Propanediol, Ethylhexylglycerin and Panthenol, humectants that pull water into the upper layers of skin rather than sealing it there.
It is a chemical (organic-filter) sunscreen, using Uvinul T 150, Uvinul A Plus, Mexoryl XL, Mexoryl SX and Uvasorb HEB. Between them those filters cover UVB, UVA II and UVA I, so the formula is broad-spectrum in the meaningful sense: it reaches past 340 nm, where the ageing wavelengths sit. Every filter in the formula is photostable, so its protection does not fall away over the first hour in the sun — reapplication is still about sweat, water and rubbing rather than degradation.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Propanediol, Ethylhexylglycerin, Panthenol and Butylene Glycol.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Diethylamino Hydroxybenzoyl Hexyl Benzoate, Allantoin, Panthenol and Beta-glucan.
On richness alone it suits Balanced skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on antioxidant protection, oil control, brightening and tone and cell renewal. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, sulfate-free and dye-free. Those claims come from the ingredient list itself, not from the packaging.
Use it in the morning. In a routine it goes final morning step, before makeup. Apply about two finger-lengths for the face and neck — under-application is the single most common reason sunscreen underperforms. Reapply every two hours of sun exposure, and after swimming or towelling off. Let it set for a couple of minutes before makeup so it does not pill.

Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
Based on the curated benefits documented for this product's ingredients.
Attracts and locks in moisture to keep skin plump and dewy
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Calms redness, irritation, and inflammation for sensitive skin
Regulates sebum production to reduce shine and greasiness
None of the ingredients in this formula are associated with these benefits. This is not unusual, as most products are designed to target a limited number of concerns.
Chemical (organic) filter system · broad-spectrum through UVA I
The most efficient UVB absorber available by weight, which is why high-SPF formulas reach SPF 50+ without feeling heavy. Contributes nothing to UVA.
A photostable replacement for avobenzone: it peaks at 354 nm, deep in UVA I, and does not need a stabiliser to survive the day.
Oil-soluble and broad-spectrum, with two absorption peaks covering UVB and UVA.
Water-soluble UVA filter, which is unusual — most UVA filters are oil-soluble.
A photostable, highly efficient UVB filter, usually paired with a dedicated UVA one.

Apply generously: Dispense a sufficient amount of iUNIK Beta Glucan Barrier Sunscreen onto your fingertips or palm as the last step in your skincare routine. Spread evenly: Gently massage the sunscreen over your face and neck, ensuring full coverage for optimal UV protection. Pat for absorption: Lightly pat the product into the skin to enhance absorption and achieve a matte, non-greasy finish. Reapply as needed: Reapply every 2 hours or after sweating, swimming, or towel drying to maintain SPF 50+ PA++++ protection; use daily for best results.
Judged on how rich the formula reads from its ingredient list, it suits Balanced skin best. It is the least natural fit for Dry, Combination (dry) skin.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.

It filters UV with Uvinul T 150 (ethylhexyl triazone), Uvinul A Plus (diethylamino hydroxybenzoyl hexyl benzoate), Mexoryl XL (drometrizole trisiloxane), Mexoryl SX (terephthalylidene dicamphor sulfonic acid), Uvasorb HEB (diethylhexyl butamido triazone).
Yes. Its filters cover UVB, UVA II and UVA I, so protection reaches past 340 nm into the deep-UVA range associated with ageing and pigmentation.
Unlikely. It filters with organic (chemical) filters only, which dissolve into the formula rather than sitting on the surface, so they do not leave a white cast.
It contains none of the filters named in the Hawaii and Key West reef legislation (oxybenzone and octinoxate). "Reef safe" is not a regulated term, so treat that as a fact about the filter list rather than a certification.
Yes. Let it set for a couple of minutes before foundation so it does not pill, and reapply over makeup with a stick or powder rather than rubbing more in.
Every two hours of sun exposure, and immediately after swimming, sweating heavily or towelling off.
