Take Jelly Ko’s Korean-style skin analysis to discover which ingredients and products suit your skin type, concerns and goals.
START SKIN ANALYSISWhat Is Beta Glucan?
Beta glucan is a natural ingredient derived from the cell walls of mushrooms, oats and yeast. In Korean skincare, it’s most commonly used for hydration and barrier support.
It’s often compared to hyaluronic acid because of its strong moisture-binding abilities, but many people find beta glucan feels even more comforting and soothing on sensitised skin.
Literature also suggests beta glucan may help reduce visible redness and support skin recovery after irritation.
What Does iUNIK Beta Glucan Serum Do?
As the name suggests, the serum focuses heavily on hydration and moisture retention.
Despite the thick texture, it absorbs surprisingly quickly into the skin without leaving behind a sticky or greasy finish.
It’s designed to help with:
- Dry patches
- Barrier damage
- Skin sensitivity
- Dehydration
- Rough texture
