IUNIK Beta-Glucan Power Moisture Serum is a vegan-friendly Korean skincare product formulated with beta-glucan and seven types of peptides. Beta-glucan, a polysaccharide derived from fermented yeast, is known for its ability to attract and retain moisture, supporting the skin’s natural hydration levels. The inclusion of peptides contributes to the serum’s overall skin-conditioning properties, helping to maintain a smoother and more resilient skin surface.

This serum is designed to provide deep hydration, making it suitable for dry, mature, and sensitive skin types. Its lightweight, non-greasy texture absorbs readily without leaving a sticky residue, allowing it to be layered under moisturizers or used as part of a multi-step routine. The formula is free from animal-derived ingredients and is crafted to minimize potential irritation, relying on gentle, plant-based components rather than harsh additives or synthetic fragrances.

Regular use of this serum may help improve moisture retention and support the skin’s barrier function. The combination of beta-glucan and peptides offers a balanced approach to hydration and skin conditioning without overloading the skin with heavy oils or silicones. The product comes in a 50ml (1.69 fl oz) bottle, providing a practical quantity for daily application.

IUNIK emphasizes straightforward, effective formulations, and this serum reflects that approach by focusing on key hydrating and conditioning ingredients. It does not contain parabens, artificial colors, or mineral oil, and is suitable for those who prefer cruelty-free and vegan skincare options. The serum works well as a hydrating base for normal to very dry skin, and can be used both morning and evening. Its affordable price point makes it accessible for regular replenishment without compromising on ingredient quality. This product is part of a broader Korean skincare tradition that values hydration and skin barrier support through carefully selected active ingredients.
