IUNIK Beta-Glucan Water Barrier Moisture Daily Sunscreen is a multifunctional Korean skincare product formulated with SPF 50+ and PA++++ protection. The key ingredient, beta-glucan, is a natural polysaccharide derived from yeast or oats, known for supporting the skin’s moisture barrier and providing hydration. This sunscreen combines sun protection with moisturizing, lifting, and plumping benefits, aiming to maintain skin’s water balance throughout the day. The formula is designed to be matte and leaves no white cast, making it suitable for application under makeup or alone. It is vegan and avoids animal-derived ingredients. The texture is lightweight and absorbs quickly without greasiness. This daily sun cream is crafted for multiple skin types, including dry, oily, and sensitive skin. For oily or combination skin, the matte finish helps control shine without stripping moisture. For dry skin, the beta-glucan provides sustained hydration without a heavy feel. Sensitive skin may benefit from the absence of common irritants often found in conventional sunscreens, though individual sensitivities should always be considered. The product is intended for everyday use as the final step in the morning skincare routine. It does not rely on synthetic fragrances or harsh chemicals that might disrupt the skin barrier.

Instead, it focuses on gentle, effective protection and water retention. The lifting and plumping effect is attributed to the moisturizing properties of beta-glucan, which helps maintain skin elasticity over time. No exaggerated claims are made regarding instant or dramatic results. The sunscreen is part of IUNIK’s focus on accessible, ingredient-driven skincare. It is best suited for individuals seeking a daily sunscreen that hydrates, protects, and leaves a natural, non-shiny finish.
