Glu Mineral Day Serum is a daily facial serum formulated with zinc oxide and glutathione, designed to offer calming and brightening benefits for sensitive skin. This 0.67-ounce Korean skincare product combines mineral-based ingredients with antioxidant properties to support a balanced complexion without irritation. The inclusion of zinc oxide helps soothe the skin and provides a gentle physical barrier against environmental stressors, while glutathione works to even out skin tone and promote a more luminous appearance over time.

The serum features a lightweight, non-greasy texture that absorbs quickly, making it suitable for use as a makeup base primer. Sensitive skin types may find this formula gentle enough for daily application, as it avoids harsh additives and focuses on minimal, soothing components. As part of a morning routine, it can be applied after cleansing and before moisturizer or sunscreen, helping to calm redness and prepare the skin for subsequent layers of skincare or makeup.

This product adheres to the Korean skincare philosophy of combining efficacy with skin-friendly formulations, offering a simple yet effective approach to brightening and soothing. The 0.67 oz size makes it travel-friendly, while the mineral-based composition aligns with those seeking non-irritating, fragrance-free options. Regular use may contribute to a more even complexion without overburdening sensitive or reactive skin.
