This deep moisture serum is formulated to support dry and dehydrated skin through a combination of key ingredients including algae extract, niacinamide, and arginine. Algae is used in the formula to help maintain skin hydration and support the skin’s natural moisture barrier. Niacinamide contributes to a more even skin tone and helps improve the appearance of texture over time, while arginine works to reinforce the skin’s protective barrier and soothe dryness. The serum is designed to deliver long-lasting hydration without a heavy or sticky feel, making it suitable for daily use as part of a Korean skincare routine. It aims to promote a smooth, radiant complexion often described as a glass skin look, focusing on surface refinement and moisture retention. The formula is fragrance-free, which reduces the likelihood of irritation for those with sensitive or reactive skin types. This product is particularly suited for individuals with dry skin, compromised barrier function, or those seeking a gentle hydrating step in their skincare regimen. The texture is lightweight and absorbs quickly, allowing it to be layered under moisturizers or makeup without interference. At 50ml (1.69 fl.oz.), the serum offers a practical size for regular application. It avoids common irritants such as artificial fragrances and is built around a neutral, barrier-friendly approach to hydration. The combination of algae and niacinamide provides both immediate and cumulative benefits for skin that feels tight or lacks moisture. This product can be used in both morning and evening routines, and is compatible with other skincare products. It does not promise dramatic transformations but instead focuses on consistent, gentle care for dry and dehydrated skin conditions.
