What it is
This white pearl (*1) serum leads to firm, radiant, and ageless skin. Formulated with a high concentration (*3) of 10,000 ppm of glutathione (*2) with a purity of over 98%. It powerfully addresses dry, dull skin, moisturizing it and restoring a firm, radiant skin like white pearls (*1). It also contains a luxurious blend of carefully selected beauty ingredients, including niacinamide (*4), retinol palmitate (*2), sodium hyaluronate (*4), and ceramide NG (*4). Its amphiphilic design allows it to blend with both water and oil, quickly and steadily delivering skincare ingredients to the skin and allowing them to penetrate deep into the stratum corneum. Its smooth, non-sticky texture blends easily with the skin and does not interfere with subsequent skincare products. (*1) Refers to the appearance of firm, radiant skin like white pearls. (*2) Skin-conditioning ingredients. (*3) Comparison within the series. (*4) Moisturizing ingredients.
