Maruderm Glutathione Brightening Milk Serum is a lightweight moisturizer-serum designed to support a radiant and even-looking complexion. Formulated with glutathione, alpha arbutin, and licorice extract, this 1.0 fl. oz. (30 mL) product targets areas of uneven skin tone and dullness. Glutathione is a naturally occurring antioxidant that helps protect the skin from environmental stressors, while alpha arbutin and licorice are known for their brightening properties and ability to assist in reducing the appearance of dark spots. The milky serum texture absorbs quickly without leaving a greasy residue, making it suitable for layering under sunscreen or makeup. This product is ideal for individuals seeking a simple, daily brightening step that can be incorporated into both morning and evening routines. The formula is gentle enough for most skin types, including sensitive skin, as it avoids harsh ingredients and focuses on botanical extracts. With a practical 30 mL size, it offers an accessible option for those who prefer a straightforward approach to achieving a more luminous and even skin tone. The serum’s lightweight consistency makes it particularly well-suited for normal, combination, or oily skin, but it can also be used by drier skin types when paired with a richer moisturizer. By combining brightening actives in a non-sticky, fast-absorbing base, this product provides a functional addition to any skincare regimen without unnecessary complexity or inflated claims. The pricing reflects a focus on value, delivering key ingredients without premium markups. For best results, apply a few drops to clean skin before moisturizer, and follow with sun protection during the day.
