​W. Skin Laboratory White Glutathione Tone Up Cream is a skincare product designed to brighten the complexion and smooth fine lines and wrinkles. This dual-function cream provides an immediate brightening effect upon application. Its formulation includes carbonated spring water, which contains 0.6% carbon dioxide and is sodium-free, making it suitable for sensitive skin. Glutathione, an amino acid known to suppress melanin production, helps in brightening the skin and fading sun spots. Adenosine promotes collagen production and improves skin elasticity, while niacinamide also inhibits melanin production, contributing to a brighter skin tone. The cream also contains MultiEx BSASM Plus, a patented blend of seven plant extracts that calms irritated skin and strengthens the skin barrier. Suitable for all skin types, this cream can be used as a base for makeup. For optimal results, apply to clean skin after cleansing, toning, and applying essence or serum. Gently tap into the skin until absorbed, and follow with sunscreen during the day if required.
