PRODUCT DETAILS

Hello, radiance. VM pairs 5% sodium ascorbyl phosphate, a vitamin C derivative, with 1% MSM in a serum made to support a brighter, more radiant and even-looking complexion. It’s a focused choice when dullness and uneven-looking tone are at the top of your list.

The clear, watery texture absorbs quickly. Beyond visible tone, the formula is designed to improve the look of skin texture and help defend skin’s appearance from daily environmental stressors. That brings tone, texture and antioxidant care into the same step.

Ferulic acid adds antioxidant support and helps enhance vitamin C’s effectiveness in this formula. Vitamin E contributes moisturizing and antioxidant support. Betaine, aloe vera and sodium hyaluronate round out the formula with moisturizing support, while betaine also adds a soothing role.

The serum is designed for all skin types, including sensitive skin. It has no added fragrance, parabens, phthalates or GMOs.
