VIT-C for sensitive/symptomatic/aging skin. New/genius C derivatives deliver nourishment, clear + brighten.
This serum is ideal for all skin types, especially sensitive, sensitized, breakout-prone skin. Skin sensitized to Vitamin C find that tolerance levels improve upon gradual introduction. Next generation derivatives are stable, yet deliver Vitamin C in its active form, l-ascorbic acid. The presence of l-ascorbic acid allows optimal collagen production, and provides antioxidant protection and skin brightening effects. Glutathione and alpha-lipoic acid protect mitochondria, increasing age-delay benefits. The serum is essential oil and microcidal preservative-free, making it safe for even the most allergy-prone, sensitive skin, and can be used day and night.
This dual purpose serum protects by day and repairs at night, and is safe for use by all skin types. A good alternative to Retinol for pregnant women.

ABOUT
Marie Veronique is a science-led skincare company grounded in a simple philosophy: tell the truth. They approach skin not as something to correct, but as a dynamic system to support.
Every product is formulated, developed, and tested in their lab using Good Lab Practices, then manufactured in-house under Good Manufacturing Practices (GMP). Their formulations combine essential lipids, microbiome-supportive ingredients, and biomimetic peptides to support skin function from surface to depth, continually refined as science evolves.
Founded in Berkeley, California in 2002 by chemist and inventor Marie Veronique Nadeau, Marie Veronique began with a singular goal: to advance skin health through a deeper understanding of how skin functions. Marie’s ongoing work in research and formulation has shaped the brand into one of the industry’s most respected scientific voices, grounded in curiosity, rigor, and a long view of aging. In 2018, Kristina Holey began collaborating with the brand, joining full-time in 2021 as Director of Skin Health. With a background in science, esthetics, and holistic skin care, she expands their educational foundation and systems-based approach.
