C-Therapy Serum

Description

Marie Veronique C-Therapy Serum is a versatile treatment suitable for all skin types, including sensitive, breakout-prone, and allergy-prone skin. Formulated with next-generation Vitamin C derivatives that deliver active l-ascorbic acid, it supports skin brightness, collagen production, and antioxidant protection. Glutathione and alpha-lipoic acid help protect mitochondria, supporting overall skin vitality, while the serum remains free of essential oils and microcidal preservatives for gentle, everyday use.

This dual-purpose serum can be used day and night to support skin balance and comfort. It hydrates and helps improve the skin’s moisture barrier, while promoting a more even complexion, addressing discoloration, and supporting overall resilience for a smoother, refreshed appearance.

HOW TO USE IT

ABOUT THIS BRAND

Marie Veronique is a California-based skincare brand specializing in small-batch, microbiome-friendly formulations that support long-term skin health. Founded in 2002 and headquartered in Berkeley, Marie Veronique combines multidisciplinary research with a commitment to clean chemistry, offering topical solutions for all skin types and tones. With a particular emphasis on the science of age delay, the brand creates products that address a range of skin conditions—including dryness, congestion, and sensitivity—by working with, not against, the skin’s natural intelligence.

The brand was founded by Marie-Veronique Nadeau, a former chemistry teacher and licensed esthetician, whose passion for skin health grew out of a personal search for better aging solutions. Today, the brand is recognized for its evidence-led formulations, thoughtful ingredient sourcing, and transparent production practices. All products are made in-house at their Berkeley lab, ensuring freshness, efficacy, and integrity at every step. Marie Veronique also prioritizes sustainability by using recyclable packaging, minimizing waste in production, and supporting suppliers who share their commitment to environmental responsibility. As a woman-founded and woman-led company, Marie Veronique also champions equity and access by supporting initiatives that empower underrepresented voices in science and wellness.
