ABOUT MARIE VERONIQUE
Marie-Veronique Nadeau is a chemist who founded Marie Veronique in 2002. An inventor at heart who suffered from teenage acne, she was moved to create her own products when she could find nothing on the market that was clean and effective to address her rosacea. From there, she went on to develop a line for acne and was one of the first to formulate a non-nano zinc oxide sunscreen. She continues to lead the way towards safe yet effective skincare, determined to move an industry ensconced in hype into the realm of science. She is a trained esthetician, holds degrees in Math and Science, and is a former high school chemistry teacher. She collaborates with her daughter, Jay Nadeau, physicist and bio-medical engineer, to carefully choose each ingredient in her products to solve real skin issues and address the causes of aging at the source.
Our vision at Marie Veronique is to deliver superior, non-toxic skincare drawing on nature’s genius and the brain of science through innovative formulations. Achieving optimal skin health and healing real skin issues drive us to produce safe products that truly work.

Everyone needs sun protection, but if you’re struggling to control certain skin conditions, it’s particularly important to find the right kind. The primary stressor for inflammation-based conditions like photoaging, rosacea and hyperpigmentation is—you guessed it—sun exposure. Here’s are the most common sun traps and how to avoid them.
UVB—Burning rays which penetrate to the epidermis cause redness and itching, damage DNA and are linked to squamous and basal cell carcinomas. At their peak between 10am to 4pm, UVB rays reflect off shiny surfaces, making snow, sand and water excellent sunburn accelerators.
UVA—Aging rays penetrate to the dermis and cause wrinkles by cross-linking collagen and elastin, and hyperpigmentation because they turn melanin darker. Present from sunup to sundown, they penetrate clouds and glass.
Rosacea involves a complex interaction of different factors and pathways leading to a chronic inflammatory and vascular response. A major instigating factor is UVB/ UVA exposure.
UVB rays penetrate to the epidermis and increase secretion of two factors: vascular endothelial growth factor (VEGF) and fibroblast growth factor 2 (FGF2). These increase vascularization of the skin and cause swelling.
UVB triggers activation of vitamin D3, which directly induces the expression of cathelicidin. Cathelicidin is an antimicrobial peptide that, when processed by rosacea-type skins results in vasoactive and pro-inflammatory peptides and peptide fragments.
UVA and UVB—UV irradiation also produces reactive oxygen species (ROS), which cause vascular and dermal matrix damage by stimulating enzymes, which break down collagen in the dermal matrix. A damaged dermal matrix may permit leakage and accumulation of inflammatory mediators and prolonged retention of inflammatory cells.
Many people with rosacea simply do not tolerate sun very well at all and are advised to limit their sun exposure. However, because most of us like a little sun, these suggestions will help boost your tolerance.
UVB stimulates melanin biosynthesis.
UVA turns melanin darker.
