Our Founder and Formulator Elly Seymour has dedicated her life to understanding the intricate language of the skin.

Her journey, marked by relentless study and a passion for evidence-based formulation, culminated in the creation of Saint Louve - a cosmeceutical skincare brand that marries luxury with precision, and indulgence with efficacy, founded on over 15 years of in-clinic expertise, extensive clinical trials.

This intense hydrating and superior radiance boosting serum contains 12% Vitamin B3 (Niacinamide) & 1% B5 (Panthenol) to improve moisture levels within the skin, visibly reduce dehydration, fine lines & excess oil. It will also assist to maintain a healthy barrier function and help to reduce trans-epidermal water loss, providing visible luminosity and a more even complexion. In addition, it contains three molecular weights of Hyaluronic Acid and Polyglutamic Acid, which visibly plump the skin and provide immediate and long-term hydration and glow.

suitable for all skin types, including normal, dry, sensitive, ageing, oily skin, and breakout-prone skin.
