ABOUT THE BRAND

MANUCURIST

MANUCURIST

Manucurist is a Paris-born nail colour and care brand rethinking the modern manicure through cleaner formulas, professional expertise and a distinctly French sense of colour.

Its story began in 1996, when Gaëlle Lebrat Personnaz’s mother opened the first Manucurist nail salon in Paris. After a career in luxury fashion, Gaëlle took over the family business and set out to create high-performing alternatives to traditional nail products — easier to use, kinder to nails and more considered in their formulation.

Manucurist approaches nail colour as both beauty and care. Drawing on professional salon expertise, the brand develops routines inspired by skincare — designed not only to colour the nails, but also to strengthen, hydrate and protect them. Innovation is guided by a simple goal: to make manicure rituals more effective, desirable and accessible without compromising nail health

Manucurist formulates with a high proportion of bio-sourced ingredients derived from renewable plant materials such as corn, wheat, cotton, cassava, sugar cane and potatoes. The brand excludes a defined list of controversial substances, particularly those derived from petrochemicals, and all ranges are certified vegan by The Vegan Society. Products are cruelty-free, and the brand continues to replace conventional ingredients with plant-based alternatives wherever possible.

Manucurist’s nail care products and polishes are made in France, with an emphasis on short supply chains and local suppliers. The brand also works with an ESAT supported-employment organisation for packaging and assembly, extending its environmental and social commitments beyond formulation to the wider production process.
