Our Mission

Prose is truly custom hair and skin care made-to-order—just for you. Our line of custom products are made by an in-house, Paris-based R&D team of gifted chemists who combine natural ingredients in innovative ways alongside dermatologists, giving consumers clean skin care, hair care and impeccable results.

At the heart of Prose’s success is Singular, its proprietary AI-powered beauty-tech platform, which has revolutionized personalized beauty at scale.

Prose Values

Intentional Inclusivity

• We know the best ideas come from open minds and willingness to listen. While our products cater to the individual, an invitation into our process is always open to our community.
• We value our differences and diverse backgrounds by communicating openly, managing with transparency and striving to understand one another’s perspective. It’s a key ingredient to our innovation.

Connected Collaboration

• Our strength as a group will outlast our efforts as individual contributors. With offices across countries, staying inventive and agile deepens our clear vision and consistent communication.
• We stay in a spirit of entrepreneurial collaboration: We do not have consensus at all times, but we trust one another to work toward our common goals. Our success is an expression and result of our progressive and gratifying teamwork.

Driven, Together

• We value ownership and coaching that encourages employees to think constructively and creatively about the business. We view employees as leaders and individuals who are accountable, resourceful and responsible. Anyone and everyone is encouraged to lead.
• We recognize that in order to continue thinking one step ahead, we will need to try new things. We strive to provide an open environment that accepts this truth, making space for new ideas to emerge.

Humanity Always

• We assume good intentions in every interaction, keeping ourselves accountable for the climate we create. We seek to understand our co-workers through this lens of conscious benevolence, authenticity and fellowship.
• We operate with the intention of preserving resources, creating an environment we can all live in – for our business and the world. Sustainable care is essential to our ethos as an organization. We take a mindful approach to how we think about our people (employees) and our planet.
