OUR HISTORY

Since 2008, SP Equation has developed recognized expertise in the in vitro evaluation of cosmetic products. Initially specializing in experimental hair evaluation and hair strand preparation, the laboratory has gradually expanded its expertise to two other key areas: sunscreens and makeup products.

Our mission? To support players in the cosmetics industry in the development, validation, and marketing claims for high-performance, safe, and innovative products.

SP Equation is committed to offering customized solutions using a 100% instrumental in vitro approach that complies with ethics and international regulations. Our capacity for innovation, scientific rigor, and attentive listening skills allow us to meet the specific needs of each project, no matters of its stage of development.

OUR TEAM

SP Equation is, above all, a close-knit team composed of scientists, technicians, studies managers, and dedicated staff.

Our areas of expertise (hair, sun, makeup, and evaluation support) are led by passionate professionals trained in the latest technical and regulatory developments in the cosmetics industry.

Each team member shares a common vision: to deliver reliable, actionable, and useful results to advance our clients' projects. Collaboration, transparency, and responsiveness are at the heart of our daily operations.
