Our story & mission

Grounded in science, guided by integrity.

Cosmetic Science Lab grew from a simple belief: brands of every size deserve the same quality of formulation science, testing and regulatory care that the largest companies take for granted. Built on 15 years of product development at the Guires R&D Innovation Centre, we bring that depth to cosmetics and personal care.

Our mission is to help brands launch products that work, that meet the rules of every market they sell in, and that customers trust, by grounding every decision in published evidence and transparent data.

A word from our founder

Good science, done honestly, is the surest route to a product people trust. Get the foundations right and great innovation follows.

I founded Guires in 2009 with a team of three and a passion for research and analytics. Before that I worked with WHO SEARO and the Indian Council of Medical Research (ICMR), served as visiting faculty at the University of Alabama at Birmingham, and supported several global pharmaceutical clients. Since then the group has grown into six specialist businesses serving researchers, life science companies and consumer brands worldwide.

I founded Cosmetic Science Lab at the Guires R&D Innovation Centre to bring that same research depth to beauty and personal care, giving brands one development partner from the first formula to the finished product. As Chairman of the group, I set its vision and long-term strategy and lead its two divisions, Guires Research Services and Guires Labs, through their chairpersons.

At CSL, I guide the leadership team, the heads of formulation, regulatory affairs, and testing and clinical studies, on direction, scientific standards and client commitments. They lead the day-to-day work with brands, supported by multidisciplinary teams of scientists, clinicians, writers, statisticians and lab specialists in Chennai and Manchester. Together we hold to a culture of evidence, integrity and client partnership, so every product, claim and market file is built on evidence you can check.

Our values

Four commitments behind every product we make

Guires CSL scientists work to four commitments: we prove, we partner, we discover and we deliver. They shape how we design studies, how we work with brands and ingredient suppliers, and how we take a product from first formula to market.

  • We proveWe let evidence, not opinion, decide every formula and claim.
  • We partnerWe work as one team with our clients, openly and honestly.
  • We discoverWe stay curious and turn new science into better products.
  • We deliverWe keep our promises on quality, timing and compliance.
