Cosmetic formulation consulting

Science.
Applied with
precision.

Independent formulation consulting for brands and manufacturers working at the premium end of skincare.

Laboratory glassware

This practice was founded on a simple observation: the most consequential formulation decisions are rarely made in the laboratory. They are made earlier — in how a problem is framed, in which questions get asked, in the assumptions carried forward unchallenged.

The background here is medical and scientific. That shapes the method. Formulation problems in premium skincare sit at the intersection of chemistry, biology, and material science, and they are approached as such — rigorously, without shortcuts.

Consulting engagements cover formulation conception, ingredient selection, stability strategy, and technical review — from initial brief through to finished specification.

01

Formulation conception

Theoretical development of formulation concepts from brief to technical specification. Ingredient selection, system architecture, interaction assessment.

02

Technical review

Independent review of existing formulations or supplier proposals. Stability risk, regulatory compliance, ingredient compatibility, claim substantiation.

03

Specialist consultation

Advisory engagements on specific formulation or regulatory questions. Structured as short, focused sessions for brands or manufacturers who need a second opinion or external expertise on a defined problem.

Premium skincare has a problem with complexity for its own sake. Ingredient lists grow long for marketing reasons, not formulation ones. Claims compound until they contradict each other. The result is products that are sophisticated in appearance and modest in effect.

The work here starts by clearing that. What does this formula actually need to do? What is the simplest system that does it well? Answers to those two questions tend to produce better products than starting from a trend list.

Start with
a question.

Engagements begin with a short conversation about the problem. There is no intake form. Write directly.
