Published by SKINĒDIT PARIS. Our journal connects research with formulation choices, while keeping the scope and limits of each study visible.
Finished-product research
What was tested in people, with which formulation, under what study design? Those details remain part of the result.
Ingredient research
A study of a defined ingredient can inform its selection. It does not automatically establish a result for our finished formula.
Mechanisms and context
Laboratory findings and biological explanations help frame a question. They do not establish a visible benefit in people.
Limits and uncertainty
Population, duration, dose, comparisons and unanswered questions matter. References and evidence notes are included in the articles.
Intelligence Letters
