INGREDIENT GLOSSARY
We clearly share what each ingredient we use does, what evidence it's based on, and which product it's in. The full ingredient list is included on each product's packaging.
The scientific basis on which our barrier discourse is based.
The outermost skin layer is often described as bricks and mortar. Corneocytes form the bricks; ceramides, cholesterol and fatty acids form the mortar between them. A healthy barrier holds water in and keeps external stressors out.
The rate at which water evaporates from the skin surface. It is the most established measure of barrier function: low TEWL is indicative of a strong barrier.
The amino acids, PCA and related compounds that hold water inside skin cells. Our amino acid complex and Sodium PCA draw on this natural system to support the skin’s own moisture-retaining capacity.
An active ingredient should be present at a level that serves the formula’s purpose, not simply to appear on its label.
Recurring co-actives in all six products.
