Every ingredient earns its place.
We don’t choose ingredients because they’re fashionable or trending. Every ingredient is selected because it contributes to the purpose of the collection and the experience of the formula.
From botanical oils to carefully chosen actives and formulation essentials, each ingredient has a role. Nothing is included without reason, and every formula is considered as a whole.
