We source our ingredients from trusted providers around the world; most come from the highest-quality purveyors in Europe and the USA.We choose ingredients based solely on their hypoallergenicity, efficacy, quality, beneficial merit, and sustainability...not on their aesthetic properties or other "marketable" claims.This punctiliousness is heightened by our policy of using the least amount of ingredients possible (which helps increase a product's hypoallergenicity). So our ingredients give maximum benefits without having to pile them on, a practice that increases the likelihood of irritations and cross-reactions.Our "skingredients" are so fine (we patch test each and every one!) that we've proudly displayed them on our labels since we started in 1979...long before U.S. and other countries' legislation mandated that ingredients be disclosed on cosmetics products.
