We use only pharmaceutical grade or food grade ingredients. Sure, they cost more, but they are worth it, both to us and to you. All of our ingredients are "non comedogenic" (do not clog pores), we don't use animal derived ingredients. We do use "nature identical", which means the chemical makeup of the ingredient is exactly as it appears naturally, but without possible irritants and contaminants. We do not use mineral oil, or lanolin, or waxes, instead we use some of the finest and most expensive natural oils
