Weleda

Weleda is a natural, organic skin care brand with products that are dermatologically proven effective.
Weleda is a member of the Union for Ethical Biotrade (UEBT), a non-profit organization working for biodiversity and fair trade. This is by far the most stringent certification in natural cosmetics. The products with certification must not have any synthetic ingredients. They must also not contain silicone oils or genetically modified ingredients.
Weleda is organically certified through NaTrue. They examine how the ingredients in the products have been grown biodynamically or organically.
