Ingredient sourcing
Every ingredient, traced to its source.
Some common cosmetic ingredients can come from animal sources: glycerin, fatty acids, collagen, gelatin, keratin and some emulsifiers. We choose plant, mineral or synthetic sources, or halal-certified animal sources, and collect certificates for each raw material.
