Can the processes (methods) as opposed to ingredients, of producing a beauty product be different enough across different brands/companies to justify the price differences in the same product type? i.e. a eyeshadow product? Especially if the ingredients are very similar?
I wanted to ask this question as a makeup artist I like commented in a tutorial that the reason she liked Dior eyeshadows is they have a wonderful texture. She said that when she asked a cosmetic chemist why they said it was because during its production the product was held at the 'fat combining' stage for slightly longer than is the norm... (???)
I know the amount of ingredients can play a part. High end eyeshadows would have a much higher pigment percentage I imagine, but I'm more interested in knowing if high end companies use more involved methods and this is a reason why their products can be more expensive?
