Ghana is one of the biggest producers of Shea. It’s only grown in a specific climate so it’s not like she’s getting a superior product. There is a difference between West and East African Shea, Eastern is better for skin care.
I’d assume she’s using 100% ingredients (because she’s not breaking down the ingredients further which would be very wrong) so she can rely on the manufacturers’ safety. They’re stable ingredients to mix together so I think the liability would go back to the producer of the components, she probably can’t be touched and has a disclaimer. When I say these are simple mixes, I mean they are very simple.
If you go on amazon or Holland and barret, get yourself a 100% Shea, a bottle of almond oil, orange oil, some zinc oxide powder and charcoal powder you’ll pretty much have her product. This is the kind of thing you would buy at a craft fair, or a hippy shop, just cleverly marketed.
Again, these are proven ingredients, they will be good for many skin types and most people couldn’t be arsed to DIY but we’re not talking about scientific research and technical ingredients, clinical trials that cost the money in other skin care so there’s really no justification for the price.
