I used mineral make up on and off since 2000. There are soo many brands that I had tried, I started out with BE, then went to Aromaleigh, Monave, Botany101, Alima, Canary, Jane Ireland, Donna, etc, and even ventured to DIY
Fundamentally the ingredients are similar the % is different. It really depends how "natural" you want the minerals to be. Over the years, I use MMU and switch to off the counter non-mmu products as it gives me more even coverage and now a days I don't use any.
There are alot of Mineral makeup makers out there, find out what works for you and what don't. Main difference is the ingredients, some has bismuth, some don't, some use talc some don't, some uses zinc and some don't. Find out which formulation works for you and what don't.There are some that may make u break out, what works for one person might not work for another.
Because of the high % of
titanium dioxide - it has SPF even the smaller mmu houses, just that it takes money to get it SPF certified & they don't do it as it cost alot more. But mmu does have SPF protection.
Right now when I do use MMU, I stick to Monave. I trust the ingredients used and I know which color and formulation fits me. They do sell their minerals to resellers that package their own brands or for mmu makers to DIY. And no, I do not work for Monave. I am just sharing my mmu experience
