I've gotten some feedback that my concealer formulation doesn't have enough staying power, so wondering what my options are to improve upon that aspect.
My current formula is roughly:
40% Vegetable oils
20% Zinc + Titanium Dioxide
10% Creasperse (a thick castor seed oil, iron oxide pre blend)
6% Propylene glycol
Remaining % Misc
I'm thinking of increasing the amount of Creasperse, although that's a costly route to take, other than that, perhaps adding more powders or even clays could help it stay?
