For me, when they start to be over $80, it’ll make me really scrutinize to see what I’m supposed to be getting for the +$30-50. I’d be willing to spend it if it was the perfect foundation for me (shade, texture, finish, coverage, wear, etc.). I regularly use two shades in a given foundation to help tweak undertones or depth, which often brings the cost of one formula to $80-100 anyway. I think the most expensive foundation I’ve purchased myself is La Mer’s The Soft Fluid.
