Ma'am, Monistat gel is NOT a substitute for Smashbox! People say it 'has the same ingredients', but it doesn't!
These are the Smashbox ingredients- Cyclopentasiloxane, Dimethicone Crosspolymer, Dimethicone, Trisiloxane, Silica, Dimethicone/ Vinyldimethicone Crosspolymer, Ethylhexyl Salicylate, Retinyl Palmitate, Tocopheryl Acetate, Carthamus Tinctorius (Safflower) Seed Extract, Propylene Glycol, Water (Aqua, Eau), Vitis Vinifera (Grape) Seed Extract, Cola Acuminata Seed Extract, Camellia Oleifera Leaf Extract
And these are the Monistat ingredients- Cyclopentasiloxane, Dimethicone, Dimethicone/Vinyl Dimethicone Crosspolymer, Silica, Tocopheryl Acetate, Trisiloxane
They share some ingredients, but they are in different quantities and Smashbox has many more ingredients. Here is a comparison of the two- [link]
I don't know why on earth anyone would consider it an actual alternative.... Basically, it is like saying that since chlorine shares an ingredient with salt, it should work as a substitute. Please don't try putting chlorine in your food instead of salt and please do not use chaffing cream on your face!
