Does anyone know where to buy face masks in Brandon?

You may need to be a little more specific on the type of facemask.  
 
Are you looking for plastic ones that can be painted however you want?  
 
Are you looking for masquerade masks?  
 
Are you looking for the facemasks the hospital asks sick people to wear so they don't spread jerms?  
 
Are you looking for the kind theives like to cover their face with?  
 
Are you looking for respirator type face masks?

I'm talking about beauty masks. Like mud masks or anything like that to put on your skin.

Wal-Mart sells various kinds of face mask peels in rip open pouches and squeezable bottles.

Walmart, possibly the body shop, winners, shoppers drug mart. That's all I can think of right now

Some hair salons sell good quality skin care products so possibly would have facial masks and creams. Pantages and Straight Up both sell the Eminence line of products which I believe has masks. I expect other salons will carry other lines/brands of salon-quality products which may include what you are looking for. You could also try Daydreams Spa which was to open yesterday at 801 - 10th Street (former location of Escape Spa) - they probably carry skin care products.

I like the ones from here the best. 3 for $5. I prefer the sheet masks over the cream kind.

Two farm kids have some great reasonably priced masks, and the body shop in the mall just came out with a new line of face masks for all kinds of needs and skin types!

You could make a mask yourself. Sometimes purchasing these mask can be a make or break situation. Do some research and based on the reason for the mask, you can make your own. You are guaranteed what goes in the masks.  
 
There are lots of youtube videos!

Our riverbeds tend to have a high amount of clay in deposits along the way. You can dig that stuff up, and rub it all over your parts. Or, go pick up some of the nice packs at shopper's for a bargain.  
 
If you were looking to make a nice mask for your masquerade's, or costume parties you can pick up the plaster of paris rolls at Michael's, and use some chicken wire to make some funky designs. They're good for a project with the little ones too!
