ACETONE in skin care product?

My mom & i, are testing a beauty product recommended by my Mom's friend. her skin has noticeably improved since the last time we saw her. according to her she's been using that product for 8 days now. her friends, also using the same product, are getting the same good results. today is our first night to use the product, but we have already noticed 2 things.

1.) It has the stench of acetone smell
2.) One of its ingredients is acetone. to be exact, its ingredients are:

ACETONE, floupolymer, ACRYLIC POLYMER, tocopherol ACETATE (Vitamin E), Vitis Vinera (Grapes), Seed Oil Fragrance.

i don't like the sound of ACRYLIC POLYMER. Acylic is found in paint right?

So what about it? haven't heard Acetone in skin products before. tried searching it on the internet but found none. what good can acetone do for skin>? if its harmless on skin, will it be not hazardous to one's health, lungs to be exact?
