Query: dont waste money

i bought this product in an attempt to do at home what i get done at the derm's office during a microderm apprasion. it was lame. i could have gone to target and bought just a quantity of 1 for $3. in this purchase they send you quantity of 2. why would you need 2? plus didnt work for me.
