hi everybody! i am looking to oPen a beauty salon offering beauty, nails and spray tanning. i am going to use nsi and leighton denny for the nails, and st tropez for tanning but i am really stuck for which to use for facials and body treatments! any reccomendations would be fantastic! and also, do you know how i can test the products without having to buy them because i dont want to spend a fortune on testing them out to find the range i like. thanks everyone xxxx
