as for me, marykay not wallet friendly. you can find any other product that are way more better and in good price like neutrogena, bio-essence or innisfree or any others. some mary kay products , you buy one mk, can get 2/3 products of other brands but if u insist to buy mk, then it's up to you :)
I go on diet, most of the time.. and refrain myself from shopping. do some job so that can get extra income. May Allah ease our studies, get a better job so we can treat them back :)
