This should really help your friend out tremendously.

Oh, hey! You're back! You even have Lisa's treasured make-up kit! That's incredible! With this, now, I'll surely be able to drastically change my look! Thank you sooo much! I am so grateful that you have done everything you can to help me get back on my feet. There is no way I can really pay you back for all the great things you did for me, but here's a start. Please take it! Anyway, you'll hear this a lot of times, but THANK YOU!!
