What brand of hair removal lotion is the best?

I Just figured out that hair removal lotion is not cancerous or anything, and that’s a really good thing because its pain free and everything. But i use it on my upper lips, will that cause any harm? And if so, what the best way to take of upper lip hair (at home, little cost, i don’t really care if it hurts, and it had to last a long time) preferrably a hair removal lotion.
Thanks.
