But here's the thing — you can actually get a lot of the biggest, most-raved about skincare, haircare and makeup, for under $40. 

We love cheap!

And look, seeing as we're a bunch of insufferable beauty nerds who love a spot of shopping, we've even pulled a whole list together to help you choose.

So, let's get to it, shall we? 

From the beauty editor-approved lip mask, to the clever concealer that covers AND treats pimples at the same time (what a show off!), here's a comprehensive list of affordable cult products you can shop at Sephora.
