What's your holy grail off brand/discount store product?

What off brand/discount beauty product can you not live without?

I've recently been buying a lot of Nina pools discount dupes and am absolutely obsessed with finding a deal!!

My personal fav is hypochlorous spray, you can get a big bottle designed for baby care from basically any pharmacy. I use it after sweating, when I've had a break out, even to calm my skin down.
