Worth it!
This set is pretty worth it to find the serum you like the most, and you'll end up with enough product for months as well.
I ended up liking the Glow Serum: Propolis + Niacinamide more than all the others as it seems to have more results over a week. (I tried each one for a week and am now using interchangeably)
If you don't know what to choose yet this is a great option to start.
