Based on Tiffany's review, it is clear that the "Rules Of Mastic Facial Tonic" by Too Cool For School is a highly effective and versatile product. Its hydrating properties and brightening function make it a great addition to any skincare routine. The fact that Tiffany uses it even with a full face of makeup speaks to its lightweight and non-greasy formula. The instant hydration it provides is a major plus, and the fact that Tiffany brings it everywhere she goes shows its portability and convenience.
