Pai is an Instagram beauty brand I can get behind. After falling for the sponsored post I repeatedly got targeted with, I bought the bestselling Rosehip BioRegenerate Oil and instantly noticed how it made my skin glow. If you've been seeing it everywhere as well, now's your chance to try it for yourself as part of the Pai Three Piece Water Astrological Gift Set (£15, originally £22) at TK Maxx.
