Been using this pretty regularly since I bought it about a year ago(?). And I do love many things about many of the oils. To be honest, I haven’t used every last one as there are so many in this set and they last a long long time! I have made lotions, facial tonic, aromatherapy recipes, wound care treatments, salves, spritzers, and more. My problem skin has repeatedly shown drastic improvement each and every time I use a new recipe for skin care. I do not regret buying this large set, and I’m sure I will buy again when I run out.... if I ever do.
