I have tried using this a few different ways, and each one was a failure I added a few drops to my hands rubbed them together and then applied to my face like the directions say. Made my makeup look oily and slide right off. So then I tried I'll just add 2 drops one on each side of my face and use a beauty blender, nope same greasy results. How about I add 1 drop to my foundation? It made my liquid foundation separate. So I choose not to try it anymore after 7 attempts. If anyone else has any success let me know. Also because this is so oily it caused me to break out. Something I haven't done in years
