Jojoba oil is my nemesis. I used to have normal, non-sensitive skin. But after trying lotions and serums that contained jojoba oil, I had the WORST breakouts in my life. Cystic pimples and milia, all over my cheeks, around my mouth and forehead. It took a while to figure out that what caused my breakout was jojoba oil, but I had to make couple trips to dermatologists to get rid of horrible breakouts, and it took me months to get rid of acne scars. It turned my skin into acne-prone, sensitive. I used to wear any products without any problems but now I've got sensitive skin, I have to choose makeups/skincare very carefully.
Can be comedogenic for some, but is overall an effective, soothing ingredient.
