I have oily skin and fully expected an oil based serum to break me out. I was only willing to try it because of how amazing everything else Honeybee Gardens is (like the Hydrogel and Aloe moisturizers being the only in the world to not break me out after decades of trying different moisturizers). So at first I would put on this oil based serum after washing face to let it sit like a mask to then wash it off. My skin felt pretty great afterward - like a dose of needed healthy oils. Then one night I fell asleep before washing it off and woke up to... no breakout. HOW?! I'm still too nervous to try this daily or with morning routine, but I do apply it occasionally as part of the nighttime routine (especially if I feel like I dried my face out too much with a cleanser) and it still hasn't broken me out - instead it's like some nice, healthy, get my face back to normal before I go so dry I get inflammation acne or ruin my skin barrier again. So even if you have oily skin and therefore avoid oil based serums, try this out - at least as a "rescue" for when you feel like you've gone too dry in your fight against your own oils.
