Ive had the same experience. I had lots of whiteheads on my chin and mouth area from the virgin coconut oil- but I think Becca Bee is right- it was actually a detox symptom- as I used to use lots of chemical department store creams before resorting to all natural things. I turned my back on chemical products for my skin- and i think the Coconut oil pulled all the toxins to the first top layer of skin, causing the whiteheads to come out.
Now, I rub coconut oil all over my face after washing, and no longer have this problem. I am amazed at how soft my skin is- and I lovve the smell of the coconut oil on my skin!
