Just thought I would share this as I was surprised to see how much it helped me. I ran out of moisturizer and decided to try using an oil blend. After some research online I mixed about 30 ml of grapeseed oil (available in some grocery stores or organic food stores) with about 4 drops of lavender essential oil and 2 drops of bergamot essential oil (available at most pharmacies). I applied it to my face, chest and back every morning (shake before using). It does feel greasy on the face but if you have to apply make-up you could blot after 15 min or so to get rid of the excess. Anyway, I was surprised to notice that after a few days my existing blackheads seemed to dry up completely or were greatly loosened, and there have been no new breakouts of acne in general. I'm in my mid-30s and have had acne all my life so find this quite remarkable & hope it helps someone else.
