This is easily the most powerful oil I've ever used, not only for a cold (when clearing up the nostrils) and also believe it or not it works as acne treatment too. The bottle size however being very little, concludes the fact that it doesnt last very long. However in saying that, the cheapness of the bottle is also very rewarding. When using this as an acne remover (why I use it) I found that the best result come about when applying the lotion after a hot shower, when the face is still moist. A negative side is that the lotion does tend to burn a fair bit, when leaves me with a somewhat red complexion. However, ultimatly this works as a rapid acne remover, and possibly the most powerful one at that. When you add up all the advantages and disadvantages with this product, you'll understand why I recommend it.
