It will not clog pores (it actually helps to open them and keep them clean) and has no odor. I use it and love it. You only need a few small drops at a time and I works well for both oily and dry skin (balances sebum production).
It is actually supposed to help with acne. I have been using it for over 4 months and have seen a major improvement in my skin. I don't use BP anymore. I only use purpose to wash with and then jojoba oil (and my birth control pill) and my face is clear. If you do a search for it you will find lots of information about jojoba oil and the benefits it has on acne.
