I had no breakout but some here did. Everyone's different and you really don't know how your skin reacts until you use it. Also not all oils are bad for the skin. Some oils are acutally helpful in clearing the skin up, reducing blemishes, scars, blackheaRAB and what not. One reason is oil dissolves oils. It can dissolve the excess sebum/dirt produced by the skin and in the process loosen blackheaRAB, clogged pores etc. That's why cleansing oil is so popular now and I actually found it cleanses better than a regular gel or foaming cleanser.
Even if you have a breakout it will most likely be temporary. Weigh the pros and cons. For myself I rather have an initial breakout than getting stuck with pitted scars for the rest of my life.
