So I picked up some sandalwood pre shave oil at AOS. I haven't had a pimple on my face since i was like fifteen years old, now that being said suddenly I have 2 monsters right under the chin..... This also correlates with me starting the use of a SR. So my question is could the cause of this break out simply be technique with the SR or has anyone else experienced a break out after using pre shave oils. And if so any suggestions for an alternative to the oil. Thanks in advance!
