A while ago I posted here another discussion which was a development of a skin cream. I ended up adopting it as a product but while it produces great results (the improvement in skin tone lasts several days) it has caused pimples on the back of my hands - and at my age I almost never break out. Opinions as to the probable cause will be welcome! I’ve posted the final formula below:
I’m not a professional, nor am I really a chemist, so take my comment with a grain of salt. I started making my own products, when the Art of shaving aftershave balm became too expensive for me. At first I used stearic acid as a thickener, but used to get acne after using it - even when I made a moisturizer with 8% glycolic acid, I still broke out when using steric acid as a thickener. I have extremely extremely oily Italian skin. When I removed that ingredient from my formula, the effect went away. That could just be my skin though. I don’t use stearic acid in any of the stuff I make anymore, except bar soap.
Thanks George. I have other creams with more than 2% stearic that don’t cause this problem, so I am inclined to think it must be either the Chia oil, or the Emulgin VL75 (this is the first time I have used that emulsifier) or maybe the cetearyl is too high. I think perhaps I’ll do a knockout on the Emulgin first.
