I am looking for a way to thicken an oily serum. I want to have a clear product, honey-like consistency or a bit lighter (I am thinking at the serums form Paula's Choice). I've tried cera bellina and different emulsifiers, but , of course, the result is somewhat opaque.
Is there something that you would suggest? And something that I could buy in the EU for personal use, as I do not own a company and I can't ask for samples from various suppliers?
