Vegesil used alone feels nice if you are talking about just repackaging it as a finished good. I just don’t recall if it is preserved, so check the inci or deck on the sds. It should state it there. (or ask your rep) It’s not that complex to mimic the feel of. Many D5 replacements are nice, but not to be used pure as a serum. You’d end up craving the feel of something a little more viscous and loving as a face application experience (from a user perspective). …at that point if you are going to thicken raw materials like that, you might as well make it cost effective and just modify or make your own natural serum that feels just as nice. I suggest reading more about natural lipids that are compatible with silicones. It will inspire your creativity and allow you to explore on your own.
