Hydrogenated Polyisobutene is often used as a mineral oil replacement.

I can't comment on the matte black as I immediately lost interest, but not before I tried the metallic champagne on my lower lash line. I was so disappointed! Despite all the hype on TikTok, it just didn't work out for me—the product tugged, was hard to blend, and clumped around my eyelashes. I found the formula more chunky glittery and not the subtle, shimmery effect I hoped for.
