This column on lash growth serums was planned for last month, but I had to delay it because a major TikTok craze caused my planned product picks to sell out. Lash growth serums aren’t new. But the way they’re made is changing. Old-school versions mostly use the lipid prostaglandin, which has hormone-like effects. This essentially helps lashes grow for longer, artificially delaying their shedding cycle. Because these hung on to lashes way beyond their natural residency, it was not unusual to end up with the lash equivalent of needing a bloody good haircut. Ends were gnarly, a bit chewed looking, like slept-in falsies after a big night.
The newer peptide-based serums assist the natural growth process, conditioning lashes and providing silky, strengthened quality for only a fraction less quantity. And they’re much gentler.
