Kate Somerville KateCeuticals Supercell Serum: The Spenny Bottle I Just Can’t Put Down
I’m the first to roll my eyes at “stem cell” skincare. Sounds like marketing fluff, right? Wrong. Kate Somerville KateCeuticals Supercell Rejuvenation Serum landed on my desk and refused to leave. I’ve been using it morning and night for three weeks. Here’s the evidence.

The Drop Test
One pump: silky, almost weightless, with a faint botanical scent. Absorbs in seconds, zero residue. First week I noticed my skin looked… rested. Like I’d slept 10 hours instead of 6.
The Visible Changes
The human stem cell conditioned media + growth factors aren’t cheap gimmicks, my skin looks legitimately younger. Not 10 years, but definitely a solid 3–5.
30ml feels tiny for the price, but two drops cover face + neck. It’ll last 2–3 months.
