The Gap
Where you actually live
41°C
Jaipur · Right Now
That's the gap. +19°C is why ingredients destabilize, why actives oxidize, and why most skincare doesn't work the way the box promised.
N° 01 · The First Formula
This one does.
Barrier Repair Serum. Formulated for 43°C. From the first molecule.
Stress-Tested
30ml / 1.0 fl.oz
Formulated for India
Five percent Niacinamide. Not ten, not twenty — because receptor saturation is the irritation it was supposed to prevent. Three percent thermal-stable Vitamin C, the kind that doesn't turn yellow at 43°C. Buffered to pH 5.5 to match your skin's acid mantle.

The Calibration
Calibrated. Not maxed.
The industry sells 10–20% concentrations. We chose 5% and 3%. Here's why that's not less — it's the science.
Why this exists
“I'm Indian. None of my skincare felt like it knew that.
That gap is the entire reason pHmatter exists.”
