The science

Every active, at its right dose.

No headline active used in trace amounts just to look good on the label. Here's exactly what we put in our formulas, at what concentration, and what it does for your skin.

How to read

How to read an ingredient panel

On every product page, you'll find this table. On the left, the active. On the right, its actual concentration in the formula. That's our signature, and it's also your guarantee: what's written is what's working.

A concentration isn't a marketing claim — it's a number. Too low, the active does nothing. Too high, it irritates. Good formulation means finding the right point, and then publishing it.
