Why Stella
Skin changes. Most people only see fragments.
Alice founded Stella to give more people a simple way to see their skin over time—alongside routines, life stages and the wider context around it.
A dermatologist sees your skin in a clinic once in a while. Stella sees it every few days, at home.
