Ingredient Library
The Vaiya Ingredient Library
Skincare labels are written in Latin and chemistry. Vaiya's ingredient guides help you understand what's actually in your products — what each ingredient does, who it helps, and who should be cautious — so you can read any label with confidence.
Instead of memorizing marketing buzzwords, you learn the small number of ingredients that actually do the work: the humectants and lipids that hydrate and protect, the actives that treat specific concerns, and the sunscreen filters that prevent damage in the first place. Every guide is written in plain English and cites its sources.
