About Corneo

Corneo is made by Selana Technologies LLC, a small company in Irvine, California. It was founded by Sean Chang.

Why it exists

Building a skincare routine usually means months of trial and error: which products, in what order, how often, and what should not go together. Most advice is one routine for everyone, and much of it is shaped by whoever has the biggest ad budget.

Corneo starts from what you already own. It checks each product against a short, written set of rules drawn from published dermatology guidance, holds back what should not mix, and suggests a product only for a step your shelf does not cover.

It also paces strong actives. A new retinoid or acid starts slowly and steps up only after you have actually logged the nights, so the routine follows your skin rather than the calendar. The rules are on How it works, and Corneo is not medical advice (see the Terms).
