Straight answers to the questions people actually ask about skincare

Each page opens with a two-sentence answer, then explains the reasoning, the exceptions, and what to do next. Cosmetic guidance only — nothing here diagnoses or treats any condition.

Building a routine

Order, timing, and how few products you can get away with.

What order do I apply my skincare products in?

Limits & safety

Where cosmetic guidance stops and a clinician starts.

When should I see a dermatologist instead of using a skincare app?
