How do you keep track of your skincare routine?

Hello, I've been wanting to manage my skin more systematically lately, so I'm planning to start recording my home care routine, including skincare products like lotion, cleanser, and sheet masks. How do you keep track of your skincare routine? For the past few weeks, I've been trying to write down my daily experience after using cleanser, lotion, and sheet masks. As I've been using them consistently, I've been able to figure out which products work best for my skin. Has anyone else noticed any clearer changes or effects from keeping a skincare journal? Also, if you have any special tips for keeping a journal, could you share them? I'm curious about your tips for consistently managing your skin through a skincare journal!
