How are you managing your skincare routine?

These days, I've been keeping a daily journal of my cleanser, skincare routine, lotion, and sheet masks. Thanks to this, I've been able to gradually determine which products work best for my skin. How do you keep a journal of your skincare routine? Do you have any tips, like taking photos or writing down simple notes, to better see the results? I haven't made it a perfect habit yet, but I'm trying it because I think I'll see better results if I keep a journal. I'm also curious to know how others have experienced changes in their skin and the effectiveness of products through journaling. Lastly, if you have any tips for keeping a journal that you find most effective, please share them with us!
