Finally figured out which serum actually works for me

I went a little crazy this past month and tried 3 different serums not at the same time 😅. Normally I just kind of guess whether something’s working, but this time I started using an app to take daily pics and jot down what I was using. Day to day my skin honestly looked the same in the mirror, and I kept thinking nothing’s changing.But when I looked back through the photos side by side, I could actually see the difference. One serum was quietly helping with texture and breakouts, one was a total dud, and one just irritated me more than anything.

It was such a satisfactory moment because without tracking I probably would’ve lumped them all together and given up. Now I feel like I can actually tell what’s worth keeping in my routine instead of just guessing.

Curious do you guys track your progress in any way or just go by feel?
