That part about a "small win" keeping you going is so real. I have had those clients where you try everything and nothing works, and you start doubting your whole approach. Sticking it out and finally finding what clicks for them, that is the best feeling. It is not just about clearing skin, it is about proving to yourself you can figure it out. Those little victories are what make the hard parts of this job worth it, right? What was the turning point that made the custom peel work?
Honestly I think I just got lucky and stopped overthinking it. My big brain moment was basically throwing my fancy plans out and going back to basics like a total noob, which is kind of hilarious.
