How do you all schedule your exfoliation?

I'm writing this post because I'm always confused about how often I should exfoliate. I worry that exfoliating too often might thin my skin, but if I skip it, my makeup feels like it cakes, so I'm conflicted. Lately, I've been doing it lightly about once a week, but I'm not sure if that's the right amount. On days when my skin is particularly sensitive, I feel like it might be better to skip it altogether. They say it's best to adjust based on your skin condition, but it's hard to set a standard. I'm curious to know how everyone else sets up their exfoliation routines!
