Do you use separate moisturizers for morning and evening?

These days, it seems like even moisturizers are divided into day and night types.
I just bought one and apply it in the morning and at night,
Do you all use them separately?
What is the difference between the day version and the night version?
Is the night version a slightly thicker formula, and the day version applies a bit more lightly?
I'm curious if there is a difference in the ingredients.
If it's better to use them separately, I'm thinking of buying two and sharing them.
