So basically i am doing a research where i am comparing a variable before and after. The problem is according to my data my variable before is normally distributed whereas the same variable after isn’t. So what descriptive statistic method should i use? And are they even comparable?

What do you want to compare? The means? The distributions? Quantiles? Higher-order Moments? Expectiles? …

Forget about what the distribution looks like. Focus on what you are interested in finding out *without regard to what the data happen to look like*.

Presumably you're dealing with paired data, so you'd be interested in demonstrating something about pair-differences -- e.g. a mean change (after-before difference), for example - focus on that information. If you particularly want to also  summarize the before and after values themselves, choose measures that relate to that difference of interest.
