Anything I can do to get rid of tan?

I went on vacation for a week and on one of the days, I forgot to wear a waterproof sunscreen and ended up getting tanned since my sunscreen washed a bit in water as I was swimming and I wasn’t diligent with reapplying.

Is there anything I can do now to get rid of the tan or just wait for it to go away on its own. Moving forward, I am going to be more diligent with wearing sunscreen. It’s super cold here as a bonus so I am wearing several layers as well.
