How can I whiten my sunburned face?

I want to know how to make this family's face whiter.

One of my family members works in a job that exposes them to the sun.
I enjoy the work itself because I get to meet a lot of different types of people, and I'm doing a good job at my role.
Working outside under the sun every day has made my skin quite tanned and rough.
That's so hard...
Even if you wear a hat with a large brim and take good care of your sunscreen, there are limits.
Sometimes, I finish work around 2pm, but sometimes I have to leave early in the morning and finish late in the evening, so I'm watching with regret (you probably know what I'm doing, right??)
This is why my face can't be perfect. That's why I'm asking this question. Is there a way to make my face whiter while working consistently?
How to whiten your face, are there any ampoules, ointments, packs, etc.??
How can I get a whiter face without ampoules or something like that??
