Getting rid of my forever face tan

I was never good at skincare, and growing up in 130 degree sunny weather with no sunscreen took a toll. Ever since I can remember my face has been tanned- the forehead in particular. Im south asian so uneven skin tone also exists around the mouth, but the forehead is very noticeable. I do wear sunscreen religiously now but the damage has been obviously done.

What products has worked for the brown girlies to get rid of the tan at home? Im a new mom with little time. I can be consistent with usage but would prefer something simple, like a single product that may not be perfect but will give results over time.
