What are some ways to whiten skin after sunburn?

I am concerned about my facial skin becoming severely tanned and blotchy due to long overseas activities and frequent outdoor activities.

In particular, the cheekbones, forehead, and cheekbones are noticeably enlarged, making the overall skin tone look dull and dirty, making it difficult to look in the mirror.

I am curious about a treatment method that effectively removes pigmentation caused by UV exposure and restores the skin tone to its original clear and clean state.

I've been searching the internet for information on various skin lightening methods, but I'm having trouble deciding which procedure would be best for my skin type and pigmentation level.

My skin is slightly more dry than sensitive, and I tend to tan more easily than redden in the sun.

Given these characteristics, what specific medical procedures are recommended for skin whitening, simultaneously improving large areas of dark spots and brightening the overall complexion?

I think it would be icing on the cake if the treatment had a short recovery period (downtime) so I could quickly return to my daily life.

If I were to receive a treatment for recommended skin whitening, I would like to get advice on the approximate number of treatments, the interval between treatments, and home care methods to prevent recurrence of pigmentation after the treatment.

I would like to ask for professional advice on how to whiten skin with ampoules.
