Can chemical peels help remove a 2 year old tan from my hands caused by too much sun exposure?

For two years, my hands were directly exposed to sunlight while driving my scooter. The temperatures were more than 38 degrees and the UV index was very high and I remember that my hands used to burn. My arms are completely normal because I used to wear a sweat shirt but I did not wear gloves on my hands. Now, I have tanned hands which look completely abnormal if compared to my hands. I wear sunscreen everyday and I have tried a lot of other things but nothing has worked. Will chemical peel help?
