tanned back after Maldives vacation

Need help!!! i’ve had a terrible sun tan after my recent Maldives vacation. it does seem to have a lightened a little however it still seems pretty dark. my current routine for AM is using chemist at play mild exfoliating bodywash with AHA daily body lotion and spf and in the PM i just use a kojic acid moisturizer on a cleaned back. twice a week in the PM i am using my Foxtale AHA/BHA/PHA exfoliant and layering with a moisturizer.

i am afraid whether or not this may go away plus have a very very important family function in the last week of January and will be wearing a saree and i am worried this is going to look horrible with a blouse.

is there anything i can do for this? i have been to multiple vacations before but never have i tanned like this. hands, face and legs are tanned too but it doesn’t look absolutely uneven like my back does.

please help with anything you thing that might work or should i just go back to my dermat? looked up some chemical peel treatments for tan online that can be done as an in-clinic procedure with dermats but its super expensive plus i am not sure if it will really help.

please help! :(
