Inquiry regarding removal of a 3mm black dot on the back of the hand and aftercare

I want to safely and effectively remove a black spot about 3 millimeters (3mm) in size located on the wrist area.
I would like to inquire about availability, information, and precautions.
Because the wrist is a very mobile area, scar management can be more important, so I want to approach it with caution.

1. What is the appropriate treatment method?
​ To minimize scarring in areas with a lot of movement like the wrist, do you remove a mole of this size all at once?
Or is it done in several stages (in parts)?
2. How long will it take?
3. Essential aftercare to minimize scarring on the wrist area:

I am curious about specific care methods to minimize scarring and prevent recurrence after mole removal.
Especially in areas with frequent movement such as the wrist, regenerative tape (such as Duoderm)
How many days should I wear it, and what precautions should I take in daily life, such as touching water?

Please tell me how to safely remove moles on my wrist and have clear skin.
