I would like to ask about precautions after laser hair removal.

I am considering laser hair removal because I think it would be a good idea to start taking care of my skin in advance before summer comes. Since I do self-hair removal, I keep getting ingrown hairs and my skin seems to be discolored, so I plan to get a professional treatment before it's too late.

Since I have to make appointments regularly, I am writing this post to ask how often I should space out laser hair removal treatments. It seems like many people get the 5- or 10-session packages.

Also, since my skin is slightly sensitive, I would appreciate it if you could answer whether I need to shave beforehand on the day of the laser hair removal procedure, and whether there will be any issues with daily activities such as showering or exercising after the procedure.
