Is there any risk or side affect of hair removal ?

With any medical procedure, there are certain risks involved. No matter how minimal the chances are you should understand the types of reactions could occur, the incident rate, and the procedures in place for handling adverse reactions.

Post Treatment Care

Some common instructions are:

Stay away from excess sun exposure and the tanning salons for at least 6 weeks after treatment. It may take more than one session to effectively make your body hair-free so be careful with your skin.
Make use of strong sunscreen lotion to protect your skin so that the recovery process is complete. Your doctor will prescribe a lotion unique to your skin and treatment used.
In case of redness or discomfort, apply cold ice packs to the area for relief. Make sure you have a good stock of them before treatment.

Agreed with @shizakhan. If you remove body hair by waxing, you should use pre and post waxing oils and lotions. These lotions will take care of almost everything. Just you need to be aware of the next waxing date. The gap between two waxing sessions should be at least 3-4 weeks.
