Can you get laser treatment one day before you going to beach or after you come back from beach?

This is a good question. You will need to stay out of the sun (and indoor tanning beds) for the entire duration of your laser hair removal treatment, as sun exposure can lead to complications and hinder your final results. It’s also important that you don’t tan or use sunless tanning lotions right before your next appointment, as this can make it difficult for the laser to target the pigment in your hair. If you do need to spend time outdoors, make sure you cover up the treated area, hang out in the shade and wear plenty of sunscreen.

It's recommended to limit your sun exposure when undergoing laser hair removal, limiting tanning 2-4 weeks before and after treatments. Sun protection is essential. See an expert. Best, Dr. Emer

As a general rule we do not recommend sun exposure either immediately before or after laser treatments. It is best to wait at least two weeks in between exposure and treatment. You did not mention the kind of laser procedure you are interested having, but treating sun burned or deeply tanned skin with any laser is never a good idea. I hope that helps!
