Precautions After Laser Treatment for Suddenly Darkened Melasma and Blemishes

As the weather gets warmer, the one that was hiding Dark spots and blemishes I feel like the scent is rising intensely again. Before it gets even stronger. Dark spots and blemishes I would like to get a laser treatment. Are there any special precautions I need to follow after the procedure? I exercise every day and sweat a lot, so I am wondering if it is okay to go to the gym on the day of the procedure or the next day. Also, Dark spots and blemishes I think I need to know in advance if scabs form after the treatment so that we can coordinate the schedule. All over the face. Dark spots and blemishes I'm upset because the tone looks dull, so I really want to tidy it up this time.
