Are there any risks (besides laser plume, fire/electrical hazard, and those to skin and eyes) to the patient from the medication laser EQUIPMENT itself (like erbium, pulsed dye, fractional CO2, and hair removal), such as any harmful radiation or toxic substances? I'm not interested in a consultation with a physician close to home if it may be answered here. Thank you kindly.
There are many risks and possible complications from any procedure. It depends an on what is used for, the patient and how it is used. To answer your question correctly you need to have a consultation with a board certified or eligible physician close to your home.
Everythings have two sides of the coin and doctor have to study hard, well trained and choose the right treatment without complication to their patient and even to themselves.
