The area to be treated must be shaved at least 1 day before the hair removal session to prevent any burns. In fact, the hair is burnt by the laser, which can cause burns if it comes into contact with the skin. Apart from men’s beards, the face does not need to be shaved because the hair is downy. Above all, it is important to note that wax or tweezers must not be used to remove hair before the session because the bulb must remain intact to destroy it. Tanning must be avoided completely for at least 2 to 3 weeks and any photo-sensitizing treatments (e.g. antibiotics) before and after the session to prevent any skin burns. Applying suncream at least 1 to 2 weeks before the session is highly recommended.
