Which area should never be treated with lasers due to sensitivity and risk of injury?

The correct choice is the periorbital region. This area, which includes the skin around the eyes, is particularly sensitive and poses a greater risk of injury when treated with lasers. The skin in the periorbital region is thinner than in other areas, making it more prone to potential damage from laser treatments. Additionally, the eyes themselves are a critical organ and are more vulnerable to adverse effects from laser light exposure. Treatment in this area requires additional caution due to the proximity of delicate structures, like the eyelids and the eyeball, which can lead to complications such as burns, scarring, or even permanent vision impairment if not done with extreme care or proper protective measures.

When considering other areas like the forehead, jawline, or neck, while they do have their sensitivities and risks, they do not carry the same level of risk associated with potential injury as the periorbital region does. Therefore, it is crucial for practitioners to avoid treating the periorbital area with lasers unless specifically trained and equipped to handle such delicate procedures with the utmost safety protocols in place.
