Final answer:
During a facial treatment, the recommended average distance for placing an infrared lamp is 30-35 cm to effectively penetrate the skin and maintain safety.
Step-by-step explanation:
The average distance an infrared lamp should be placed during a facial is typically between 30-35 cm. This distance ensures that the infrared light can penetrate the skin effectively without causing discomfort or potential harm due to heat exposure.
It is important to follow manufacturer instructions and professional guidelines to optimize the benefits of infrared light therapy while maintaining safety during a facial treatment.
The average distance an infrared lamp should be placed during a facial is approximately 10-15 cm (1). The distance is important to ensure that the heat and light produced by the lamp reach the face evenly and effectively. Placing the lamp too far away may result in insufficient warming and therapeutic effects, while placing it too close may cause discomfort or potential skin damage.
Therefore answer is 1) 10-15 cm.
