In which direction should vacuum suction strokes be directed?

The correct answer indicates that vacuum suction strokes should be directed towards the nearest lymph node. This technique is important in facial treatments as it helps facilitate lymphatic drainage. By directing suction towards the lymph nodes, you can effectively promote the removal of toxins and excess fluid from the facial tissues. This method enhances circulation and aids in the overall detoxification process, which is beneficial for skin health and appearance.

When considering the other options, moving away from the lymph nodes could hinder the natural drainage process, whereas a circular motion may not effectively target the lymphatic system specifically. Additionally, downward strokes may not address the necessary connection to the lymphatic system and could lead to less effective results in fluid drainage. Directing the suction towards lymph nodes maximizes the treatment's efficacy in maintaining skin health.
