Final answer:
Releasing the hold of a vacuum machine before lifting it off the skin can prevent skin irritation, marks and discomfort.
Step-by-step explanation:
By lifting your finger off the hold of a vacuum machine before lifting the device off the face, you can avoid causing unnecessary suction or pressure which might lead to skin irritation, temporary marks, or discomfort. A vacuum machine, when used for skin care treatments, creates a suction effect that helps to cleanse the pores, lift up the skin, and improve blood circulation. However, if not used properly, it can have adverse effects. Therefore, it is recommended to always release the hold of the machine before moving it away from the skin.
