The vacuum machine can do how many passes?

• A. Thyroid
• B. 3-5
• C. 2-3" x 4-6"
• D. Adding white to a color.

Answer: (B)

Using a vacuum machine in esthetics relies on performing several gentle passes over the treatment area. Moving the wand in smooth, overlapping strokes allows the suction to work progressively—lifting tissue, promoting circulation, and encouraging lymph drainage—without staying in one spot long enough to irritate the skin. This approach is safer and more effective than a single pass, giving consistent results while you monitor the skin’s response and adjust pressure as needed. The other options don’t fit because they refer to concepts outside this technique—anatomy not involved in the procedure, a measurement not related to how many passes are done, and color mixing—which aren’t about performing vacuum therapy.
