Equipment & Techniques Flashcards

What part of the PMU machine holds the needle?

Answer: Cartridge

In modern PMU machines, the needle is typically housed within a disposable cartridge. This cartridge securely holds the needle(s) and often includes a membrane to prevent pigment and bodily fluids from flowing back into the machine, ensuring hygiene and safety. The cartridge is designed for single-use and easy replacement.

What is the typical purpose of a round needle configuration?

Answer: Outlining and fine detail

Round needle configurations, especially smaller ones (e.g., 1RL, 3RL), are ideal for creating precise lines and fine details in permanent makeup. Their compact grouping allows for crisp outlines, hair strokes, and delicate work, making them suitable for procedures like eyeliner, lip lining, and microblading simulation.

What is the function of the power supply in a PMU machine?

Answer: Controls machine voltage

The power supply is a critical component of a PMU machine system. Its main function is to convert standard electrical current into the appropriate voltage and amperage needed to operate the handpiece. By adjusting the voltage, the technician can control the speed and power of the needle, which is essential for different techniques and skin types.

Which pigment base is best for clients with cool skin undertones?

Answer: Warm golden brown

For clients with cool skin undertones (e.g., blue, pink, red), it's generally recommended to use pigments with a warm base. A warm golden brown pigment will help to balance out the natural coolness in the skin, preventing the healed result from appearing too ashy, gray, or blue. This ensures a more natural and harmonious outcome.

What technique is used to implant pigment in small dots for a soft look?

Answer: Pointillism

Pointillism is a PMU technique where pigment is implanted into the skin using a series of tiny, individual dots. This method creates a soft, diffused, and natural-looking effect, often used for powdered brows or subtle lip blush. It differs from continuous lines or solid packing by building up color gradually through discrete points.

What is a common cause of pigment migration?

Answer: Incorrect depth

Pigment migration, often appearing as blurring or spreading of the pigment beyond the intended design, is commonly caused by implanting the pigment too deeply into the skin. When pigment is placed into the deeper layers of the dermis or even subcutaneous tissue, it can spread along tissue planes, leading to an undesirable 'blown out' effect.

What speed setting is typically best for sensitive or thin skin?

Answer: Low speed

For clients with sensitive or thin skin, using a low speed setting on the PMU machine is generally recommended. A lower speed reduces trauma to the delicate skin, minimizes discomfort, and allows for more controlled pigment implantation. This helps prevent excessive bleeding, swelling, and potential scarring, leading to better healing and pigment retention.

Why is stretching the skin important during application?

Answer: To allow precision and depth control

Stretching the skin taut during a PMU procedure is crucial for several reasons. It creates a smooth, firm surface for the needle to glide over, allowing for greater precision in pigment implantation. This tension also helps the technician maintain consistent depth control, preventing the needle from going too deep or too shallow, which is vital for optimal pigment retention and crisp lines.

What technique is best for a soft powder brow finish?

Answer: Powder brow technique

The powder brow technique uses a specialized machine to deposit pigment into the skin, creating a soft, diffused, and filled-in look similar to traditional brow powder. Unlike hair stroke methods or microblading which mimic individual hairs, this technique builds up color in a gradient, resulting in a gentle, airbrushed effect. This makes it ideal for clients seeking a subtle, makeup-like finish rather than crisp, defined strokes.
