SMP Techniques & Tools 3 — Questions and Answers
Question 1: What is 'dot migration' in SMP and what primarily causes it?
- Pigment fading due to sun exposure
- Dots spreading beyond their original size due to excessive depth or large needle gauge (Correct answer)
- Color shifting from black to blue over time
- Loss of dots due to immune response
Correct answer: Dots spreading beyond their original size due to excessive depth or large needle gauge
Dot migration occurs when pigment is placed too deep or with too wide a needle, causing the dot to spread and blur.
Question 2: How should a practitioner adjust needle depth when working on thinner scalp skin, such as in the temporal region?
- Increase depth to ensure pigment retention
- Decrease depth to avoid placing pigment in subcutaneous tissue (Correct answer)
- Maintain standard depth regardless of skin thickness
- Switch to a magnum needle for wider coverage
Correct answer: Decrease depth to avoid placing pigment in subcutaneous tissue
Thinner temporal skin requires shallower needle depth to keep pigment in the dermal layer and prevent migration.
Question 3: Which motion technique is used when placing SMP dots to avoid dragging pigment across the skin?
- Circular sweep
- Whip shading
- Straight stippling (perpendicular insertion) (Correct answer)
- Feather stroke
Correct answer: Straight stippling (perpendicular insertion)
Perpendicular stippling — pressing straight down and lifting — creates clean, isolated dots without dragging pigment.
Question 4: What is the purpose of the 'test dot' method performed at the start of an SMP session?
- To check machine power output
- To assess how the client's skin accepts pigment before full application (Correct answer)
- To calibrate the autoclave temperature
- To determine ink mixing ratios
Correct answer: To assess how the client's skin accepts pigment before full application
Test dots placed in a discreet area reveal how the skin accepts and retains pigment before full coverage is applied.
Question 5: When creating an SMP hairline, which dot placement approach creates the most natural transition?
- Dense, evenly spaced dots at the front edge
- Irregular, sparse dots at the outer edge graduating to denser dots behind (Correct answer)
- Solid pigment line followed by dot work
- Horizontal rows of uniform dots
Correct answer: Irregular, sparse dots at the outer edge graduating to denser dots behind
Irregular, sparse dots at the hairline edge mimicking natural hair density variation create the most realistic appearance.
Question 6: Which needle speed setting (strokes per minute) is typically used for SMP to maintain controlled dot placement?
- 100–200 SPM
- 500–800 SPM
- 1,500–2,000 SPM (Correct answer)
- 3,500–4,500 SPM
Correct answer: 1,500–2,000 SPM
SMP practitioners typically use 1,500–2,000 SPM for controlled, precise dot placement without excessive skin trauma.
Question 7: What role does needle cartridge 'click depth' or adjustable grip depth play in SMP technique?
- It controls pigment viscosity during application
- It sets the length of needle exposure to regulate insertion depth (Correct answer)
- It determines the machine voltage output
- It locks the cartridge to prevent wobble
Correct answer: It sets the length of needle exposure to regulate insertion depth
Adjustable grip depth controls how far the needle protrudes, directly regulating the depth of pigment insertion.
