AAM AAM Pigment Chemistry & Ingredient Knowledge 2 — Questions and Answers
Question 1: What is the purpose of a patch test before a micropigmentation procedure?
- To determine needle depth
- To check for allergic reactions to the pigment or anesthetic (Correct answer)
- To test the machine's calibration
- To assess skin hydration levels
Correct answer: To check for allergic reactions to the pigment or anesthetic
A patch test involves applying a small amount of pigment or topical anesthetic to the skin 24–48 hours before the procedure to identify potential allergic reactions.
Question 2: How does oxidation affect iron oxide-based micropigmentation pigments over time?
- It causes the pigment to turn blue
- It can shift warm pigments toward cooler or ashy tones (Correct answer)
- It dissolves the pigment entirely
- It darkens all shades permanently
Correct answer: It can shift warm pigments toward cooler or ashy tones
Oxidation of iron oxide pigments over time can shift warm brown tones toward gray, red, or ashy hues as the chemical composition changes.
Question 3: Which ingredient in a topical anesthetic is responsible for its numbing effect in micropigmentation?
- Lidocaine (Correct answer)
- Glycerin
- Benzalkonium chloride
- Propylene glycol
Correct answer: Lidocaine
Lidocaine is the active anesthetic agent in most topical numbing products used in micropigmentation, blocking sodium channels to inhibit nerve signal transmission.
Question 4: What is the significance of pigment particle size in micropigmentation?
- Larger particles heal faster
- Smaller particles carry higher migration and fading risk (Correct answer)
- Particle size determines color vibrancy only
- Only particle shape matters, not size
Correct answer: Smaller particles carry higher migration and fading risk
Smaller pigment particles are more susceptible to migration and phagocytosis by macrophages, leading to faster fading and potential spreading.
Question 5: What does the term 'pH balance' of a pigment affect in micropigmentation?
- The sterilization timeline
- Skin reaction, color stability, and healing outcome (Correct answer)
- Needle corrosion rate
- Machine motor speed
Correct answer: Skin reaction, color stability, and healing outcome
The pH of a micropigmentation pigment affects how the skin responds to it, influencing inflammation, color shift during healing, and long-term stability.
Question 6: Which of the following best describes an inorganic pigment in the context of micropigmentation?
- A pigment derived from plant sources
- A mineral-based pigment such as iron oxides (Correct answer)
- A synthetic dye with complex carbon chains
- A pigment that breaks down within 6 months
Correct answer: A mineral-based pigment such as iron oxides
Inorganic pigments are mineral-derived (such as iron oxides and titanium dioxide) and are generally more stable, less allergenic, and more predictable for dermal implantation.
