Section 1: Skin Anatomy and Physiology (Questions 1–40)
1. What layer of skin is the target depth for permanent makeup pigment
implantation?
A. Stratum corneum
B. Epidermis (upper layer)
C. Dermis (papillary layer)
D. Hypodermis (subcutaneous layer)
Correct Answer: C
Rationale: PMU pigment must be implanted into the papillary dermis (upper
dermis) at approximately 1.0–1.5mm depth. This ensures color retention and
proper healing. Too shallow (epidermis) results in poor retention; too deep
(reticular dermis/hypodermis) causes scarring and pigment migration.
2. How many layers does the epidermis contain?
A. 3 layers
B. 5 layers
C. 7 layers
D. 2 layers
Correct Answer: B
Rationale: The epidermis consists of five distinct layers from deepest to
superficial: stratum basale, stratum spinosum, stratum granulosum, stratum
lucidum (only in thick skin), and stratum corneum.
3. Which skin type has the thickest stratum corneum?
A. Facial skin
B. Palms and soles
C. Eyelid skin
,D. Neck skin
Correct Answer: B
Rationale: The palms and soles have the thickest stratum corneum to withstand
friction and pressure. This is important when considering pigment penetration
depth and needle selection for different body areas.
4. What is the primary function of melanin in the skin?
A. Hydration
B. Protection from UV radiation
C. Temperature regulation
D. Vitamin D production
Correct Answer: B
Rationale: Melanin produced by melanocytes provides natural UV protection.
Understanding melanin distribution helps PMU technicians assess undertones and
select appropriate pigment colors for different skin types.
5. The healing process for PMU typically involves which phases?
A. Inflammation only
B. Proliferation only
C. Inflammation, proliferation, and remodeling
D. Remodeling only
Correct Answer: C
Rationale: Wound healing occurs in three overlapping phases: inflammation (days
1–5), proliferation (days 4–21), and remodeling (weeks 3–24+). PMU technicians
must educate clients about expected healing timelines and aftercare for each phase.
6. What is the clear protective layer of the skin found on palms of hands and soles
of feet?
A. Stratum corneum
B. Stratum lucidum
C. Stratum granulosum
D. Stratum basale
Correct Answer: B
Rationale: The stratum lucidum is the clear protective layer of the skin found on
the palms of hands and soles of feet.
,7. How many major layers does the human body have in its skin?
A. 2
B. 3
C. 4
D. 5
Correct Answer: B
Rationale: The skin has three major layers: the epidermis, the dermis, and the
hypodermis (subcutaneous layer).
8. In what layer of the dermis do PMU artists tattoo?
A. Reticular layer
B. Papillary layer
C. Stratum basale
D. Hypodermis
Correct Answer: B
Rationale: PMU artists tattoo in the papillary layer (the "sweet spot") of the dermis,
which is the upper layer of the dermis.
9. What are the two types of melanin?
A. Eumelanin and Pheomelanin
B. Melanin and Keratin
C. Collagen and Elastin
D. Sebum and Sweat
Correct Answer: A
Rationale: The two types of melanin are Eumelanin (brown to black) and
Pheomelanin (yellow to red).
10. What is the hard protein found in the epidermis for hair and nails called?
A. Collagen
B. Elastin
C. Keratin
D. Melanin
Correct Answer: C
Rationale: Keratin is a protein that helps form hair, nails, and is found in the outer
epidermis layer.
, 11. What is the term describing tiny vessels under the skin forming a pattern?
A. Erythema
B. Mottled skin
C. Ecchymosis
D. Petechiae
Correct Answer: B
Rationale: Mottled skin is the term describing tiny vessels under the skin forming a
pattern.
12. What is the shedding of skin called?
A. Desquamation
B. Exfoliation
C. Keratinization
D. Melanogenesis
Correct Answer: A
Rationale: The shedding of skin is called desquamation.
13. What is the thinnest dermis thickness?
A. 0.3 mm on eyelids
B. 1.0 mm on cheeks
C. 2.0 mm on forehead
D. 3.0 mm on back
Correct Answer: A
Rationale: The dermis is thinnest at 0.3 mm on the eyelids and thickest at 3.0 mm
on the back.
14. What is the primary function of the stratum corneum?
A. Pigment production
B. Barrier protection
C. Sensory perception
D. Temperature regulation
Correct Answer: B
Rationale: The stratum corneum is the outermost layer of the epidermis and serves
as the primary barrier against environmental damage, pathogens, and water loss.
15. What type of skin cells produce melanin?
