Question 1: What is the primary structural protein found in the epidermis that
provides strength and protection?
A. Keratin
B. Collagen
C. Elastin
D. Melanin
CORRECT ANSWER: A. Keratin
Rationale:Keratin is a fibrous structural protein that is the key component of the
epidermis, hair, and nails. It provides a protective barrier and structural integrity.
Collagen and elastin are primarily found in the dermis, while melanin is a pigment.
Question 2: Which layer of the skin is responsible for the production of new
skin cells through mitosis?
A. Stratum corneum
B. Stratum granulosum
C. Stratum basale
D. Stratum lucidum
CORRECT ANSWER: C. Stratum basale
Rationale:The stratum basale (germinativum) is the deepest layer of the epidermis
where active cell division (mitosis) occurs. New cells are pushed upwards to replace
shed skin cells from the surface.
Question 3: What is the primary function of melanin in the skin?
A. To produce vitamin D
B. To provide sensory perception
C. To protect against ultraviolet (UV) radiation
D. To regulate body temperature
CORRECT ANSWER: C. To protect against ultraviolet (UV) radiation
Rationale:Melanin is a pigment produced by melanocytes in the stratum basale. Its
primary function is to absorb and scatter UV radiation, thereby protecting the skin from
DNA damage and sunburn.
,Question 4: Which of the following skin types is characterized by a dull
appearance, roughness, and a tendency to flake?
A. Oily skin
B. Dry skin
C. Combination skin
D. Normal skin
CORRECT ANSWER: B. Dry skin
Rationale:Dry skin (xerosis) lacks adequate moisture and sebum, resulting in a tight,
rough, and dull appearance. It is prone to flaking and fine lines. Oily skin is characterized
by excess sebum, and combination skin has both oily and dry areas.
Question 5: What is the primary cause of open comedones (blackheads)?
A. Bacterial infection
B. Dead skin cells and oxidized sebum trapped in a hair follicle
C. Allergic reaction to cosmetics
D. Over-hydration of the skin
CORRECT ANSWER: B. Dead skin cells and oxidized sebum trapped in a hair
follicle
Rationale:A blackhead forms when a hair follicle becomes clogged with a combination
of sebum and dead skin cells. The dark color is not dirt but oxidized melanin and sebum
on the surface of the plug.
Question 6: What is the function of the acid mantle?
A. To attract moisture to the skin
B. To provide a protective, slightly acidic film that inhibits bacterial growth
C. To produce collagen and elastin
D. To increase the pH of the skin to alkaline levels
CORRECT ANSWER: B. To provide a protective, slightly acidic film that
inhibits bacterial growth
Rationale:The acid mantle is a fine, slightly acidic film on the skin's surface (pH ~4.5-
5.5) formed by a mix of sebum and sweat. It serves as a protective barrier against
bacteria, fungi, and environmental pollutants.
Question 7: Which muscle is responsible for the "smile" expression by drawing
the corners of the mouth upward?
A. Orbicularis oris
B. Zygomaticus major
C. Frontalis
D. Platysma
CORRECT ANSWER: B. Zygomaticus major
,Rationale:The zygomaticus major muscle originates at the cheekbone and inserts at the
corner of the mouth. Its contraction pulls the corners of the mouth upward and outward
to produce a smile.
Question 8: The skull is divided into two main parts: the cranium and the:
A. Mandible
B. Maxilla
C. Facial skeleton
D. Hyoid bone
CORRECT ANSWER: C. Facial skeleton
Rationale:The skull consists of the cranium, which encloses and protects the brain, and
the facial skeleton (or facial bones), which provides the structure for the face. The
mandible and maxilla are specific bones within the facial skeleton.
Question 9: What is the primary function of the sebaceous glands?
A. To produce sweat for cooling
B. To produce sebum to lubricate and waterproof the skin
C. To produce melanin for pigmentation
D. To produce keratin for hair growth
CORRECT ANSWER: B. To produce sebum to lubricate and waterproof the skin
Rationale:Sebaceous glands are attached to hair follicles and secrete an oily substance
called sebum. Sebum lubricates the skin and hair, prevents them from drying out, and
provides a degree of waterproofing.
Question 10: Which of the following is a common contraindication for a facial
treatment?
A. Dry skin
B. Oily skin
C. Active herpes simplex (cold sore)
D. Comedonal acne
CORRECT ANSWER: C. Active herpes simplex (cold sore)
Rationale:An active cold sore is a highly contagious viral infection. Performing a facial
treatment on an area with an active cold sore can spread the infection to other areas of
the client's face or to the therapist, making it a strict contraindication.
Question 11: What is the term for the surgical removal of wrinkles by
tightening the facial skin?
A. Dermabrasion
B. Chemical peel
C. Rhytidectomy
D. Blepharoplasty
, CORRECT ANSWER: C. Rhytidectomy
Rationale:A rhytidectomy, commonly known as a face-lift, is a surgical procedure that
removes excess facial skin, tightens underlying tissues, and re-drapes the skin on the
face and neck to reduce wrinkles and sagging.
Question 12: Which vitamin is essential for the synthesis of collagen in the
skin?
A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin K
CORRECT ANSWER: B. Vitamin C
Rationale:Vitamin C (ascorbic acid) is a crucial cofactor for the enzymes prolyl and
lysyl hydroxylase, which stabilize and cross-link collagen fibers. Without Vitamin C,
collagen production is impaired, leading to weak tissue integrity.
Question 13: The term "sebostasis" refers to:
A. Excessive sweating
B. Excessive production of sebum
C. A decrease or absence of sebum production
D. Inflammation of a sebaceous gland
CORRECT ANSWER: C. A decrease or absence of sebum production
Rationale:Sebostasis is the condition of reduced or absent sebum secretion, which is
often seen in aging skin or in people with conditions like atopic dermatitis. It leads to
xerosis (dry skin).
Question 14: Which of the following massage movements involves a circular,
kneading motion that lifts and squeezes the muscles?
A. Effleurage
B. Petrissage
C. Tapotement
D. Friction
CORRECT ANSWER: B. Petrissage
Rationale:Petrissage is a massage technique characterized by kneading, rolling, lifting,
and squeezing the soft tissues. It deeply penetrates muscles, improving circulation and
relaxation, and is more vigorous than effleurage.
Question 15: What is the name of the bone that forms the forehead?
A. Temporal bone
B. Occipital bone
