Skin Science is 1 of 13 topics on the Texas Class A Barber written exam — part of fadejunkie's 299-question practice bank. Below are 15 real Skin Science questions with real answers.
A client in their teens keeps getting oilier by the week even though nothing about their routine changed. What's usually driving that?
Hormonal changes. Sebum output is largely hormone-driven, which is why oil levels spike hard during puberty and other hormonal shifts.
Why doesn't a light surface scrape of the epidermis draw blood?
The epidermis has no blood vessels of its own — those live in the dermis underneath it.
What's the name of the oily substance your sebaceous glands make that keeps skin lubricated and hair from drying out?
Sebum. Sebum is the natural oil sebaceous glands produce — it lubricates skin and keeps hair from turning brittle.
What's the main skin issue a basic moisturizing cream is formulated to fix?
Dryness. Moisturizers are built to address dryness — locking in and adding back water the skin has lost.
Which layer of the epidermis is the one you're actually touching when you touch someone's skin?
Stratum corneum. The stratum corneum is the outermost layer — dead, flattened cells that form the surface you're actually touching.
Besides genetics, what's the actual pigment responsible for the color of someone's skin?
Melanin. Melanin, produced by melanocytes, is the pigment that determines skin color — genetics just sets how much of it you make.
Which massage movement is a light gliding, stroking motion?
Effleurage.
Which of these exfoliation methods works by physically scrubbing dead skin away instead of dissolving it chemically?
Brushing. Brushing is mechanical exfoliation — physically buffing away dead skin cells — as opposed to chemical methods that dissolve the bonds holding them together.
A client wants an energizing scalp massage before a big event, not a relaxing one. Which movement delivers that stimulating effect?
Percussion. Percussion, or tapotement, uses light tapping strokes and is the most stimulating massage movement — effleurage is the gentlest.
Tapotement covers a range of percussion movements from light to hard. Which one is the lightest touch?
Tapping. Tapping is the softest tapotement movement — hacking is on the harder end of that same family.
Which massage movement boosts circulation and glandular activity?
Friction, a deep rubbing pressure applied over a fixed area, is the massage movement known for boosting circulation and glandular activity in the skin.
What is cataphoresis, in electrotherapy terms?
Using the positive electrode, the anode, to push an acidic product into the skin.
A client wants to soften the look of fine surface wrinkles from aging skin. Which treatment targets that?
Microdermabrasion. Microdermabrasion mechanically exfoliates the top layer of skin, which softens the look of fine surface wrinkles.
A skin care device uses an extremely low level of electrical current, well below what other galvanic treatments run. What's that treatment called?
Microcurrent. Microcurrent is specifically defined by that very low electrical current level, distinct from the stronger galvanic techniques.
Which skin treatment tool can actually help the body produce vitamin D, the same way sunlight does?
Ultraviolet lamps. UV exposure — whether from the sun or a UV lamp — triggers vitamin D production in the skin.
