What is the primary function of the stratum corneum?
Stimulating sebum production
Producing melanocytes for pigmentation
Generating new skin cells
Acting as a barrier to protect underlying tissues
The stratum corneum is the outermost layer of the epidermis and serves as the main barrier to infection, dehydration, and chemical exposure. It consists of dead, flattened cells rich in keratin and lipids. Maintaining its integrity is crucial for skin health and prevention of transepidermal water loss.
Which vitamin is essential for collagen synthesis in the skin?
Vitamin E
Vitamin D
Vitamin C
Vitamin A
Vitamin C is a cofactor for the enzymes prolyl and lysyl hydroxylase, which are essential for stabilizing and cross-linking collagen molecules. A deficiency in vitamin C can lead to impaired wound healing and weakened connective tissue. Many skincare formulations include ascorbic acid to boost collagen production.
Which type of ultraviolet radiation is primarily responsible for tanning and aging?
UVB
UVA
UVC
All types equally
UVA rays penetrate deeper into the skin, contributing to photoaging and indirect DNA damage through reactive oxygen species. UVB rays mainly affect the superficial epidermis and cause sunburn and direct DNA damage. UVC is largely absorbed by the ozone layer and does not reach the skin.
How often should disposable gloves be changed during a typical facial treatment?
Only if integrity is compromised
Between each client and after contamination
Only after applying masks
Once per day
Disposable gloves must be changed after each client or when they become torn or contaminated to prevent cross-contamination of pathogens. This practice is required by state board sanitation rules and OSHA standards. Reusing gloves can spread infection and compromise client safety.
Which of the following is a contraindication for waxing services?
Recent use of glycolic acid peel
Use of light moisturizer
Mild dryness
Oily skin type
Chemical peels containing glycolic acid thin the stratum corneum and make skin sensitive; waxing afterward can lead to tearing or irritation. A waiting period of at least two weeks after a chemical peel is recommended before waxing. Always review client's recent treatments to avoid adverse reactions.
The Fitzpatrick Scale is used to classify which skin characteristic?
Skin phototype and UV reaction
Skin moisture content
Skin elasticity
Sebum production levels
The Fitzpatrick Scale categorizes skin based on its response to ultraviolet light and propensity to tan or burn. It ranges from Type I (very fair) to Type VI (deeply pigmented). It's widely used to guide treatment settings and sun protection advice.
What does pH measure in skincare products?
Acidity or alkalinity
Viscosity
Moisture level
Osmotic pressure
The pH scale indicates the hydrogen ion concentration in a product, measuring how acidic or alkaline it is. Skin's natural pH is slightly acidic (around 4.5 - 5.5), which helps protect the barrier function. Skincare products formulated within this range help maintain skin health and microbiome balance.
What is the normal pH range of healthy skin?
3.0 to 4.0
7.0 to 8.0
4.5 to 5.5
6.5 to 7.5
Healthy skin maintains an acidic mantle with a pH between 4.5 and 5.5, which deters pathogens and preserves barrier function. Deviations can lead to dryness, irritation, or overgrowth of harmful bacteria. Many cleansers and toners are formulated to restore this natural acidity.
Which of the following is a mechanical exfoliant?
Benzoyl peroxide
Alpha hydroxy acid
Enzyme peel
Microdermabrasion crystals
Mechanical exfoliants physically abrade dead skin cells through friction. Microdermabrasion crystals or diamond tips gently polish the stratum corneum. Chemical exfoliants like AHAs dissolve cellular bonds rather than physically removing cells.
What is the medical term for freckles?
Nevus
Ephelides
Melasma
Lentigines
Freckles, or ephelides, are small, flat, brownish spots on sun-exposed skin caused by localized melanin production. They often increase with UV exposure and lighten in winter. Lentigines are similar but persist year-round.
What is the term for excessive oil production in the skin?
Seborrhea
Lymphostasis
Hyperkeratosis
Xerosis
Seborrhea refers to an overproduction of sebum by the sebaceous glands, leading to oily skin and potential clogging of pores. It can contribute to acne and a greasy complexion. Treatments often include oil-regulating cleansers and exfoliants.
Which essential oil is commonly used to soothe inflammation and redness?
Peppermint oil
Tea tree oil
Chamomile oil
Eucalyptus oil
Chamomile oil contains bisabolol and apigenin, compounds known for anti-inflammatory and calming properties. It helps reduce redness and irritation in sensitive skin. Always perform a patch test to rule out allergies.
Which color of LED light is most effective for treating acne-causing bacteria?
Green light (525 nm)
Blue light (415 nm)
Red light (630 nm)
Yellow light (590 nm)
Blue LED light around 415 nm wavelength targets and destroys Propionibacterium acnes bacteria by producing reactive oxygen species. It reduces inflammation and prevents new lesions. Red light is more for anti-aging and collagen stimulation.
Which type of mask is most appropriate for oily or acne-prone skin?
Cream mask
Clay mask
Sheet mask
Gel mask
Clay masks absorb excess oil and impurities from the skin through natural minerals like kaolin or bentonite. They help reduce shine, refine pores, and calm mild breakouts. Cream and gel masks are more hydrating and suited for dry skin types.
What is another name for open comedones?
Papules
Blackheads
Pustules
Whiteheads
Open comedones, commonly called blackheads, form when a follicle is clogged with sebum and dead skin cells but remains open at the surface, allowing oxidation to darken the plug. Closed comedones are called whiteheads. Proper exfoliation and deep cleansing help prevent their formation.
Which device uses warm steam to open pores during a facial?
Facial steamer
High-frequency wand
Microcurrent device
LED panel
A facial steamer emits warm, humidified air that helps soften keratin and open the pores, facilitating extractions and improving product penetration. It also boosts circulation and hydration. Steam should be used carefully to avoid overheating or irritating the skin.
What is the primary benefit of a lymphatic drainage facial massage?
Increasing melanin synthesis
Reducing fluid retention and puffiness
Stimulating sebum production
Exfoliating dead skin cells
Lymphatic drainage massage uses gentle pressure to encourage movement of lymphatic fluid, reducing edema and puffiness. It can also improve detoxification and skin tone. The technique supports the immune system and relaxation.
Galvanic current in esthetics is most commonly used for which treatment?
Ultrasonic scrubbing
Electrolysis hair removal
Desincrustation to soften sebum
LED phototherapy
Galvanic current applied in desincrustation uses a negative polarity to saponify sebum and debris in pores, making extraction easier. It is not the same as electrolysis, which uses a needle and direct current for hair removal. Desincrustation is a standard step in deep-cleansing facials.
Which androgen hormone is most associated with stimulating sebaceous gland activity in acne?
Progesterone
Estrogen
Dihydrotestosterone (DHT)
Cortisol
DHT, a potent derivative of testosterone, binds to androgen receptors on sebaceous glands, increasing sebum production and contributing to acne formation. Blocking DHT activity can reduce oiliness and breakouts. Hormonal treatments often target this pathway.
Melanocytes are located in which layer of the epidermis?
Stratum lucidum
Stratum corneum
Stratum granulosum
Basal layer (stratum germinativum)
Melanocytes reside in the stratum basale, where they produce melanin and transfer it to keratinocytes, giving skin its pigment. This positioning protects deeper cells from UV damage. Disorders of melanocytes lead to pigmentation disorders.
Tinea versicolor is caused by overgrowth of which organism?
Staphylococcus aureus (bacteria)
Dermatophyte fungi
Herpes simplex virus
Malassezia furfur (yeast)
Tinea versicolor is a superficial yeast infection caused by Malassezia species, resulting in hypopigmented or hyperpigmented patches on the trunk. It thrives in warm, humid environments. Antifungal shampoos or topical agents are standard treatments.
Which sunscreen ingredient provides broad-spectrum protection and is a chemical filter?
Avobenzone
Zinc oxide
Iron oxide
Titanium dioxide
Avobenzone absorbs UVA rays and is classified as a chemical filter. Zinc oxide and titanium dioxide are physical blockers that scatter UV radiation. Broad-spectrum products often combine chemical and physical filters.
Which ingredient is commonly used to lighten hyperpigmentation by inhibiting tyrosinase?
Ceramide
Salicylic acid

High-frequency electrotherapy is contraindicated during pregnancy due to safety concerns for fetal development. Other contraindications include epilepsy, pacemakers, and open lesions. Always review client medical history.
In radiation terminology, what is teletherapy?
Internal radioactive implant
Topical radioactive cream
External beam radiation treatment
Oral radiopharmaceutical
Teletherapy refers to external beam radiation therapy where a machine directs radiation at a tumor from outside the body. Brachytherapy involves internal radioactive implants. Estheticians must avoid treating clients currently receiving radiation therapy to prevent burns and complications.
What does TEWL stand for in skincare science?
Topical Enzymatic Water Lysis
Total Epidermal Wound Level
Transdermal Electrolyte Wash Level
Transepidermal Water Loss
Transepidermal Water Loss measures the amount of water that passes from inside a body through the epidermal layer to the surrounding atmosphere. It's a key indicator of the skin barrier's integrity. Products that strengthen the barrier reduce TEWL.
Which exfoliant uses enzymes to break down keratin?
Lactic acid
Glycolic acid
Salicylic acid
Papain from papaya
Papain is a proteolytic enzyme derived from papaya that digests the keratin protein in dead skin cells, promoting gentle exfoliation. It's suitable for sensitive skin. Chemical exfoliants like AHAs and BHAs work by acidifying cellular bonds, not enzymatic breakdown.
Which type of surfactant is considered mild and often used in low-irritation cleansers?
Anionic surfactant
Cationic surfactant
Nonionic surfactant
Amphoteric surfactant
Nonionic surfactants do not carry a charge and are generally milder on the skin, making them common in sensitive-skin cleansers. Anionic and cationic surfactants are stronger detergents and can be more drying or irritating. Amphoteric surfactants are intermediate in strength.
Which topical retinoid is available by prescription for treating acne and photoaging?
Retinyl acetate
Retinol
Retinyl palmitate
Tretinoin
Tretinoin is a prescription-strength retinoic acid that normalizes keratinization, reduces comedones, and stimulates collagen synthesis. Over-the-counter retinol and retinyl esters are less potent and require conversion in the skin. Clients often experience initial irritation and flaking with tretinoin.
What characterizes keloid scar formation in the dermis?
Excess collagen deposition extending beyond wound edges
Loss of collagen with sunken appearance
Formation of only epidermal scar tissue
Localized hyperpigmentation only
Keloids are overgrowths of fibroblastic tissue with dense, disorganized collagen extending beyond the original wound boundaries. They can be itchy or painful and often recur after excision. Treatment may include intralesional steroids or silicone sheets.
At what depth does a medium TCA peel typically penetrate?
Stratum basale only
Reticular dermis
Subcutaneous layer
Papillary dermis
A 20 - 35% TCA peel reaches the papillary dermis, inducing controlled coagulation and exfoliation of both epidermis and superficial dermis. This depth improves fine wrinkles and pigmentation. Deeper peels require more downtime and carry greater risk.
Sonophoresis enhances product penetration by using which principle?
Thermal heat induction
Acoustic cavitation to disrupt the stratum corneum
Magnetic fields to open pores
Electrical ion migration
Sonophoresis uses ultrasound waves to create microscopic cavitation bubbles that temporarily disrupt lipid bilayers in the stratum corneum, enhancing transdermal delivery of active ingredients. It's a non-invasive method that improves absorption. Parameters must be controlled to avoid tissue damage.
Which dermal layer is composed of loose connective tissue and houses capillaries and sensory nerves?
Basement membrane
Subcutaneous tissue
Papillary dermis
Stratum spinosum
The papillary dermis is the uppermost layer of the dermis, containing thin collagen fibers, capillary loops, and sensory nerve endings. It interlocks with the epidermis for nutrient exchange and sensation. Below it lies the thicker reticular dermis.
Diathermy in esthetic treatments primarily uses which type of current?
High-frequency alternating current
Direct galvanic current
Constant DC current
Low-frequency microcurrent
Diathermy uses high-frequency alternating current to generate deep heat within tissues, improving circulation and promoting relaxation. It differs from galvanic current, which uses direct current for iontophoresis. Proper training is required to avoid burns.
Which plant extract, known for its mucilage content, is used in soothing masks and wraps?

Blue LED light therapy works by producing what active compound in bacteria?
Keratin
Melanin
Nitric oxide
Reactive oxygen species (ROS)
Blue LED light excites porphyrins within Propionibacterium acnes, resulting in formation of reactive oxygen species that kill the bacteria. This non-invasive method reduces inflammation and acne lesions. It does not penetrate deeply and is best for superficial treatments.
Why should estheticians check a client's BUN and creatinine levels before a detoxifying body wrap?
To measure hydration status only
To assess liver metabolism
To ensure healthy kidney function for toxin elimination
To evaluate muscle enzyme levels
Blood urea nitrogen (BUN) and creatinine are indicators of renal function. Detoxifying wraps claim to draw toxins via lymph and blood; compromised kidneys may not eliminate these effectively. Checking labs can prevent undue strain on clients with renal impairment. NCBI on Renal Function Tests
Which of the following is a contraindication for full-body massage?
Dry skin
Eczema
Deep vein thrombosis
Mild sunburn
Deep vein thrombosis (DVT) poses a risk that massage pressure could dislodge a clot, causing embolism. Active infections, fever, and severe varicose veins are also contraindications. Always obtain medical clearance for high-risk conditions.
What type of molecular structure does glycerin have that makes it a humectant?
Long fatty acid chain
Silicone backbone
Ringed aromatic structure
Three hydroxyl groups able to bind water molecules
Glycerin is a triol with three hydroxyl groups that attract and hold water molecules, drawing moisture into the stratum corneum. This makes it a highly effective humectant in moisturizers and serums. It also improves skin barrier function.
Cysteamine topical agents are primarily used to treat which skin condition?
Acne vulgaris
Rosacea
Hyperpigmentation and melasma
Psoriasis
Cysteamine inhibits tyrosinase and thiochrome formation, reducing melanin synthesis in hyperpigmented conditions like melasma. It offers an alternative to hydroquinone with fewer irritant effects. It must be used under professional guidance.
Why is isopropyl alcohol used in autoclave steam sterilization preparation?
To cool instruments quickly
To act as a final sterilant
To lubricate autoclave parts
To remove oils and debris before steam sterilization
Cleaning instruments with isopropyl alcohol removes organic material, oils, and debris that could shield microbes from steam. Proper cleaning is essential before autoclaving to achieve effective sterilization. Alcohol alone is not sufficient for sterilization.
How does photodynamic therapy (PDT) with aminolevulinic acid (ALA) selectively target abnormal cells?
ALA is converted to protoporphyrin IX in abnormal cells, which produces ROS when activated by light
ALA dehydrates cells and causes thermal damage under infrared light
ALA binds DNA directly, inducing cell death under UV light
ALA acts as a photosensitizer only in healthy melanocytes
Aminolevulinic acid is preferentially taken up by rapidly proliferating or dysplastic cells and metabolized to protoporphyrin IX. Upon activation by specific wavelengths of light, protoporphyrin IX generates reactive oxygen species that destroy the targeted cells. This selectivity makes PDT effective for actinic keratoses and superficial skin cancers.
What role do copper peptides play in wound healing and skin remodeling?
They act as direct antimicrobial agents
They inhibit melanocyte activity
They stimulate fibroblast proliferation and collagen synthesis via growth factor activation
They exfoliate the stratum corneum enzymatically
Copper peptides (GHK-Cu) bind to receptors on fibroblasts, enhancing the production of collagen and glycosaminoglycans and accelerating wound repair. They also have antioxidant and anti-inflammatory properties. Their multifunctional nature supports skin regeneration.
Carboxytherapy for cellulite reduction involves infusion of carbon dioxide. What is its proposed mechanism?
CO? blocks adrenergic receptors in adipocytes
CO? induces local vasodilation, improves circulation, and enhances lipolysis
CO? causes neuromuscular blockade in fat cells
CO? directly dissolves adipose tissue upon contact
Injected CO? causes temporary vasodilation and microcirculation improvement, which can enhance oxygenation and metabolic waste removal. It may also stimulate lipolytic enzymes and collagen remodeling. Clinical studies show moderate improvement in cellulite appearance.
Fractional lasers create microthermal zones in the skin. What is the primary healing mechanism triggered?
Selective photothermolysis of hair follicles
Complete epidermal ablation with no collagen effect
Controlled dermal injury stimulates neocollagenesis and epidermal regeneration
Thermal coagulation of subcutaneous fat only
Fractional lasers deliver microscopic columns of thermal injury surrounded by intact tissue, promoting rapid reepithelialization and stimulating fibroblasts to produce new collagen. This fractional approach reduces downtime while improving texture and wrinkles. Parameters can be adjusted for ablative or non-ablative effects.
When examining a histology slide for basal cell carcinoma margins, which feature is most indicative of tumor invasion?
Thickened stratum corneum only
Increased melanocyte density along the basal layer
Subcorneal pustules filled with neutrophils
Nests of basaloid cells with peripheral palisading extending beyond the dermal-epidermal junction
Basal cell carcinoma is characterized by nests of small, hyperchromatic basaloid cells with peripheral palisading and clefting artifact, invading the dermis. Identifying these nests at margin edges confirms incomplete excision. Melanocyte changes indicate melanoma, not BCC.

Cheat Sheet
- Skin Anatomy & Physiology -
Review the three primary skin layers - epidermis, dermis, and subcutaneous tissue - and memorize the "Come Let's Get Sun Burned" mnemonic for the epidermal strata (Corneum, Lucidum, Granulosum, Spinosum, Basale) (American Academy of Dermatology). Understanding cellular turnover rates guides treatment intervals on your esthetician practice exam. Remember that collagen and elastin fibers in the dermis give skin its strength and resilience.
- Safety & Sanitation Protocols -
Differentiate sanitation, disinfection, and sterilization using the "Some Days Shine" trick - Sanitize, Disinfect, Sterilize - based on CDC guidelines (Centers for Disease Control and Prevention, 2020). Proper tool preparation and MSDS knowledge are critical to prevent cross-contamination in your esthetician state board practice test scenarios. Always record and review each product's safety data sheet before use.
- Facial Treatment Steps -
Master the five-step facial sequence: Cleanse, Analyze, Steam, Extract, Mask - remember it as "Clean And Steam Extractions Make Magic" (International Dermal Institute). Know contraindications such as active acne or rosacea before extraction. Test your timing skills by practicing 7 - 10 minutes of steam at 105°F for optimal pore softening.
- Chemical Exfoliation & pH Balance -
Understand that pH = −log[H❺] and that most AHAs work best at pH 3 - 4 (Journal of Cosmetic Science). Compare glycolic acid (small molecule for deeper penetration) versus salicylic acid (oil-soluble for oily skin) to choose the right peel. Recall "pH Pop" to remember that lower pH equals stronger acid action.
- Client Consultation & Documentation -
Use the SOAP method - Subjective, Objective, Assessment, Plan - to streamline consultations and document health history (National Board of Esthetics). Spot contraindications like eczema or recent laser treatments to ensure client safety on the esthetician exam practice test. Clear notes and effective communication boost client trust and exam confidence.
