TX Esthetician Exam Flashcards

Q: How many flashcards are in this set?

This set includes 50 original cards covering skin sciences, facials and massage, hair removal, chemical exfoliation, sanitation and infection control, implements and equipment, electricity and light therapy, product chemistry, client consultation, and Texas TDLR law.

Q: Who administers the Texas esthetician exam and what is required first?

TDLR licenses estheticians and contracts PSI to deliver both the written theory exam and the practical skills exam. You must first finish 750 hours of instruction at a TDLR-licensed school before applying to test.

Question 1

How many training hours does Texas require for a standalone esthetician license, and where must they be earned?

Accepted Answer

750 hours of instruction at a TDLR-licensed barbering/cosmetology school. The hours cannot all be completed online — hands-on practical instruction is required. A combination Manicurist/Esthetician or Hair Weaving Specialist/Esthetician course is 800 hours.

Question 2

Which agency licenses Texas estheticians, and which vendor delivers the exams?

Accepted Answer

The Texas Department of Licensing and Regulation (TDLR) regulates esthetician licensing through its Barbering and Cosmetology program. PSI is the contracted third-party vendor that administers both the written and practical exams.

Question 3

What two exams must a Texas esthetician candidate pass, and how are they scored?

Accepted Answer

A written theory exam and a separate hands-on practical skills exam. They are scored independently — you must pass both. Passing one does not carry over if you fail the other; only the failed part must be retaken.

Question 4

How often must a Texas esthetician renew, and what is the consequence of letting the license lapse?

Accepted Answer

Renew every 2 years. An expired license cannot legally be used to perform services. TDLR allows late renewal with added fees for a limited window; long lapses can require reapplication, so renew before the expiration date.

Question 5

What continuing education does TDLR require for esthetician renewal, and what subject is mandatory within it?

Accepted Answer

4 hours of TDLR-approved CE each 2-year cycle, of which at least 1 hour must cover sanitation. Recent rules also require human-trafficking prevention awareness training. CE keeps practitioners current on safety and infection-control standards.

Question 6

What is 'scope of practice' for a Texas esthetician, and why does it matter on the exam?

Accepted Answer

It defines services a license legally permits — skin care, facials, makeup, and hair removal of the face/body. It excludes acts like cutting living tissue, injectables, or laser procedures reserved for medical professionals. Working outside scope is a violation.

Question 7

Why may a Texas esthetician NOT remove skin tags, moles, or use a lancet to extract under the skin?

Accepted Answer

Cutting, puncturing, or removing living tissue is a medical act outside the esthetician scope. Estheticians work only on the surface — extractions must stay non-invasive. Diagnosing or treating skin disease is reserved for physicians.

Question 8

Distinguish a 'license' from a 'salon/establishment permit' under TDLR rules.

Accepted Answer

A personal license authorizes the individual to perform services. A separate salon (establishment) license/permit authorizes the physical location to operate. Both must be valid and posted; an establishment cannot run on a practitioner's license alone.

Question 9

What is the layered structure of the epidermis from deepest to most superficial?

Accepted Answer

Stratum basale (germinativum) -> stratum spinosum -> stratum granulosum -> stratum lucidum (thick skin only) -> stratum corneum. New cells form at the basale and shed at the corneum, taking roughly a month to migrate up.

Question 10

What is the difference between the dermis and the epidermis?

Accepted Answer

The epidermis is the outer, avascular barrier layer of dead and maturing keratinocytes. The dermis beneath it is living connective tissue holding blood vessels, nerves, hair follicles, sebaceous and sweat glands, collagen, and elastin.

Question 11

What roles do collagen and elastin play, and which 'damage' is associated with their breakdown?

Accepted Answer

Collagen gives skin firmness and strength; elastin gives it stretch and recoil. UV exposure, smoking, and aging degrade both, producing wrinkles and sagging. Protecting them is the rationale behind sun protection and antioxidant care.

Question 12

What does melanin do, and what produces it?

Accepted Answer

Melanin gives skin its color and absorbs UV to shield deeper cells from damage. It is produced by melanocytes in the stratum basale. Uneven melanin activity causes hyperpigmentation (excess) or hypopigmentation (loss).

Question 13

Define the acid mantle and the typical pH of healthy skin.

Accepted Answer

The acid mantle is a thin film of sebum and sweat on the skin surface, normally about pH 4.5-5.5 (slightly acidic). It inhibits bacteria and supports the barrier. Harsh, high-pH cleansers disrupt it and can trigger irritation.

Question 14

What is the difference between sebaceous glands and sudoriferous glands?

Accepted Answer

Sebaceous (oil) glands secrete sebum to lubricate skin and hair, usually opening into follicles. Sudoriferous (sweat) glands secrete sweat to cool the body and excrete waste. Overactive sebaceous glands contribute to oily skin and comedones.

Question 15

How do the Fitzpatrick skin types help an esthetician plan treatment?

Accepted Answer

The Fitzpatrick scale (I-VI) rates how skin responds to UV, from always-burns/never-tans (I) to deeply pigmented/rarely burns (VI). Higher types have greater risk of post-inflammatory hyperpigmentation, so peels, lasers, and waxing must be more cautious.

Question 16

Differentiate a primary skin lesion from a secondary skin lesion.

Accepted Answer

Primary lesions are the initial change — macules, papules, pustules, vesicles, nodules, tumors. Secondary lesions develop later from primary ones — crusts, scales, fissures, scars, ulcers. Recognizing them guides referral and contraindication decisions.

Question 17

Distinguish a comedone, a papule, and a pustule in acne.

Accepted Answer

A comedone is a clogged follicle: open (blackhead) or closed (whitehead). A papule is a small raised, inflamed bump with no visible pus. A pustule is an inflamed lesion containing visible pus. Grading them shapes the facial approach.

Question 18

What causes a blackhead to appear dark, and why is calling it 'trapped dirt' wrong?

Accepted Answer

An open comedone is dark because trapped sebum and keratin oxidize on contact with air, not because of dirt. Knowing this corrects client myths and explains why aggressive scrubbing does not 'clean out' the color.

Question 19

Differentiate rosacea from common acne for skin analysis.

Accepted Answer

Rosacea is chronic facial redness with flushing, visible capillaries, and sometimes papules/pustules, typically without comedones. Acne features comedones and is follicle-based. Rosacea clients need gentle, non-stimulating care and often medical referral.

Question 20

What is the difference between hyperpigmentation and a vascular condition like telangiectasia?

Accepted Answer

Hyperpigmentation is excess melanin (sun spots, melasma, post-inflammatory marks). Telangiectasia is dilated/visible capillaries (couperose skin). One is a pigment issue, the other vascular — they call for different products and cautions.

Question 21

Why must an esthetician recognize but not diagnose conditions such as skin cancer, herpes, or impetigo?

Accepted Answer

Estheticians identify abnormal or contagious signs to avoid harm and refer out, but diagnosing is a medical act. Active herpes (cold sore) and impetigo are contagious contraindications — service is postponed and the client referred to a physician.

Question 22

What is the standard order of steps in a basic European facial?

Accepted Answer

Cleanse -> analyze skin -> exfoliate -> steam/soften -> extractions -> massage -> treatment mask -> tone -> moisturize/SPF. The sequence preps the skin progressively; extractions follow softening so pores release more easily.

Question 23

Why is steam (or warm towels) applied before extractions?

Accepted Answer

Heat and moisture soften sebum and loosen follicle contents, easing extraction with less pressure and trauma. Steam also boosts circulation. Forcing extractions on un-softened skin causes bruising and broken capillaries.

Question 24

Name the five classic massage manipulations and their general purpose.

Accepted Answer

Effleurage (light gliding), petrissage (kneading), friction (deep rubbing/circular), tapotement (light tapping/percussion), and vibration. They relax muscles, increase circulation, and aid product absorption. Sessions usually begin and end with soothing effleurage.

Question 25

When is facial massage contraindicated?

Accepted Answer

Avoid massage over active acne pustules, open lesions, sunburn, severe rosacea, recent injectables/fillers, or undiagnosed lumps. Massage can spread bacteria, inflame conditions, or displace recent cosmetic work. When in doubt, refer or skip the step.

Question 26

What is the difference between mechanical and chemical exfoliation?

Accepted Answer

Mechanical exfoliation physically scrubs off dead cells (scrubs, brushing, microdermabrasion). Chemical exfoliation dissolves the bonds between cells using acids or enzymes. Mechanical is more abrasive; chemical can penetrate deeper and is selected by skin type and goal.

Question 27

Distinguish AHAs from BHAs and when each is preferred.

Accepted Answer

AHAs (glycolic, lactic) are water-soluble and work on the surface for dryness, dullness, and pigmentation. BHA (salicylic acid) is oil-soluble and penetrates into follicles, so it suits oily, acne-prone skin. Choosing the right acid matches the client's concern.

Question 28

Why must a client avoid certain medications and recent sun exposure before a chemical peel?

Accepted Answer

Retinoids, recent isotretinoin, and exfoliating actives thin the skin and raise burn risk; sunburned or freshly tanned skin is already compromised. Peeling over these can cause excessive irritation, hyperpigmentation, or scarring — hence pre-peel screening.

Question 29

Within an esthetician's scope, what depth of chemical peel is appropriate?

Accepted Answer

Estheticians perform only superficial (light) peels that affect the epidermis. Medium and deep peels reaching the dermis are medical procedures performed under physician supervision. Staying superficial keeps the service safe and within license limits.

Question 30

Why is patch testing and tracking peel timing important during a chemical exfoliation service?

Accepted Answer

A patch test screens for adverse reactions before full-face application. Timing the acid and neutralizing/removing it as directed prevents over-processing. Leaving a peel on too long can cause burns; following the product protocol protects the client.

Question 31

What is the difference between soft (strip) wax and hard (stripless) wax?

Accepted Answer

Soft wax is applied thin and removed with a fabric/paper strip; it grips fine hair and large areas. Hard wax is applied thick, hardens, and is pulled off without a strip; it is gentler for sensitive zones like the face, underarms, and bikini line.

Question 32

In which direction is wax applied and removed, and why?

Accepted Answer

Apply wax in the direction of hair growth and remove against the direction of growth, holding the skin taut. This pulls hair from the root cleanly and minimizes breakage, ingrowns, and bruising.

Question 33

Why must a wax applicator never be 'double-dipped' back into the pot?

Accepted Answer

Re-dipping a used stick contaminates the entire pot with bacteria from the client's skin, creating cross-infection risk. Each application uses a fresh stick (no double-dip). This is a core TDLR sanitation expectation tested on the exam.

Question 34

List key contraindications to waxing a client.

Accepted Answer

Avoid waxing over sunburn, active acne, eczema/psoriasis flares, open lesions, or skin on retinoids/recent chemical peels and isotretinoin. These areas can lift or tear when wax is removed. Diabetic and very thin skin needs extra caution.

Question 35

Differentiate the hair-growth phases anagen, catagen, and telogen.

Accepted Answer

Anagen is the active growth phase (hair is anchored and waxes best). Catagen is the brief transition phase. Telogen is the resting/shedding phase. Because hairs cycle, repeat sessions are needed to catch more follicles in anagen.

Question 36

What is the difference between cleaning, disinfecting, and sterilizing?

Accepted Answer

Cleaning removes visible debris with soap and water (always first). Disinfecting uses an EPA-registered product to kill most pathogens on hard, nonporous surfaces. Sterilizing destroys all microbial life. Salons disinfect; true sterilization (autoclave) is rare in esthetics.

Question 37

How must reusable, non-porous implements be disinfected between clients?

Accepted Answer

Clean off debris, then fully immerse in an EPA-registered, hospital-grade disinfectant for the full label contact time, and store in a clean, covered container. Implements must be disinfected (or single-use discarded) before touching another client.

Question 38

How are porous, single-use items handled differently from non-porous tools?

Accepted Answer

Porous/single-use items (wax sticks, cotton, gauze, sponges, paper) cannot be disinfected and must be discarded after one use. Only hard, non-porous implements can be cleaned and immersed in disinfectant for reuse.

Question 39

What is the proper response if a client is cut and bleeds during a service?

Accepted Answer

Stop the service, put on gloves, clean the wound, and apply an adhesive bandage. Disinfect any blood-contaminated surfaces/implements or discard single-use items, and place blood-soiled disposables in a sealed bag per bloodborne-pathogen rules.

Question 40

Differentiate a bactericidal from a virucidal and a fungicidal disinfectant claim.

Accepted Answer

Bactericidal kills bacteria, virucidal kills viruses, and fungicidal kills fungi. A salon disinfectant should carry the EPA registration and the claims needed for the pathogens of concern. Reading the label ensures the product is appropriate and used at correct dilution.

Question 41

Why is hand hygiene before and after every client a non-negotiable rule?

Accepted Answer

Hands are the leading route of cross-contamination. Washing (or using sanitizer) before and after each client breaks the chain of infection between the practitioner, the client, and tools. It protects both parties and is a standard TDLR sanitation requirement.

Question 42

What is a galvanic facial machine used for, and what are desincrustation vs. iontophoresis?

Accepted Answer

Galvanic current is a constant direct current. Desincrustation uses the negative pole with an alkaline solution to soften and emulsify sebum for deep cleansing. Iontophoresis uses polarity to push water-soluble product into the skin. Polarity choice drives the effect.

Question 43

What does high-frequency current do in a facial, and when is it avoided?

Accepted Answer

High-frequency (Tesla/violet ray) current produces a mild germicidal and warming effect, helping with acne and product penetration. Avoid on clients who are pregnant, have a pacemaker, epilepsy, or excessive metal implants/jewelry in the area.

Question 44

In LED light therapy, what are blue and red light generally used for?

Accepted Answer

Blue LED light targets acne-causing bacteria, while red LED light is used to support collagen and reduce the look of fine lines and redness. LED is non-thermal and non-invasive — a different tool from medical lasers, which are outside esthetician scope.

Question 45

Why must clients and the operator wear eye protection under a magnifying lamp, Wood's lamp, or LED?

Accepted Answer

Bright and UV/visible light sources can strain or damage the eyes. Eye pads or goggles shield the client; the operator avoids looking directly at intense light. A Wood's lamp (UV) is used in a dark room to reveal pigment and skin conditions.

Question 46

Define the four cosmetic-chemistry emulsion/ingredient roles: emollient, humectant, surfactant, and preservative.

Accepted Answer

Emollients soften and smooth (oils, esters). Humectants draw and hold water (glycerin, hyaluronic acid). Surfactants cleanse and emulsify (help oil and water mix). Preservatives prevent microbial growth so products stay safe. Together they form stable formulas.

Question 47

What is the difference between an oil-in-water and a water-in-water/serum product feel, and why does it matter for skin type?

Accepted Answer

Oil-in-water emulsions feel lighter and absorb fast, suiting oily/combination skin. Richer, oil-heavy creams suit dry skin. Matching the base to the client's oil/moisture balance prevents clogging oily skin or under-moisturizing dry skin.

Question 48

Why is sun protection (SPF) the cornerstone recommendation after exfoliation or peels?

Accepted Answer

Exfoliation removes the outer dead layer, leaving fresh skin more UV-sensitive. Without broad-spectrum SPF, clients risk burning and hyperpigmentation, which can undo the treatment. Daily SPF is the single most important anti-aging and pigment-prevention step.

Question 49

What belongs in a client consultation and intake before any service?

Accepted Answer

Review health/medication history, allergies, current skincare and actives (retinoids, recent peels), goals, and contraindications; perform a skin analysis; and document it. Consultation prevents adverse reactions and sets realistic expectations — it is the standard of care.

Question 50

Differentiate an absolute contraindication from a relative (precaution) contraindication.

Accepted Answer

An absolute contraindication means the service must not be performed (e.g., active herpes outbreak before a facial wax, contagious infection). A relative one means proceed with caution or modification (e.g., sensitive skin, minor irritation). Recognizing which applies protects the client.
