Esthetician (South Korea National Technical Qualifications in Barbering and Beauty) study plan

Build a one-page reference table of the five pathogen groups (bacteria, viruses, fungi, parasites, biofilms) with at least two esthetics-relevant examples and the infection each causes.

Sequence the full implement workflow - pre-clean, wash, rinse, dry, disinfect, store - and record the EPA-registered hospital disinfectant contact time for at least three product types you actually stock.

Write and self-administer a 10-item matching drill that separates sanitation, disinfection, and sterilization, and score 90% or better.

Order the hand-washing and gloving steps into a numbered checklist of at least eight steps, then dry-run it three times while narrating each step aloud.

Compile a list of at least 12 client conditions or medications that require refusing, postponing, or modifying service, and write one sentence on the risk for each.

Audit a mock treatment room against a 25-item checklist and tag every item as sanitation-only, disinfection, or sterilization, correcting any mislabeled items.

Diagram a skin cross-section labeling the five epidermal strata, dermal papillary and reticular layers, hypodermis, and at least three cell types per layer.

Explain the acid mantle and barrier function in writing, including a stated surface pH value and what happens when the barrier is compromised.

Map infection-control rules onto three specific services (a basic facial, a lip-and-brow wax, a lash tint) and note the extra controls each one demands.

Describe the structure and function of sebaceous glands, sweat glands, hair follicles, and sensory nerve endings, and link each to a treatment decision.

Summarize the phases of wound healing and state which services must be avoided during each phase.

Classify at least 20 skin lesions as primary or secondary and mark which ones are contraindications to service versus referral-only findings.

Assess Fitzpatrick phototype, oiliness, hydration, and sensitivity on a volunteer and justify each rating with an observed cue.

Draft a 12-question intake script covering medications, allergies, pregnancy, recent waxing or peels, and prior reactions.

Sequence the standard steps of a professional facial from pre-service prep through post-service home-care recommendations, with a time allocation for each step.

Name the five classic massage movements (effleurage, petrissage, tapotement, vibration, friction), demonstrate each on a forearm, and list the contraindications specific to each.

Compare a 60-minute protocol for oily, acne-prone skin against one for dry, mature skin, and defend at least four product or technique differences.

Practice client draping, positioning, and pressure checks, then self-evaluate against a written ten-point comfort and modesty standard.

Classify exfoliants as physical, enzymatic, or chemical, and match at least six agents to the skin type and condition each suits.

Build a peel-depth decision tree covering superficial, medium, and deep peels, naming representative agents, typical concentrations, and pH ranges at each level.

List the peel contraindications that most often appear on exams, including isotretinoin use, pregnancy, recent waxing or shaving, active infection, and compromised barrier.

Write pre- and post-peel instruction sheets that state neutralization requirements where applicable and the signs of an adverse reaction requiring discontinuation.

Rehearse a client conversation declining a medium peel to a client who had waxed two days earlier, and script the alternative you would offer.

Explain the hair growth cycle, identify which phase waxing targets, and state why hair length and growth stage affect results.

Compare hard wax, soft wax, and sugaring on application temperature, technique, removal direction, and suitable body areas.

Write step-by-step waxing protocols for the lip, underarm, bikini, and leg, including patch testing, positioning, and post-care to reduce ingrown hairs.

Match foundation shades to at least five skin tones and apply color-theory corrections for redness, sallowness, and dark circles.

Outline patch-test and contraindication requirements for lash and brow tinting, lash lifts, and lash extensions, and state the manufacturer and licensing rules you must follow.

Differentiate galvanic, high-frequency, microdermabrasion, LED, ultrasound, and steam by mechanism, intended outcome, and typical session length.

List the indications, contraindications, and safety precautions for each device, including pregnancy, pacemakers, metal implants, and photosensitivity.

Demonstrate correct device setup and shutdown, then document the maintenance, cleaning, and cord-inspection routine for each unit.

Explain the difference between direct and indirect high-frequency application and state which one requires a gauze barrier.

Outline scope-of-practice boundaries, licensing and insurance requirements, informed consent, and client record retention for your jurisdiction.

Analyze four ethics scenarios - a client requesting an off-label peel, a coworker skipping disinfection, a social media before-and-after request, and a pricing conflict - and write the defensible response to each.

Resolve ten mixed practice questions drawn from all nine domains and log the rationale for every wrong answer.

Sit a full-length timed mock exam under exam conditions and review every missed item by domain to find your two weakest areas.
