NJ Esthetician key terms

Use of a chemical product registered with the EPA to destroy most harmful microorganisms on hard, non-porous surfaces and implements. It is stronger than sanitation but does not reliably kill bacterial spores.

Routine cleaning and lowering of microorganism counts on surfaces, tools, and linens to a safe level. It is the minimum standard for items that contact intact skin and is performed before disinfection.

Process that destroys all microbial life, including bacterial spores, usually through steam autoclave or dry heat. In esthetics it applies to items that may contact broken skin or blood.

A product carrying an Environmental Protection Agency registration number and label claims for specific kill times. Estheticians must follow the label's contact time and dilution exactly to achieve disinfection.

The number of minutes an implement or surface must stay visibly wet with disinfectant to achieve the label's kill claim. Shortening contact time means the item is not considered disinfected.

Federal OSHA rule requiring employers to protect workers from blood and other potentially infectious materials through exposure control plans, hepatitis B vaccination offers, gloves, and labeled sharps containers.

Practice of treating all blood, body fluids, and non-intact skin as potentially infectious regardless of a client's known health status. Gloves and barriers are used for every client, every time.

Barriers worn to prevent contact with infectious material, such as disposable gloves, eye protection, and aprons. Gloves are changed between clients and never washed and reused.

A product or tool designed to be used on one client and then discarded, such as wooden spatulas, cotton strips, and disposable lancets. It must never be disinfected and reused.

The outermost epidermal layer of flattened, keratin-filled dead cells that forms the skin's main barrier against water loss and irritants. Its condition strongly affects how products penetrate and how skin looks.

The avascular outer layer of skin where cells are produced and pushed upward to keratinize. It contains no blood vessels, so it heals without scarring and receives nutrients by diffusion.

The deeper, vascular layer containing collagen, elastin, nerves, glands, and hair follicles. It supplies the epidermis with nutrients and is where wrinkles, scarring, and most sensory receptors originate.

A tough fibrous protein that fills skin, hair, and nail cells as they mature, creating a protective outer surface. In skin it forms the water-resistant barrier of the stratum corneum.

Pigment produced by melanocytes that gives skin, hair, and eyes their color and absorbs ultraviolet radiation. Uneven production shows up as freckles, melasma, or post-inflammatory hyperpigmentation.

Oil-producing gland attached to a hair follicle that secretes sebum to lubricate skin and hair. Overactivity contributes to oily skin, comedones, and acne breakouts.

Structural protein in the dermis that gives skin strength and support. Production declines with age and sun exposure, contributing to laxity and fine lines.

Passage of water from inside the body through the epidermis into the air. Elevated water loss signals a compromised barrier and is associated with dryness, sensitivity, and irritation.

The skin's ability to keep water in and irritants, allergens, and microbes out, maintained largely by the stratum corneum and its lipids. Compromised barrier function makes treatments riskier and skin more reactive.

A person's genetically based baseline classification, usually described as normal, dry, oily, or combination. It is distinguished from a skin condition, which is temporary and can be treated.

A temporary, changeable state of the skin such as dehydration, sensitivity, or oiliness caused by environment, products, or health. It guides product selection for the current appointment.

A condition or circumstance that makes a treatment unsafe or inadvisable, such as active infection, open lesions, or recent cosmetic surgery. Identifying it protects the client and limits liability.

A clogged pore formed when sebum and dead cells block a follicle. An open comedone is a blackhead; a closed comedone is a whitehead beneath the skin surface.

Darkening of skin at a site of injury or inflammation, more common in medium to deep skin tones. Aggressive extractions, waxing, and peels can worsen it if inflammation is not controlled.

Small controlled application of a product on a discreet area to check for an allergic or irritant reaction before full use. Results are read after the interval stated on the product label.

A molecule with water-loving and oil-loving ends that lets cleansers lift oil and debris from skin so it can be rinsed away. Harsh surfactants can strip the barrier and leave skin tight.

An ingredient such as glycerin or hyaluronic acid that attracts and holds water in the upper skin layers. It supports hydration but needs an occlusive to prevent water loss in dry environments.

An ingredient that forms a film on the skin surface to slow water loss, such as petrolatum or dimethicone. Occlusives are used after hydration to seal moisture into the barrier.

Removal of dead surface cells by mechanical scrubbing or chemical agents such as alpha hydroxy acids. Overuse damages the barrier and increases sensitivity, redness, and sun risk.

A six-point classification of skin tone based on how skin responds to ultraviolet exposure, from always burning to rarely burning. It guides waxing, laser, and peel decisions and sun-protection advice.

The active growth stage of the hair cycle, when the follicle is deepest and the hair is most firmly anchored. Waxing during this phase is more painful and more likely to break hairs.

The resting stage of the hair cycle, when the hair detaches from the follicle and sheds. Waxing is most effective when many hairs are in this phase because they release cleanly.

The repeating sequence of growth, transition, and rest that every follicle follows independently. Because follicles cycle out of sync, clients need repeated waxing appointments to catch hairs at the right stage.

A reason to postpone or avoid waxing, such as isotretinoin use, recent chemical peel, sunburn, active infection, or varicose veins in the area. Removing hair over compromised skin can tear it.

Reinserting a wax applicator that has touched a client's skin back into the wax pot. It contaminates the supply and is prohibited; single-use applicators or clean spatulas are required.

The study of how hues relate and neutralize one another, applied in makeup to correct discoloration. Opposite colors on the wheel cancel each other, such as green reducing redness.

Using a pigmented product to neutralize an unwanted undertone before foundation, such as peach for blue bruising or green for redness. Correctors are applied thinly and blended.

Selecting a base whose depth and undertone blend seamlessly with the client's face and neck in natural light. Testing on the jawline rather than the hand gives a truer match.

A service that curls natural lashes by applying a lifting solution to break and reform bonds, followed by a setting lotion. It requires a patch test and careful timing to avoid overprocessing.

Measuring brow start, arch, and tail points relative to the client's facial features before shaping. It creates symmetry and is documented in the consultation to set expectations.

A client's agreement to a service after being told its benefits, risks, alternatives, and aftercare in language they understand. It is documented in the record before the service begins.

The structured intake conversation covering goals, health history, medications, allergies, prior services, and home care. It identifies contraindications and forms the basis of the treatment plan.

The services and procedures an esthetician is legally trained and licensed to perform under state law. Working outside it, such as diagnosing disease, is prohibited.

The professional duty to keep client health information, records, and personal details private and share them only as required by law. It builds trust and is part of ethical practice.

The state board that licenses estheticians and shops and enforces the Cosmetology and Hairstyling Act through rules on sanitation, continuing education, and discipline. Candidates should know its licensing and inspection requirements.

Required hours of approved instruction a licensee completes during each renewal period to maintain an active license. New Jersey sets specific hour and topic requirements that must be documented.
