NY Esthetician key terms

A process using EPA-registered chemical products to destroy most harmful microorganisms on nonporous surfaces and implements, though not bacterial spores. New York requires it for reusable tools that contact skin.

The complete destruction of all microbial life, including bacterial spores, typically achieved with an autoclave using high-pressure steam. It is reserved for implements that penetrate skin or contact blood.

The first cleaning step, in which soap, water, and friction physically remove visible dirt, oil, and many microorganisms from surfaces and tools before disinfection or sterilization.

An infection-control approach in which all blood and body fluids are treated as potentially infectious, so barriers such as gloves are used with every client and every cleanup.

A standardized manufacturer document listing a product's hazards, safe handling, first-aid measures, and storage requirements. Salons must keep these sheets accessible for the chemicals they use.

Microorganisms such as hepatitis B and HIV that spread through contact with infected blood or body fluids, making gloves, sharps care, and handwashing essential in the salon.

Barrier items such as disposable gloves, aprons, masks, and eye protection worn to prevent contact with blood, body fluids, and chemicals during services and cleaning.

The transfer of microorganisms from one person, surface, or object to another, often through shared implements, unwashed hands, or fingers dipped into a product container.

The outermost, blood-vessel-free layer of the skin, made of layered epithelial cells. Its surface cells continually shed and renew, forming the body's primary barrier against water loss and infection.

The middle skin layer, containing collagen, elastin, blood vessels, nerves, glands, and follicles. It nourishes the epidermis and gives skin its strength, thickness, and elasticity.

The outermost epidermal layer of flattened, keratinized dead cells. It limits water loss, absorbs some topical ingredients, and largely determines how smooth and hydrated skin appears.

The pigment made by melanocytes in the epidermis that colors skin, hair, and eyes and helps shield cell nuclei from ultraviolet radiation. Amounts and distribution differ among individuals and ethnicities.

A gland usually connected to a hair follicle that releases sebum onto the skin surface. Overactivity contributes to oily skin and acne; underactivity contributes to dryness and flaking.

An oily secretion of the sebaceous glands that lubricates skin and hair, helps hold in moisture, and contributes to the skin's protective acid film. Excess is associated with congestion and acne.

The slightly acidic surface film formed by sebum, sweat, and cellular debris. It discourages harmful bacteria and supports barrier function, and harsh cleansers can temporarily disrupt it.

The primary structural protein of the dermis, arranged in fibers that give skin firmness and support. Sun exposure and aging reduce production, leading to lines and laxity.

A dermal protein that lets skin stretch and return to shape. Damage from ultraviolet light and aging reduces its function, contributing to sagging and crepey texture.

A pocket in the skin from which a hair grows, extending from the epidermis down into the dermis. It is the structure targeted by waxing and other root-level hair removal.

A six-category classification of skin based on how it burns and tans in sunlight. Estheticians use it to estimate sun sensitivity and choose safe treatment intensity.

The genetically based, relatively stable category describing a client's baseline skin behavior, usually normal, dry, oily, or combination. It guides routine product selection rather than short-term treatment decisions.

A changeable skin state such as dehydration, acne, sensitivity, or hyperpigmentation that may improve or worsen. Conditions are identified during analysis and can alter which services are appropriate.

Any health condition, medication, or circumstance that makes a service unsafe or inadvisable. Recognizing one during consultation protects the client and reduces the esthetician's professional liability.

A structured pre-service conversation in which the esthetician reviews the client's history, goals, and skin findings, explains the proposed plan, and confirms consent to proceed.

A document completed before service that records health history, medications, allergies, past treatments, and skin concerns. It supports safe choices and becomes part of the client's record.

Manual removal of comedones and pustules using gloved fingers or a comedone extractor after the skin has been cleansed and softened. Poor technique can bruise skin, spread bacteria, or cause scarring.

Removal of dead surface cells by mechanical methods such as scrubs or by chemical methods such as acids and enzymes. It smooths texture and improves product penetration but can over-sensitize skin.

A deep-pore cleansing technique that applies galvanic current with a conductive solution to soften sebum and loosen debris, usually preparing congested skin for extraction.

A direct electrical current used in facials for desincrustation or to push water-soluble products into the skin. Correct intensity and client screening prevent burns and shock.

Smooth, gliding massage strokes applied with light to medium pressure. They open and close a facial massage and spread product evenly over the skin.

A kneading, lifting, and squeezing massage movement that relaxes tissue and stimulates circulation. It follows effleurage and is avoided over inflamed, broken, or heavily congested skin.

Temporary hair removal in which warm wax is applied in the direction of hair growth and removed against it, pulling hair from the follicle along with dead surface cells.

A stripless wax that firms around the hair as it cools and is lifted off without cloth. It is often chosen for sensitive areas and for coarse or short hair.

A thin-applied wax removed with a cloth strip pressed over it. It suits finer, longer hair and larger areas, but can be more irritating to sensitive skin.

Removal of hair below the skin surface, including the root, as in waxing, tweezing, and threading. Hair takes longer to regrow than with surface-only methods.

A small trial application of a wax or product on a limited area to detect an allergic or irritant reaction before the full service. Results are checked after a waiting period.

The specific services and procedures an esthetician may legally perform under state law. Exceeding it can bring license discipline, fines, and personal liability.

A signed document confirming the client understands a service's risks, benefits, and alternatives and agrees to proceed. It documents informed permission and supports the esthetician's records.

The New York State credential issued to qualified estheticians after required training hours and a passing state exam. It must be posted and renewed as required.

A policy covering claims that a service caused injury or property damage. Many salons and landlords require estheticians to show proof of coverage.
