Stratum corneum function

The outermost epidermal layer of flattened, keratinized cells that limits water loss and blocks entry of microorganisms and chemicals; it is the main barrier targeted by moisturizers and exfoliants.

Transepidermal water loss

Movement of water from the dermis through the epidermis to the environment. Elevated TEWL indicates barrier impairment and is reduced by occlusives and ceramide-containing products.

Fitzpatrick phototype

A six-level classification of skin response to ultraviolet light based on burning and tanning history. It guides product selection and risk assessment for waxing, peels, and laser referral.

Comedogenic

Describes an ingredient or product with a tendency to clog follicles and promote comedones. Non-comedogenic products are preferred for acne-prone clients.

Salicylic acid

A beta-hydroxy acid that is lipid-soluble and penetrates follicles, making it useful for acne and oily skin. It is a common superficial peeling and exfoliating agent.

Glycolic acid

An alpha-hydroxy acid derived from sugar cane that exfoliates by loosening corneocyte cohesion. Concentration and pH determine strength, and neutralization or timed removal is required.

Skin analysis

Visual and tactile evaluation of skin type, condition, hydration, oiliness, and lesions during consultation. Findings determine product selection, treatment plan, and contraindications.

Manual extraction

Removal of non-inflamed comedones and pustules using gentle pressure with gloved fingers or a comedo extractor. Inflamed cysts and nodules are not extracted and are referred.

Effleurage

A light, gliding massage stroke applied in the direction of muscle fibers and lymphatic flow. It warms tissue, aids product absorption, and promotes relaxation.

High-frequency current

An alternating electrical current applied with a glass electrode that produces a mild germicidal and drying effect. It is used on acne-prone skin and requires intact skin.

Clay mask

A mask containing absorbent clays that draw excess oil and debris from the skin. It is suited to oily and congested skin and is removed before it fully dries.

Chemical peel depth

Determined by acid type, concentration, pH, and contact time. Superficial peels affect the epidermis; deeper effects require medical supervision outside esthetic scope.

Sanitize versus disinfect

Sanitizing reduces pathogens on surfaces through cleaning; disinfecting destroys most pathogens on nonporous items using an EPA-registered product with a specified contact time.

Hospital-grade disinfectant

An EPA-registered product labeled to kill a broad range of pathogens on nonporous implements. Implements must be clean and fully immersed for the label contact time.

Single-use items

Porous or difficult-to-clean items such as cotton, wooden sticks, sponges, and nail files that cannot be disinfected. They are discarded after one client.

Blood spill procedure

Wear gloves, absorb the spill with disposable material, clean the area, then disinfect with an EPA-registered tuberculocidal product for the full label contact time.

Esthetician scope Nevada

A Nevada esthetician license authorizes skin care, makeup, and hair removal by waxing or tweezing. Medical or invasive procedures are outside the license and prohibited.

Board inspection authority

The Nevada State Board of Cosmetology may inspect licensed establishments during business hours without prior notice to verify sanitation, licensing, and compliance with regulations.

Unlicensed practice

Performing licensed services for compensation without a current Nevada license. It is a violation subject to citation, fines, and disciplinary action.

License renewal

The periodic process of maintaining an active Nevada license by paying renewal fees and meeting continuing education requirements by the Board's deadline.

Keratinocyte migration

The movement of keratin-producing cells from the stratum basale to the stratum corneum, taking about 28 days in young adults and slowing with age.

Melanocytes

Cells in the stratum basale that produce melanin. Melanin determines skin color and provides some protection from ultraviolet radiation damage.

Sebaceous glands

Glands that secrete sebum into follicles, concentrated on the face, scalp, and upper trunk. Androgen influence and sebum output contribute to acne formation.

Eccrine sweat glands

Widespread glands that produce watery sweat to regulate body temperature. They are distinct from apocrine glands, which are limited to axillae and groin.

Dermis composition

The layer beneath the epidermis containing collagen and elastin fibers, blood vessels, nerves, glands, and hair follicles. It provides structural support and nourishment.

Hair growth cycle

The repeating anagen, catagen, and telogen phases of follicle activity. Waxing is most effective on anagen hair, which is actively growing and firmly anchored.

Hard wax

A wax applied warm and removed without cloth strips, suitable for sensitive areas and coarse hair. It shrinks around hair as it cools and is lifted against growth direction.

Waxing contraindications

Conditions that preclude waxing, including isotretinoin use, recent retinoids or peels on the area, active infection, sunburn, and open lesions.

Double-dipping

Reinserting a used applicator into the wax pot after contact with skin. It is prohibited because it contaminates the product; use a fresh applicator each time.

Color correction makeup

Use of complementary colors to neutralize unwanted tones: green cancels redness, peach or orange cancels blue and dark circles, and yellow corrects purple bruising.

Foundation shade matching

Selecting a foundation by testing along the jawline in natural light, matching both depth and undertone (warm, cool, neutral) to the client's skin.

Informed consent

Documented client agreement after being told the nature, risks, expected results, and aftercare of a service. It is obtained before treatment and recorded in the client file.
