Chapter 477, Florida Statutes

The state law that governs the practice of cosmetology, including esthetics, in Florida. It sets licensing requirements, scope of practice, and grounds for discipline. The Department of Business and Professional Regulation enforces it.

Related: Florida Administrative Code Chapter 61G5, Scope of Practice
Florida Administrative Code Chapter 61G5

The rules adopted under Chapter 477 that fill in operational details: licensure procedures, sanitation standards, school requirements, and continuing education. Estheticians are held to these rules as well as the statute itself.

Related: Chapter 477, Florida Statutes, Continuing Education Requirement
Scope of Practice

The legally permitted range of services an esthetician may perform under a Florida facial specialist license, such as skin care treatments, hair removal by waxing, and makeup application. Performing services outside this boundary can lead to discipline.

Related: Facial Specialist License, Electrolysis
Facial Specialist License

The Florida credential authorizing a person to perform esthetic services limited to the face and neck, including cleansing, exfoliation, extraction, waxing, makeup, and lash and brow services. It is distinct from the full cosmetology license.

Related: Scope of Practice, Continuing Education Requirement
Continuing Education Requirement

The biennial training hours a Florida-licensed esthetician must complete to renew a license, including specified hours on sanitation and infection control and on state law and rules. Documentation must be kept and produced on audit.

Related: Florida Administrative Code Chapter 61G5, Sanitation
Electrolysis

Permanent hair removal using a fine probe and electric current to destroy the follicle. In Florida this is a separately licensed practice and is not within the facial specialist scope, so an esthetician may not offer it.

Related: Scope of Practice, Depilation
Sanitation

The routine reduction of microorganisms on tools, surfaces, and hands to a safe level using approved disinfectants, soap, and water. It is the minimum standard applied between every client and does not destroy all spores.

Related: Disinfection, Sterilization
Disinfection

The use of an EPA-registered hospital-grade product on nonporous implements and surfaces to destroy most pathogenic organisms, including some spores, after cleaning. Required for items such as tweezers and wax spatulas between clients.

Related: Sanitation, Sterilization, Hospital-Grade Disinfectant
Sterilization

The complete destruction of all microbial life, including bacterial spores, usually by autoclave, dry heat, or chemical vapor. It is a higher level than disinfection and is required for items that contact broken skin or blood.

Related: Disinfection, Autoclave
Autoclave

A device that sterilizes implements using pressurized steam at high temperature. Items must be cleaned first, pouched, and processed for the correct cycle; the unit needs regular spore testing to confirm it is working.

Related: Sterilization, Single-Use Item
Hospital-Grade Disinfectant

An EPA-registered product labeled as a hospital disinfectant, effective against a broad range of pathogens. It must be used at the label dilution and contact time, and kept in a labeled, covered container with implements fully submerged.

Related: Disinfection, Contact Time
Contact Time

The number of minutes an implement or surface must stay wet with disinfectant for the product to work as labeled. Cutting contact time short leaves organisms alive, so the label's stated time must be followed exactly.

Related: Hospital-Grade Disinfectant
Single-Use Item

A product or implement designed to be used on one client and then discarded, such as wooden spatulas, cotton swabs, lancets, and disposable gloves. It is never cleaned and reused, which prevents cross-contamination.

Related: Cross-Contamination, Autoclave
Cross-Contamination

The transfer of pathogens from one person, tool, or surface to another, often by hands, dirty linens, or shared product. Preventing it is the core purpose of sanitation, disinfection, and handwashing routines in the treatment room.

Related: Single-Use Item, Sanitation
Epidermis

The outermost, avascular layer of skin, made of stratified keratinocytes that continually renew from the basal layer. It provides the barrier against water loss, irritants, and microbes, and it is what most esthetic products target.

Related: Stratum Corneum, Keratinocyte
Dermis

The layer beneath the epidermis containing collagen, elastin, blood vessels, nerves, glands, and hair follicles. Its condition determines firmness, wrinkles, and scarring, and it is where waxing and extractions can cause injury.

Related: Epidermis, Sebaceous Gland
Stratum Corneum

The outermost sublayer of the epidermis, composed of flattened, dead keratin-filled cells and lipids. It controls water loss and absorption, and exfoliation removes cells from this layer to smooth and brighten the skin.

Related: Epidermis, Exfoliation
Keratinocyte

The main cell type of the epidermis, produced in the basal layer and pushed upward as it matures into a keratin-filled corneocyte. Its roughly 28-day journey is the basis of the skin's renewal cycle.

Related: Epidermis, Stratum Corneum
Sebaceous Gland

A gland usually attached to a hair follicle that secretes sebum onto the skin surface. Its activity level underlies oily and dry skin types and contributes to acne when the follicle becomes blocked.

Related: Dermis, Comedo
Melanocyte

A cell in the basal epidermis that produces melanin pigment and transfers it to surrounding keratinocytes. Melanin gives skin its color and protects against ultraviolet damage, and its response explains post-inflammatory hyperpigmentation.

Related: Post-Inflammatory Hyperpigmentation, Epidermis
Skin Type

The classification of skin by its inherent oil and water balance, commonly described as normal, dry, oily, or combination. It is distinguished from a skin condition, which is a temporary or treatable state such as dehydration or acne.

Related: Skin Condition, T-Zone
Skin Condition

A temporary or ongoing state of the skin that can change with environment, products, hormones, or health, such as dehydration, sensitivity, or acne. Analysis separates conditions from the underlying skin type to guide treatment choices.

Related: Skin Type, Contraindication
T-Zone

The central band of the face across the forehead, nose, and chin, where sebaceous glands are denser. It is commonly oilier than the cheeks, which is why combination skin shows oil in the T-zone and dryness elsewhere.

Related: Skin Type, Sebaceous Gland
Comedo

A blocked pore formed when sebum and dead cells plug a follicle. An open comedo is a blackhead darkened by oxidation; a closed comedo is a white bump beneath the skin surface and may develop into inflamed acne.

Related: Sebaceous Gland, Extraction
Extraction

The manual removal of comedones or milia from a pore using gentle pressure, usually after softening the skin with steam or a warm compress. Proper technique and hygiene reduce trauma, scarring, and infection risk.

Related: Comedo, Contraindication
Exfoliation

The removal of dead cells from the skin's surface, by physical scrubbing or by chemical agents such as alpha hydroxy acids. Overuse damages the barrier, so frequency and strength must match the client's skin.

Related: Stratum Corneum, Alpha Hydroxy Acid
Fitzpatrick Scale

A six-category scale describing skin color and its typical response to ultraviolet light, from very fair and always burning to deeply pigmented and rarely burning. It guides waxing, peeling, and laser-related risk assessment.

Related: Post-Inflammatory Hyperpigmentation, Skin Type
Depilation

Removal of hair at or just below the skin surface without removing the root, as with shaving or chemical depilatories. Regrowth appears quickly because the follicle remains intact.

Related: Epilation, Electrolysis
Epilation

Removal of hair from the root, as with waxing, sugaring, or tweezing, so regrowth is slower than with depilation. Waxing is the form most commonly performed within the esthetician's scope.

Related: Depilation, Waxing Contraindication
Waxing Contraindication

A condition that makes waxing unsafe, such as use of isotretinoin, recent chemical peel, sunburn, active infection, or thin fragile skin. Waxing these clients can tear skin, cause bleeding, or trigger hyperpigmentation.

Related: Epilation, Post-Inflammatory Hyperpigmentation
Patch Test

A small application of a product on a limited area, such as the inner arm or behind the ear, observed for a reaction before full use. It is standard practice for tinting and for clients with known sensitivities.

Related: Contraindication, Allergen
Patchy Eyebrow

An eyebrow with sparse or uneven hair growth, often shaped by filling gaps with powder or pencil. Sudden patchy loss can signal a medical condition and should be referred rather than simply camouflaged.

Related: Eyebrow Shaping
Eyebrow Shaping

Designing the brow by measuring proportions, then removing hair with tweezers or wax and filling with makeup. The arch and tail should follow the client's bone structure and be agreed on before hair is removed.

Related: Patchy Eyebrow
Lash Lift

A service that curls and lifts natural lashes using a chemical solution applied to a shield, with results lasting several weeks. A patch test and careful timing protect the eye area from irritation.

Related: Patch Test, Contraindication
Alpha Hydroxy Acid

A water-soluble acid such as glycolic or lactic acid that loosens the bonds holding dead cells, promoting exfoliation and smoother texture. It increases sun sensitivity, so daily sunscreen and client education are essential.

Related: Exfoliation, pH
pH

A scale from 0 to 14 measuring acidity or alkalinity, with 7 neutral and healthy skin near 4.5 to 5.5. Product pH affects how strongly acids act and how well the skin barrier is preserved.

Related: Alpha Hydroxy Acid, Stratum Corneum
Allergen

A substance that triggers an immune reaction such as redness, itching, or swelling in a sensitized person. Fragrances, preservatives, and some resins in wax are common culprits, so ingredient review and patch testing matter.

Related: Patch Test, Contraindication
Contraindication

Any condition, medication, or circumstance that makes a service unsafe or inadvisable for a client. Examples include active infection, open lesions, recent surgery, or pregnancy for certain treatments; identifying them protects both client and licensee.

Related: Waxing Contraindication, Patch Test
Post-Inflammatory Hyperpigmentation

Darkened skin left after injury or inflammation, such as a wax burn, harsh extraction, or picking. It is more common in darker skin tones and is best managed by preventing trauma and by consistent sun protection.
