Esthetician Scope of Practice

The Governing Principle: Epidermis vs. Dermis

Every scope-of-practice question on the Texas esthetician exam reduces to one idea: estheticians work on the epidermis, not the dermis.

• The epidermis is the outermost, non-living layer of skin made mostly of dead, keratinized cells.
• The dermis is the deeper, living layer containing blood vessels, nerves, and collagen.

A service is within an esthetician's scope when it enhances or beautifies the epidermis by removing dead cells but does NOT pierce the dermis (living tissue). The moment a procedure invades living tissue, it becomes a medical act regulated by the Texas Medical Board, not TDLR.

Why it matters for the exam: memorize the phrase "does not pierce the dermis." If a question describes a treatment that reaches living tissue, draws blood, or injects substances, the answer is almost always "outside esthetician scope / requires a physician."

Services Estheticians MAY Perform

Under TDLR rules, a licensed esthetician is authorized to perform a defined set of skin-care services:

• Cleansing and beautifying treatments of the skin (classic facials).
• Facial massage and the use of facial equipment such as steamers, brush machines, galvanic current, high-frequency, vacuum, and a Wood's lamp for skin analysis.
• Body hair removal using depilatories, wax, chemicals, tweezers, or similar devices.
• Application of makeup, including color theory, eyebrow shaping, and semipermanent single-fiber eyelash extensions / artificial lashes.
• Superficial (light) chemical peels that exfoliate only dead epidermal cells.
• Limited microdermabrasion that removes only dead surface cells.

Conditional Services (Allowed Only If Non-Invasive)

Two services live on the boundary and are tested heavily:

1. Superficial / light chemical peels — permitted because they are non-invasive and non-aggressive, removing dead cells from the epidermis. A peel becomes prohibited the instant it reaches the dermis.
2. Microdermabrasion — permitted only "to the extent the device and technique removes only dead skin cells from the outermost layer (epidermis) and does not pierce the dermal layer." Deeper microdermabrasion that contacts living tissue must be delegated by a physician.

Services OUTSIDE Esthetician Scope

The following are medical procedures and are NOT within an esthetician's license. Performing them can trigger discipline and is the classic "wrong service" exam scenario:

• Medium and deep chemical peels that penetrate the dermis (living tissue).
• Deeper microdermabrasion that contacts or penetrates the dermis.
• Botox and dermal filler injections (must be ordered and delegated by a licensed physician).
• Dermaplaning — NOT within the esthetician scope in Texas. Per TDLR's "Who Regulates What?" guidance, non-scalpel-razor dermaplaning (dermablading with a razor that is not a medical scalpel) is a TDLR-regulated service that requires a Class A Barber license, not an esthetician license; only dermaplaning performed with a medical scalpel is regulated by the Texas Medical Board. Either way, it falls outside an esthetician's license.
• Laser hair removal and medical laser/IPL skin procedures beyond the cosmetic license.
• Any service that pierces, cuts, or injects into living tissue, diagnoses disease, or prescribes medication.

Quick Scope Reference Table

Establishment and Medical-Spa Rules

Scope applies to the business as well as the individual. An establishment may not perform or offer any barbering or cosmetology service outside the scope of the establishment's license.

In a medical spa (med spa), an esthetician may assist with advanced treatments, but anything that invades the dermis — injectables, deep peels, certain laser procedures — must be performed under the order and delegation of a licensed physician. The esthetician's cosmetology license does not, by itself, authorize medical procedures.

Common Scope Traps on the Exam

• "A client asks for Botox." An esthetician must refer this out; injectables require a physician. Choosing "perform it carefully" is always wrong.
• "A deep peel for acne scars." Deep peels reach the dermis — outside scope; refer to a medical provider.
• "Dermaplaning add-on." Tempting because it sounds cosmetic, but it is outside the esthetician scope: razor (non-scalpel) dermaplaning requires a Class A Barber license, and scalpel dermaplaning is regulated by the Texas Medical Board — neither is authorized by an esthetician license alone.
• Confusing diagnosis with analysis. An esthetician may analyze skin (type, condition) and recommend services, but may not diagnose a disease or recommend a prescription — diagnosis is a medical act.

Worked example: A client requests treatment for a suspicious changing mole. The esthetician's correct action is to refer the client to a physician/dermatologist — not to attempt removal, not to diagnose. Recognizing the boundary between cosmetic analysis and medical diagnosis is exactly what the scope questions test.

Skin Analysis vs. Medical Diagnosis

The exam carefully separates two activities that sound similar:

• Skin analysis (allowed): determining a client's skin type (oily, dry, combination, normal, sensitive) and skin condition (dehydration, congestion, hyperpigmentation) so you can recommend appropriate products and treatments. Tools like the Wood's lamp support this.
• Diagnosis (not allowed): identifying a disease (e.g., skin cancer, an active infection, eczema) or naming a medical condition. Diagnosing and prescribing are medical acts.

An esthetician who spots signs of a disease or disorder — an inflamed, oozing, or rapidly changing lesion — must not perform the service and should refer the client to a physician. Working over an active infection or open lesion both violates scope and risks spreading disease.

Contraindications: When You Must Withhold a Service

Closely tied to scope is the concept of a contraindication — a condition that makes a particular service unsafe or inappropriate. Even an in-scope service like waxing or a peel must be withheld when a contraindication is present:

• Recent use of isotretinoin (Accutane) or strong retinoids, recent chemical peels, or laser treatment.
• Open lesions, active infections, sunburn, or broken skin in the treatment area.
• Use of exfoliating acids (AHAs/retinoids) before waxing, which can lift skin.
• Known allergies to product ingredients — which is why a patch test is part of the exam's safety subtopic.

The correct response to a contraindication is to postpone or decline the service and document/refer as needed, not to proceed cautiously. Distinguishing a contraindication (withhold the service) from an out-of-scope service (refer to a physician) is a subtle but high-yield exam distinction.

Anchor phrase: epidermis = esthetician; dermis = physician; disease/diagnosis = refer. If you can apply those three rules, the scope questions become straightforward.
