Disinfection

Using chemical agents to destroy or inhibit the growth of harmful microorganisms on non-living surfaces and implements, such as soaking combs in an EPA-registered disinfectant solution.

Related: Sanitation, Sterilization, EPA-Registered Disinfectant
Sterilization

The complete destruction of all microbial life, including bacteria, viruses, and spores, typically achieved with an autoclave or dry heat sterilizer for items that contact broken skin.

Related: Disinfection, Sanitation
Universal Precautions

An infection control approach in which all blood and certain body fluids are treated as potentially infectious, requiring the use of gloves and other barriers with every client.

Related: Sanitation, Personal Protective Equipment (PPE)
EPA-Registered Disinfectant

A disinfectant product approved by the Environmental Protection Agency for hospital-grade use, proven effective against specific pathogens when used according to label instructions.

Related: Disinfection, Sanitation
Personal Protective Equipment (PPE)

Items such as gloves, masks, and eye protection worn by the esthetician to protect both themselves and the client from exposure to infectious materials and chemicals.

Epidermis

The outermost, avascular layer of the skin that provides a protective barrier and contains keratinocytes, melanocytes, and Langerhans cells; it is the layer most affected by esthetic treatments.

Related: Dermis, Stratum Corneum, Melanin
Dermis

The middle layer of the skin beneath the epidermis, containing collagen, elastin, blood vessels, nerves, and glands; it provides structural support and nourishment to the epidermis.

Related: Epidermis, Collagen, Elastin
Stratum Corneum

The outermost layer of the epidermis, composed of dead, flattened keratinized cells that form the skin's primary barrier and are shed regularly through desquamation.

Related: Epidermis, Keratin, Exfoliation
Melanin

The pigment produced by melanocytes in the basal layer of the epidermis that gives skin its color and provides some protection against ultraviolet radiation.

Related: Epidermis, Melanocyte, Hyperpigmentation
Collagen

A fibrous protein in the dermis that gives skin strength and structure; its breakdown with age and sun exposure leads to wrinkles and sagging.

Related: Dermis, Elastin, Photoaging
Elastin

A protein in the dermis that allows skin to stretch and recoil; loss of elastin contributes to laxity and fine lines.

Related: Dermis, Collagen
Sebaceous Glands

Oil-producing glands attached to hair follicles that secrete sebum, which lubricates the skin and hair; overactivity contributes to acne and oily skin types.

Related: Sebum, Oily Skin, Acne
Skin Type

The classification of skin based on its oil production and hydration levels, typically categorized as normal, dry, oily, combination, or sensitive.

Related: Skin Condition, T-Zone, Oily Skin
Skin Condition

A temporary or chronic abnormality of the skin such as acne, rosacea, or dehydration, which may require modification of treatment or referral to a medical professional.

Related: Skin Type, Contraindication, Acne
T-Zone

The central area of the face including the forehead, nose, and chin, which typically has more active sebaceous glands and may be oilier than the cheeks.

Related: Skin Type, Sebaceous Glands, Combination Skin
Contraindication

A condition or circumstance that makes a particular treatment inadvisable or unsafe for a client, such as active infection, recent surgery, or allergy to a product ingredient.

Related: Skin Condition, Scope of Practice
pH Scale

A measure of acidity or alkalinity ranging from 0 to 14, with 7 being neutral; skin's natural pH is slightly acidic (around 4.5–5.5), and products should support this barrier.

Related: Acid Mantle, Exfoliation
Acid Mantle

The thin, slightly acidic film on the skin's surface made of sebum and sweat that helps protect against bacteria and environmental damage; disrupted by harsh cleansers.

Related: pH Scale, Sebum
Exfoliation

The removal of dead skin cells from the stratum corneum using mechanical (scrubs, brushes) or chemical (AHAs, BHAs) methods to improve texture and cell turnover.

Related: Stratum Corneum, Alpha Hydroxy Acid (AHA), Beta Hydroxy Acid (BHA)
Alpha Hydroxy Acid (AHA)

Water-soluble acids such as glycolic and lactic acid that exfoliate by loosening the bonds between dead skin cells, improving texture and hydration; can increase sun sensitivity.

Related: Beta Hydroxy Acid (BHA), Exfoliation, pH Scale
Beta Hydroxy Acid (BHA)

Oil-soluble acids like salicylic acid that penetrate pores to exfoliate inside the follicle, making them useful for oily and acne-prone skin.

Related: Alpha Hydroxy Acid (AHA), Exfoliation, Acne
Facial Massage

Manual manipulation of facial tissues using specific movements to improve circulation, relax muscles, and enhance product absorption; must follow proper direction and pressure for each skin type.

Related: Effleurage, Petrissage, Contraindication
Effleurage

A light, gliding massage stroke used at the beginning and end of a facial massage to warm the skin and apply product; performed with gentle, consistent pressure.

Related: Petrissage, Facial Massage
Petrissage

A kneading or compression massage technique that manipulates deeper muscle tissue to relieve tension and improve circulation; used sparingly on the face.

A synthetic lash adhered to a natural lash with cyanoacrylate glue, requiring proper isolation and careful application to avoid damage to the natural lash and eye irritation.

Related: Patch Test, Eyelash Adhesive
Patch Test

A preliminary test in which a small amount of product (such as lash adhesive or tint) is applied to a discreet area to check for an allergic reaction before full application.

Related: Eyelash Extension, Contraindication
Eyelash Adhesive

A cyanoacrylate-based glue used to attach eyelash extensions; it must be used in a well-ventilated area and kept away from the eye itself to prevent injury.
