Makeup Artist key terms

The transfer of bacteria, viruses, or fungi from one surface, tool, or person to another, often by hands, brushes, or shared products. Preventing it is the core purpose of sanitation routines in makeup work.

The routine reduction of visible soil and a large share of microorganisms on skin, hands, and work surfaces to a safe public-health level. It is a lower bar than disinfection and is performed before every client.

The chemical destruction or inactivation of most pathogenic microorganisms on inanimate objects such as brushes, palettes, and tweezers. It requires an EPA-registered product used at the label's stated contact time, after cleaning.

A widely used quaternary ammonium disinfectant concentrate for implements, mixed to the label ratio and used for the full contact time. It is not a skin product and does not replace cleaning before immersion.

A disposable tool such as a mascara wand, lip brush, sponge, or doe-foot that is used on one client and then discarded. It is the standard defense against spreading eye and lip infections between clients.

A puncture-resistant, lidded container for used blades, lancets, and broken glass. In makeup work it holds items like eyebrow razors and dermaplaning blades, which must never go into ordinary trash.

A small application of a product, such as a lash adhesive or hair dye, on a discreet skin area 24 to 48 hours before full use to check for an allergic reaction. Documented consent and timing matter for liability.

A condition that makes a service unsafe or inadvisable, such as an active cold sore, conjunctivitis, open skin, or a recent chemical peel. Recognizing one means declining or modifying the service and referring the client out.

The outermost, avascular layer of skin, built mainly of keratinocytes that mature and shed. Makeup sits on its surface, and its hydration and texture strongly affect how foundation applies and wears.

The outermost sublayer of the epidermis, made of flattened dead keratin-filled cells held in a lipid matrix. Its smoothness or flakiness determines whether product glides or catches on dry patches.

The combined physical and chemical defense of the outermost skin, including lipids, corneocytes, and the acid mantle. A compromised barrier shows redness, stinging, and flaking, so products and prep must be chosen gently.

The slightly acidic film of sebum, sweat, and breakdown products on skin, typically around pH 4.5 to 5.5. Cleansers and toners far from this range can disrupt barrier function and cause irritation before makeup.

The passive evaporation of water through the skin, abbreviated TEWL. High loss signals a weak barrier and dehydrated skin, which looks dull and causes foundation to separate or cling to dry areas.

An oily substance secreted by sebaceous glands that lubricates skin and hair. Excess sebum drives shine and makeup breakdown, especially in the T-zone, while too little leaves skin tight and flaky.

The central facial area spanning the forehead, nose, and chin, where sebaceous glands are densest. It typically needs more oil control and less rich product than the cheeks during prep and setting.

A classification of skin as normal, dry, oily, or combination based on oil production and its distribution. It guides primer, foundation finish, and powder choices; it is distinct from a skin condition such as acne.

A temporary water-deficient state that can affect any skin type, showing tightness, dullness, and fine lines. It is treated with hydration and barrier support, not with heavier oils, and differs from genetically dry skin.

The subtle hue beneath the skin's surface, usually described as cool, warm, or neutral, and sometimes olive. Matching foundation to undertone prevents the grey or orange cast that surface color alone can cause.

The surface color of skin, including redness, tan, or sallowness, which can mask the undertone beneath. A makeup artist reads both to choose a base that looks natural in daylight and in photographs.

A circular arrangement of hues used to predict mixing results. Opposite hues neutralize each other, so green cancels redness and peach or orange corrects blue-toned shadows under the eyes.

A pigmented product applied before foundation to neutralize an unwanted tone, such as green for redness or peach for dark circles. It is used sparingly and only where needed, then blended before base.

The selection of a base whose depth and undertone blend invisibly into the jawline and neck. It should be checked in natural light on clean skin and, for photography, on camera.

The relative lightness or darkness of a color, independent of hue. In makeup it governs contour and highlight placement, since shadows read as lower value and highlights as higher value.

The use of darker and lighter products to sculpt the face by receding or bringing forward areas. Placement follows bone structure and lighting, and the transition must be blended to avoid visible stripes.

Applying a lighter or reflective product to raised areas such as cheekbones, brow bone, and nose bridge to draw light forward. It is the counterpart to contouring and should suit the client's skin texture.

The overall outline of the face, commonly classified as oval, round, square, heart, oblong, or diamond. It guides placement of contour, blush, and brow shape to balance proportions.

The raised curve of the brow where the hair direction changes, usually above the outer iris. Its position and height affect how open the eye looks and how the face is balanced.

Measuring brow start, arch, and tail using the nose bridge, iris, and outer eye corner as landmarks. It creates a repeatable shape that suits the client's features before hair is removed or filled.

A small disposable mascara-style wand used to comb brow hair and separate lashes. It is a single-use item on clients and helps blend brow product for a natural finish.

A product applied before foundation to smooth texture, control shine, or extend wear. Formulas target concerns such as pores, redness, or oil, and incompatible primer and foundation can pill or separate.

A brush with sparse, flat-topped fibers used in a tapping motion to press product into skin. It gives a light, airbrushed finish with cream or liquid products and suits textured skin.

A fine mist applied last to help makeup bond, reduce transfer, and add or remove shine depending on formula. Distance and a light pass matter, since over-spraying can break down base.

An eye technique that sharply defines the crease with a contrasting shade, often over a concealer base. It creates depth and is common in editorial and drag looks where a crisp line is wanted.

Softening transitions between shades so no hard edges remain, achieved with clean brushes and small circular motions. It is the skill that separates polished eye work from unblended color placement.

Fitting a strip or individual lashes to the lash line with adhesive, trimmed to the eye and placed close to the natural roots. Adhesive contact with the eye or lid skin must be avoided.

Makeup designed for a published or conceptual shoot, where story, lighting, and camera take priority over everyday wear. It is planned with the photographer and stylist and often favors strong shapes or color.

A pre-wedding appointment to test the full look, including base, eyes, and wear time, often in similar lighting. It confirms products, timing, and touch-up needs before the event day.

Products formulated to look smooth under high-resolution cameras and strong lighting, avoiding ingredients that flash back white. They matter in film, television, and photography work.

A sculpted appliance, such as a silicone nose or foam latex wound, adhered to skin to change appearance. Its edges are blended with makeup, and removal must protect the client's skin.

A palette of colors used to paint realistic bruises and injuries in stages, from fresh red-purple to older yellow-green. Color sequence mimics the body's healing process for believable effects.

A liquid that dries and puckers skin to simulate scars or cuts. It is flammable, applied in thin layers with ventilation, and removed carefully, never near the eyes.

A pre-service record of contact details, allergies, medications, skin conditions, and prior reactions, signed by the client. It supports informed consent and gives the artist a documented basis for service decisions.

A client's agreement to a service after understanding its risks, alternatives, and aftercare. It is documented in writing, especially for lash extensions, peels, or effects work involving adhesives.

The services and decisions a professional is licensed and trained to perform. A makeup artist generally does not diagnose skin disease or perform medical treatments and must refer such cases out.

The ethical and often legal duty to keep client information, images, and health details private. Sharing photos or before-and-after images requires explicit permission and respect for the client's wishes.

A curated collection of a makeup artist's best work, organized to show range and skill for the jobs they want. It should use credited, permitted images and be kept current.
