How to Apply Stage Makeup Safely

Begin with labels and a clean station
Apply stage makeup safely by using intact products exactly as labeled, washing and drying your hands, cleaning the work surface and tools, and keeping each cosmetic in the area for which it is intended. Stop immediately for irritation, pain, eye symptoms, swelling, breathing trouble, or other signs of a reaction.
Bold color does not require bold improvisation with an unlabeled jar from the back of somebody's kit.
Check every product before the show
Read directions, warnings, ingredients, storage, expiration or replacement guidance, and eye or lip restrictions. Confirm that adhesives, removers, glitters, color products, and sprays are intended for the exact use. Do not use a lip product around the eye or craft material on skin because the color happens to match.
FDA advises protecting cosmetics from temperature extremes and discarding products that change color or smell. Keep containers clean and closed. Mark the open date when useful and follow the maker's replacement guidance.
Use cosmetic and adhesive testing guidance well before performance day when the product label calls for a sensitivity step. A prior uneventful use does not guarantee a future reaction.
Protect the eye area
FDA says to wash hands, use clean eye-area instruments, avoid sharing cosmetics, and avoid eye cosmetics during an eye infection or inflammation. Discard eye cosmetics used when the infection occurred. Use only products intended for the eye area.
Apply while seated or standing steadily in a well-lit, stationary place—never in a moving vehicle. Keep applicators away from the eyeball and stop if irritation begins. Do not add water or saliva to dried mascara.
Contact-lens wearers should follow their eye-care professional and lens-product instructions. Eye pain, injury, discharge, light sensitivity, or vision change needs prompt medical attention, not another layer of liner.
Prevent cross-contamination
Do not share personal eye cosmetics. For products designed to be decanted, use a clean spatula onto a clean palette and apply with a clean tool. Never double-dip a used applicator into shared product. Keep clean and used tools physically separate.
Follow brush and tool cleaning procedures between people and after the show. Single-use applicators are single use; the clue is doing unusually heavy work in that sentence.
Use sprays and adhesives as directed
Use aerosols or sprays only with the ventilation, distance, ignition precautions, and protective steps on the label. FDA advises using sprays in well-ventilated areas and away from smoking or open flame.
For lash, wig, prosthetic, or body adhesive, confirm the intended surface and remover. Keep it out of the eye, mouth, broken skin, and hair unless the label explicitly allows that use. Never substitute household or craft glue.
Remove everything without forcing it
Pack the matched remover and follow gentle stage-makeup removal. Do not pull lashes, prosthetics, tape, or glued edges from dry skin. If a product will not release by its instructed method, stop and seek qualified help.
Record the exact product and symptoms after any suspected reaction and consult a healthcare professional. In an emergency—especially breathing difficulty, facial swelling, faintness, or rapidly worsening symptoms—seek emergency care.
