Green Under the Acrylic
A client arrives for a fill on acrylic enhancements. On the right index finger the product has lifted at the sidewall, and there is a dark green-black patch on the nail plate with a faint odor. The surrounding skin is not red, hot, or swollen, and she is not in pain; she says it itched last week. The tech's plan is to file off the lifted product, put a drop of primer directly on the spot, and rebuild so it "matches." Meanwhile she dropped a metal cuticle pusher on the floor, picked it up, and intends to wipe it with a disinfectant wipe. A pump bottle of 70% isopropyl alcohol sits on the table and is used between clients on the nipper. A client's file from the previous service is in the drawer, saved because it "only touched her nail."
1. Evaluate the finding on the nail and the tech's intended plan. What do you do and what do you not do?

What it likely is: green-black discoloration under a lifted enhancement, with odor and itching, is the classic picture of bacterial colonization of the space between product and plate - the lifted product has created a warm, moist pocket. It is not a stain to be covered and it is not something a nail technician diagnoses.
Do not: apply primer over it and rebuild. Sealing the pocket back up traps moisture and organisms under a fresh product and makes it worse. Primer on compromised plate also stings and can drive product into a place it does not belong.
Do:
- Stop and explain what you see in plain language, without naming a diagnosis.
- Remove the enhancement on that finger so the area can dry and be assessed.
- Discard every file, buffer, and porous item that touched that nail.
- Disinfect reusable implements that contacted it.
- Refer to a physician or dermatologist for evaluation, and do not reapply product to that nail until it is cleared.
Serve the other nine nails only with the client's informed agreement, and only with scrupulous hand hygiene and tool separation - do not carry the same file across. If the client declines the referral, document it.
2. Assess the implement handling: the dropped pusher, the alcohol, the nipper, and the reused file. Which practices fail and why?
Read the worked answer
Dropped pusher: fails. The floor is contaminated. A disinfectant wipe is a surface wipe, not an immersion disinfectant, and it will not reach the edges or any joint. Correct process: clean with soap and water, dry, then immerse in an EPA-registered hospital-grade disinfectant at label dilution for the full label contact time (commonly around 10 minutes), then store in a clean covered container. Until that is done it stays out of service.
70% isopropyl alcohol: fails as an implement disinfectant. Alcohol is a decent antiseptic and a poor instrument disinfectant - it evaporates off the surface, is inactivated by organic soil, and is not the EPA-registered hospital disinfectant with the efficacy claims the rules expect. It also will not do the job on a nipper's hinge.
The nipper: needs the full clean-then-immerse cycle between clients, not a pump and a wipe.
The reused file: fails outright. Files, buffers, and porous items are single-use; they cannot be disinfected, only discarded. A drawer of "her file" is a drawer of cross-contamination.
3. What do you document, what do you say, and what would you change in the salon going forward?
Read the worked answer
Document: date, which nail, a neutral description ("green-black discoloration of the right index plate beneath lifted product, no surrounding erythema reported"), that service on that nail was stopped, that a referral was given, and the client's response. No diagnostic label. Keep the record factual and brief.
Say: "I'm not going to cover this today. When product lifts like this, moisture gets trapped and the nail plate can discolor. I want a doctor to look at it before I put anything back on. I can finish the other nails today, and once you're cleared we start fresh on this one." It is honest, it does not alarm, and it does not diagnose.
Change in the salon:
- A written single-use policy for files and buffers, with a lined waste bin at the station.
- Two covered immersion jars per station so clean and dirty implements never mix.
- Mixing disinfectant at the printed ratio with a measuring cup, labeled with date.
- Periodic lifting checks and client education on home care so pockets are caught early, not at the fill after next.
