Green Discoloration Under a Lifting Acrylic: Fill or Remove?
A client comes in three weeks after a full set of acrylics. Two nails are lifting at the sidewalls, and on the right ring finger there is a dark green-black patch along the free edge where the product has separated from the nail plate. The area has a faint odor, the nail plate beneath feels slightly soft, and the client says it is tender when pressed. She wants a fill only, because her wedding is Saturday and she does not want short nails in photos. The technician's electric file has a coarse bit that has been used on three clients today, the monomer bottle has been left uncapped, and there is no local exhaust at the station. The technician is not wearing a mask.
1. Decide whether to fill or remove, and justify the decision using what the signs indicate.

This is not a fill. The green-black patch, the separation, the soft plate, the odor, and the tenderness together suggest a bacterial or yeast colonization under the lifted product, commonly called green nail, which thrives in the dark, damp space created by a lifted enhancement. Filling over it would trap moisture and organisms, hide the area from view, and allow it to worsen. The tenderness raises the possibility of a more active infection, which is a reason to refer, not to cosmetically cover.
The correct plan: remove the enhancement on the affected nail gently, without drilling into the soft plate; assess the extent; clean and dry; do not apply a new enhancement over a plate that is discolored, soft, or painful. Refer to a physician or podiatrist if there is pain, spreading redness, pus, or if the discoloration extends onto the surrounding skin. The other nails can be serviced if the plate is intact and healthy. Offer the client a natural nail manicure for Saturday and explain the timeline: the discolored area will grow out, and covering it now risks a worse problem on her wedding day and after.
2. Describe the safe removal and nail-plate care steps, including where the electric file and bit fit in.

Clean hands and put on gloves. If product must be reduced, use a fine bit at low speed with light pressure, staying on the acrylic and away from the soft plate; the coarse bit and heavy pressure risk thinning an already compromised nail. Better, soak off or use product-appropriate remover according to the manufacturer's directions, then gently lift remaining product with a plastic pusher rather than a metal tool. Do not pry. Once the plate is exposed, clean it, dry it, keep it short, and apply a light moisturizer to the surrounding skin, not into the separated area.
Disinfect the bit and any reusable implement before the next client; a bit used on three clients today without reprocessing is a cross-contamination problem independent of this case. Discard single-use abrasives. Because the plate is soft and the area is tender, do not buff it smooth with a coarse file and do not apply primer or bonder to broken skin. Explain that the nail will look uneven while it grows out and that keeping it dry and clean is the priority.
3. The client insists on a full set for Saturday. How should the technician respond, and what product and ventilation corrections should be made at the station?

The technician should hold the line and give the client a concrete alternative: 'I can give you a natural nail manicure with polish today, and we can put a full set on once the discoloration has grown out and the tenderness is gone. I will not cover an area that looks like this, because it can get worse under the product.' She can show the client the area in good light and explain that the wedding is exactly why she does not want an infection developing in the week before it. If the client pushes, the technician documents the refusal and the referral.
Station corrections: cap the monomer when not dispensing, since an open bottle releases vapors and attracts debris; use EMA-type monomer and follow the manufacturer's mixing and storage directions; add local exhaust or improve general ventilation so vapors are pulled away from the breathing zone; wear a mask when filing and when working with vapors; use a coarse bit only for product reduction and keep bits clean and disinfected. Document the refusal, the referral, and the service actually provided.
