The Lifted Fill and the Green Spot
A client comes in at three weeks for an acrylic fill. Two nails are lifting along the sidewalls. On the right ring finger, under the lifted edge, there is a small dark green-black spot with a slightly moist pocket. She says 'just fill over it, I have a wedding Saturday.' On your table, the monomer dish is uncovered from yesterday, and you notice the last few sets have come out gummy and bubbly, with lifting at the sidewalls within a week. Your appointment is 45 minutes, and she wants a full set of gel polish on top.
1. What do you do about the green-black spot?

Remove the enhancement on that nail and do not re-cover it. A green-black spot under a lifted edge suggests moisture and bacterial activity trapped in the pocket; sealing it under acrylic or gel encloses the problem, hides its progress, and can make it worse. You also cannot diagnose what it is, so refer her to a physician or dermatologist and note the referral.
Explain it in plain terms: 'There is something under this nail that shouldn't be sealed in. I can remove the product and refer you, but I can't cover it.' You may still service the other nine nails if the skin is intact, with separate implements, and you can give her a polished look on the unaffected nails for the wedding. Document location, appearance, removal, and referral. The exam point: the wedding deadline does not change the clinical call.
2. Diagnose the pattern of lifting and gummy, bubbly product and list the corrections.

A repeated pattern across clients points to technique and product control, not just one client's habits. Likely contributors:
- Prep failure: cuticle tissue or oil left on the plate, or no proper dehydrating step, so product bonds to debris instead of nail.
- Ratio: too wet a bead causes shrinkage, bubbles, and weak cure; too dry causes poor adhesion and lifting. Aim for a bead that holds its shape and does not run.
- Application: flooding the sidewalls and cuticle area creates a thin, weak edge that lifts; product should be thin at the sidewalls and capped at the free edge.
- Contaminated or evaporated monomer (see next task) throws off every ratio you mix.
Correct the prep sequence, retrain the bead ratio, keep sidewalls thin, cap edges, and give aftercare instructions (no soaking, gloves for cleaning). Then track the next few fills to confirm the fix.
3. What is the problem with the uncovered monomer dish, and how should monomer be handled?
Read the worked answer
Monomer is volatile. Left open, its components evaporate, which changes the liquid's chemistry so the ratio you were taught to use no longer produces the same set - that alone can explain gummy, bubbly, slow-setting product. An open dish also collects dust, filings, and cured crumbs that act as contamination and as weak points in the finished enhancement. There is also a vapor and flammability issue: monomer vapor is an inhalation irritant and a fire risk near heat or flame.
Handle it by keeping the container capped when not actively dispensing, pouring only what you will use into a small dappen dish, discarding leftover liquid rather than pouring it back, and replacing contaminated or thickened monomer. Ventilate the area and keep it away from open flame and heat sources. Store according to the SDS. The judgment point is that 'it still looks like liquid' does not mean it is still usable.
