The Wedding in Three Days, a Tender Lid Bump and a Previous Glue Reaction

That appointment does not go ahead. The lesion has the classic appearance of an external hordeolum: a tender, red, pus-centred swelling on the lid margin, which is an active localised bacterial infection of the lid glands, usually staphylococcal. Adhesive, tweezers and my hands would be working directly around a focus of infection; lashes next to a lesion are the last place to place extensions, and manipulation can spread infection to adjacent glands or, via my fingers and tools, to the next client. The watering matters too: tears and discharge at the lash line interfere with cure and increase the chance of adhesive contacting inflamed tissue. I would not squeeze, lance or treat it, because that is outside my scope; I send her to a pharmacist or GP. On timing, a valid patch test needs 24 to 48 hours before a service, so even a settled lid would not make the wedding achievable safely today. The honest alternatives are strip lashes she applies herself, or a set booked once the lid has fully cleared.

The timing is the clue. A reaction beginning 12 to 72 hours after application, with itching and redness confined to where product touched, fits delayed type IV allergic contact dermatitis, most often to the cyanoacrylate monomer and sometimes to pigment, primer or remover. That is different from an immediate type I reaction, which would bring swelling, urticaria or breathing difficulty within minutes and is a medical emergency. Type IV matters because it represents sensitisation rather than a one-off irritation. A patch test two years ago tells us nothing about today, because sensitisation can develop at any exposure, and a later exposure can produce a faster and more severe response. There is also potential cross-reactivity with other acrylates used in nail products, dental materials and medical adhesives, which is worth her knowing. I would advise medical review, flag it prominently on her record as an allergy, and not apply cyanoacrylate to her again unless a dermatologist or allergist clears it after proper testing.

I would document an unusual amount: the lesion's size, colour, position and onset; her description of the earlier reaction; the antihistamine and the feeding; the offer of double payment; and the specific advice given with the reason for it. The key line is that the client was informed the service cannot be performed today and advised to seek medical advice, plus whether she accepted and what alternatives were offered. What I would not do is take the money under a signed waiver. A consent form cannot contract away the standard of care, and the reason for refusing is client safety and infection control, not paperwork. Breastfeeding and a single 10 mg antihistamine are not, on their own, reasons to decline lash extensions, so I would say plainly that they are not the issue, because leaving her believing breastfeeding disqualified her would send her to a source of misinformation. I would also avoid asserting that the other salon caused a contact allergy. I can report what she told me; attributing cause is a medical judgement.
