Isotretinoin, a Cold Sore, and a Prepaid Package
A 41-year-old client books a brow wax, lip wax, and full-leg wax nine days before a vacation. Her intake form says she started isotretinoin 40 mg daily three months ago and expects three more months of treatment; she also applies tretinoin 0.05% cream to her face every night. She mentions a "cold sore" on her upper lip ten days ago that has now crusted, and that she used a tanning bed yesterday. She is Fitzpatrick type II and says her skin "always burns." She has prepaid a package that expires in three weeks and asks you to "just do what you can."
1. Sort the requested services into do and decline, with your reasoning for each.
Read the worked answer
Brow and lip wax: decline. Full-leg wax: decline. Reason is physiologic, not preference.
- Systemic isotretinoin reduces sebum, thins the stratum corneum, and slows healing for months. Topical tretinoin does the same locally to the face. Wax grips skin as well as hair; on thinned, fragile tissue it can avulse epidermis - erosions, oozing, post-inflammatory hyperpigmentation, and infection or scarring risk.
- Legs are not exempt: isotretinoin is systemic, so the same lifting risk applies to the legs, not just the face. Common dermatology guidance is to avoid waxing during treatment and for roughly six months after the last dose; follow her dermatologist's clearance.
- Yesterday's tanning plus type II skin adds subclinical erythema and photosensitivity, which further weakens the barrier today - another reason not to wax.
What I can offer today: brow grooming that does not pull on treated skin (scissors, or a patch test on a small area first), a facial that avoids exfoliation and extractions, sun-protection guidance, and a rescheduled wax appointment after written dermatologist clearance. The prepaid package is a business problem, not a clinical one - extend or transfer it rather than perform an unsafe service.
2. How does the crusted lip lesion change the plan, and what is your hygiene reasoning?

Defer all lip-area work until fully healed.
A crusted lesion ten days old on the lip is most consistent with herpes labialis, and it can still be contagious after the crust forms - viral shedding persists beyond the visible stage. An esthetician does not diagnose, but the judgment is clear:
- Direct contact spreads it: the service area is the lesion, and wax strips, threads, and gloved fingers can carry virus.
- Autoinoculation is real: fingers to eye or to a break in the skin can seed a new site.
- Trauma reactivates: waxing near a recently active site can trigger another outbreak.
So: no lip wax, no brow wax overlapping the area, no extractions nearby, gloves on, hands washed before and after, no touching the face and then tools. Refer to a physician if outbreaks are frequent, and reschedule once the skin is fully re-epithelialized with no crust or vesicle. Say it as a service limitation, not a diagnosis: "I can't wax over skin that isn't healed."
3. The package expires in three weeks and she is pressing you. How do you handle the conversation and the record?
Read the worked answer
Separate the commercial problem from the clinical one, and solve the commercial one.
- Acknowledge the money first: "You've paid for this and I want you to get it." Then extend the expiration, transfer the balance to another service, or refund the wax portion - that is within the salon's control. Her skin is not.
- Explain the mechanism once, briefly: the medication thins skin for months, waxing can take skin with the hair, and healing is slowed - this is exactly when a small service becomes a scar.
- Do not offer a release form as a workaround. A signature does not make fragile tissue durable.
Document: intake answers verbatim (isotretinoin dose and dates, topical tretinoin, tanning, Fitzpatrick type), objective findings (crusted lesion on upper lip, erythema), services declined and why, alternatives performed, the reschedule window, and the package adjustment. Note that referral, not diagnosis, was given. If she returns with clearance, record the clearance date before waxing.
