Tretinoin, Doxycycline, a Sunburn, and a Glycolic Peel
A 28-year-old client (Fitzpatrick III) books a 60-minute appointment: brow and upper-lip wax plus a "light" 30% glycolic peel. Her intake form notes nightly tretinoin 0.05% for eight months (last used two nights ago), a course of isotretinoin that finished seven months ago, doxycycline for acne, a cold sore that healed ten days ago, and a sunburn from a Florida vacation three days ago that is still pink and peeling across her forehead and nose. She wants everything done today because she has a reunion on Saturday.
1. Sort the requested services into perform / modify / do not perform today, with the physiological reason for each.

Do not perform - waxing:
- Tretinoin thins the stratum corneum and slows barrier recovery; wax can lift or tear skin that looks normal. Standard practice is to stop retinoids about 5–7 days before waxing (physician guidance varies).
- Isotretinoin is the bigger red flag. Waxing, exfoliation, and dermabrasion are conventionally avoided for at least 6 months after the last dose because of fragile, poorly healing skin. She is at 7 months - borderline, and combined with the tretinoin she is not a candidate today.
- The sunburn is an active injury. Waxing over pink, peeling skin removes a compromised barrier and can cause post-inflammatory hyperpigmentation on Fitzpatrick III skin.
- Recent cold sore (10 days): trauma near the lip can trigger reactivation, and viral shedding can occur without a visible lesion.
Do not perform - peel: glycolic acid on tretinoin-thinned, sunburned skin risks over-exfoliation, blistering, and PIH. Doxycycline adds photosensitivity, raising the risk from any resurfacing.
Perform today: a gentle, non-exfoliating hydrating service - cleanse, cool compress, hyaluronic or ceramide moisturizer, SPF - plus home care and a rebooking.
2. What must be documented, and what exactly do you tell the client?
Read the worked answer
Document:
- Every medication with date ranges (tretinoin last used two nights ago; isotretinoin stopped 7 months ago; doxycycline current).
- The sunburn with its date and location; the cold sore with its date.
- The specific services declined, the reason, and that a modified service was offered instead.
- Fitzpatrick type and any patch test performed.
- Referral to her physician or dermatologist for clearance on waxing and resurfacing.
Say it in cause-and-effect language: "The retinoid and the recent sunburn mean your skin's outer layer is thinner and healing more slowly. Waxing or a 30% glycolic peel today could tear the skin or leave dark marks that take months to fade. I can do a calming treatment today, and we'll book the wax and peel once the burn has fully healed and your skin has been off the retinoid for about a week."
Offer a concrete date, a patch test 24–48 hours before the rescheduled wax, and a written aftercare sheet with daily SPF. Declining and rebooking is the service, not the failure to sell.
