Isotretinoin, a Wedding, and a 30% Glycolic

None of the three as requested.

• Brow and lip wax. Isotretinoin shrinks sebaceous glands and thins the epidermis while it works. Waxing is mechanical avulsion: the strip takes hair and surface skin cells. On retinoid-compromised skin the strip can remove epidermis down to an erosion, leaving a weeping, bleeding patch that heals slowly and may scar or hyperpigment. Upper lip is the thinnest, most fragile site on the face and the classic location for this injury. Standard practice is to defer waxing during treatment and for roughly six months after the last dose.
• Upper lip wax plus cold sore history. Add a second reason: lip waxing is a well-recognized trigger for herpes labialis reactivation in someone who reports a sore under stress. Even without isotretinoin I would question this one.
• 30% glycolic on flaking, erythematous skin with two open picked sites. Flaking plus erythema means the barrier is already impaired. Adding a strong acid raises the risk of a chemical burn, infection at the open marks, and post-inflammatory hyperpigmentation. Never apply an acid exfoliant over excoriations.

What you can do: a gentle, non-exfoliating, non-traumatic service (double cleanse, tepid compresses rather than hot steam, calming hydrating mask, light massage away from lesions, moisturizer, SPF 30+), plus optional minimal stray-hair cleanup with tweezers on a test spot if the skin tolerates light traction.

A verbal report from a prescriber does not transfer your judgment to the prescriber.

• 'The medication is working great' is a statement about efficacy, not clearance for mechanical or chemical trauma. The two are not the same sentence, and clients often hear the second one.
• You may ask for written clearance, but clearance does not obligate you to perform a service you believe is unsafe. Estheticians routinely decline services and are expected to.
• Hold the line on the relationship, not just the service. Script it as what you will do, not as a lecture: 'I'm not going to wax or peel this week. The skin is already thin and flaking from the medication, and a wax strip can take skin with it. Here is what I can do safely in 60 minutes so you still walk out glowing.'
• Offer a concrete path forward: book her for waxing at least six months after she finishes treatment, and a corrective exfoliation only after she has been off the medication and her barrier is intact.

Reasoning: the liability and the injury both land on the person holding the wax strip. The client's disappointment is a today problem; a stripped, scarred upper lip is a months-long problem.

Documentation

• Objective intake findings: current isotretinoin 40 mg daily, duration, dryness, flaking, erythema, two healing excoriations, reported history of herpes labialis.
• Services declined and the specific reason given for each.
• Alternative service performed and products used.
• Client's statements, including the dermatologist reference, and her response to the refusal.
• Note that you advised when it would be safe to rebook.

Aftercare for a client with a compromised barrier two days before an event

• Gentle non-foaming cleanser, no scrubs, no acids, no at-home peels, no retinoid layering on top of what her prescriber ordered without his direction.
• Barrier repair moisturizer, bland occlusive where flaking, and broad-spectrum mineral SPF 30+.
• No picking; if a cold sore tingles, she should contact her prescriber immediately rather than wait.
• Avoid hot yoga, saunas, and alcohol-based toners for the week.

Judgment: 'look good Saturday' is a plan question. Flake-free and calm on Saturday is achievable with hydration; it is not achievable with a peel and a wax, and telling her that honestly is the service.
