The Retinoid Client Booked for a Peel
A 41-year-old client books a course of six medium-depth salicylic-mandelic peels for post-inflammatory hyperpigmentation, spaced two weeks apart, starting Saturday. At consultation she mentions she began tretinoin 0.05% cream eight days ago, prescribed by her GP for acne, applied nightly. She also uses a 10% benzoyl peroxide wash twice daily and had a superficial glycolic peel at another clinic three weeks ago. Her Fitzpatrick type is IV. She is keen to start immediately because she has a wedding in five weeks and has already paid a deposit. She asks whether she can simply stop the tretinoin the night before the first peel.
1. Evaluate whether the peel should proceed on Saturday as booked. Identify the specific risks and state what you would recommend and why.

The peel should not proceed on Saturday. Three factors compound risk. First, topical tretinoin thins the stratum corneum and increases transepidermal water loss, so barrier function is compromised after only eight days; standard practice is to discontinue retinoids for roughly one to two weeks before a medium-depth chemical peel, and eight days of use is nowhere near adequate preparation. Stopping the night before does not restore the barrier. Second, nightly benzoyl peroxide plus a 10% wash is itself drying and irritant, and recent use of another exfoliating acid peel three weeks ago means the skin has had limited recovery time. Third, Fitzpatrick type IV skin carries a meaningful risk of post-inflammatory hyperpigmentation, and a compromised, irritated barrier undergoing a medium-depth acid peel raises the chance of unpredictable penetration, prolonged erythema, blistering and dyschromia.
My recommendation: postpone the peel, explain the reasoning clearly and without alarm, and offer a modified plan. Advise stopping tretinoin and the benzoyl peroxide wash now (with GP awareness if the acne regimen matters), substitute a gentle non-exfoliating cleanser and barrier-supportive moisturiser with SPF 50, and reassess in two to three weeks. Only then begin a superficial peel series at reduced strength and short contact time, patch-tested, with a test spot on a less visible area. Discuss the wedding timeline honestly: a cautious superficial series is achievable in five weeks; a medium-depth series starting on irritated skin is not worth the dyschromia risk. Document the advice, the client's decision and the revised plan, and check whether the deposit can be transferred rather than lost.
2. The client insists on proceeding and says she accepts the risks. Outline how you would manage this conversation and what your professional position must be.

Informed consent does not obligate a practitioner to deliver a treatment they judge clinically unsafe. My position is that I will not perform the medium-depth peel on Saturday, and I would say so plainly but kindly, framing it as protecting her outcome rather than refusing her custom.
The conversation should follow a clear structure. Acknowledge her goal (the wedding) and her frustration about the deposit. Explain in plain language what compromised barrier function means and why the risk of dark patches is higher for her skin type, using the analogy of exfoliating already-thinned skin. Be specific about the timeline: what can safely be achieved in five weeks, and what cannot. Offer concrete alternatives: a barrier-repair facial now, a supervised superficial peel series starting in two to three weeks, and a home-care plan that will visibly improve texture and tone by the wedding. Confirm the deposit can be transferred to the revised plan or refunded according to the clinic's published policy.
If she continues to press, I restate the decision once, without debate, and offer to refer her to a clinician who can assess her medically if she wishes a second opinion. I document the discussion, the risks explained, her statements and my recommendation, and I do not ask her to sign a waiver to override a clinical contraindication, because a waiver does not make an unsafe treatment safe. The professional standard is to act within scope and competence, prioritise client safety, and keep the relationship intact through transparency.
