The wedding, melasma and the request for six peels
Aisha, 38, Fitzpatrick IV, books a consultation for 'the strongest peel you do' because she is getting married in four weeks. She has symmetrical grey-brown patches on both cheeks and upper lip, present for three years, worse after summer. She has been using tretinoin 0.025% nightly for six weeks and has had two IPL sessions at another clinic, the last three weeks ago. Since the IPL her cheeks are more pigmented and sting when she applies moisturiser. She takes the combined oral contraceptive and is not pregnant. She has no history of keloid scarring but had post-inflammatory hyperpigmentation after a spot on her chin that lasted eight months. She wants a course of six salicylic acid peels before the wedding and asks whether she can stop tretinoin 'for two days' beforehand.
1. What is the likely diagnosis and which factors make aggressive peeling unsafe for Aisha?

The symmetrical grey-brown patches on the cheeks and upper lip, worse after summer, are most consistent with melasma. It is a chronic pigmentary disorder driven by UV, visible light, hormones and inflammation; it is not simply 'dead skin'. Several factors make aggressive peeling unsafe:
- Fitzpatrick IV: darker skin has more active melanocytes and a higher risk of post-inflammatory hyperpigmentation (PIH).
- Previous PIH: her chin spot stayed dark for eight months, showing she is a PIH former.
- Recent IPL: the cheeks are more pigmented and sting, suggesting post-inflammatory hyperpigmentation and a compromised barrier.
- Tretinoin: nightly use increases photosensitivity and reduces the barrier; she has not had a sufficient washout.
- Combined oral contraceptive: can maintain hormone-related melasma.
- Wedding deadline: urgency pushes therapists towards overly strong treatments.
Salicylic acid peels are not first-line for melasma, and six peels in four weeks is not a realistic schedule; peels are usually spaced at least two to four weeks apart. Aggressive peels can burn, cause PIH, blister or scar. She needs a diagnosis confirmed by a GP/dermatologist if uncertain and a conservative plan.
2. Critique her request for six salicylic acid peels and for stopping tretinoin two days beforehand.

Six salicylic acid peels in four weeks is unsafe and not evidence-based for melasma. A peel course needs intervals that allow the barrier to recover; doing them weekly or more often increases irritation, PIH and the risk of a chemical burn. Salicylic acid is lipophilic and useful for oily, comedonal skin, but it does not reliably treat melasma and can irritate dry, stinging skin. Her barrier is already impaired, so any peel now is likely to worsen redness and pigmentation.
Stopping tretinoin for only two days is insufficient. For superficial peels, many protocols advise at least five to seven days; for medium-depth peels, two weeks or more. Because she has been using 0.025% nightly for six weeks and has stinging, she needs a longer washout and barrier repair, not a two-day pause. She also needs a patch test and written consent. I would not book a peel for her now. I would explain that the wedding is four weeks away and that a burn or dark patch would be far more visible than the melasma itself.
3. Outline a safe, realistic plan for the next four weeks.

Start with a gentle consultation and photography with consent. Explain that melasma is managed, not cured, and that the goal before the wedding is calm, hydrated skin and no new pigmentation. Stop tretinoin now and advise a bland, fragrance-free moisturiser and SPF 50 every morning, including indoors near windows; visible light matters in melasma. Avoid heat, steam, waxing on the face and aggressive scrubs. Discuss non-irritating options such as azelaic acid, niacinamide or tranexamic acid, but only after patch testing and with GP advice if she is on prescription treatment. Do not start six peels. If her barrier settles, a single gentle mandelic or lactic acid peel could be considered at least four weeks before the wedding, with a patch test and consent, but it is not essential. Refer to a dermatologist for confirmed melasma and for advice on the combined pill. Book a review in two weeks and document that she declined aggressive treatment after explanation.
