Glycolic Peel Ten Days Before a Sun Holiday
Priya, 34, Fitzpatrick skin type III, has melasma on both cheeks and wants a 'strong' glycolic peel before her holiday to Spain. She is booked for a 30% glycolic peel, which the salon offers as a course of four. She had one salon peel two years ago with no problem, uses a retinol night cream twice weekly, and takes doxycycline for acne. She is flying in ten days and plans sunbathing. She wants to look 'glowing' in photos and has already paid. She has no active cold sores but has a history of cold sores. Her skin is slightly dry but intact, and she has not had a patch test at this salon. The therapist has a 20% glycolic, lactic acid, LED, and a hydrating facial available.
1. Identify the risk factors and decide whether the 30% glycolic peel should go ahead today.
Read the worked answer
The 30% glycolic peel should not go ahead today. Priya has several compounding risks: doxycycline can cause photosensitivity; retinol use twice weekly increases skin permeability and irritation; melasma in skin type III is prone to post-inflammatory hyperpigmentation; she is flying to a sunny destination in ten days and plans to sunbathe; and she has a history of cold sores, which can be reactivated by skin trauma. She has also not had a patch test at this salon. A 30% glycolic peel is a strong concentration and the combination of recent retinol, antibiotic photosensitivity and imminent UV exposure makes an adverse reaction or PIH likely. I would decline the peel and explain why.
2. Explain the reasoning around photosensitivity, medication, retinol and infection risk.

Doxycycline can make the skin more sensitive to UV, so a peel followed by sun exposure increases the risk of burns and pigmentation. Retinol accelerates cell turnover and thins the stratum corneum, so the peel will penetrate more deeply than expected; this raises the risk of redness, blistering and scarring. Melasma is already driven by UV and inflammation, so aggressive peeling close to a sun holiday can make it darker, not lighter. The history of cold sores matters because peel-induced trauma and stress can trigger herpes simplex, and an active outbreak would be a contraindication. A patch test is needed at least 24-48 hours before any peel, and it would not remove these systemic risks.
3. What treatment and aftercare plan would you recommend, including timing before travel?
Read the worked answer
I would offer a hydrating facial or LED today, provided she has no photosensitivity from doxycycline and gives consent; I would avoid any exfoliating acid. I would advise her to stop retinol for at least five to seven days before any future peel and to avoid sunbeds and direct sun. I would recommend SPF 50, a hat and shade on holiday, and I would not book a peel until at least two weeks after she returns, when her skin is calm. At that point I would patch test and start with a lower-strength lactic or 20% glycolic peel, with a course rather than one strong treatment. I would document the refusal, the alternatives and the aftercare advice.
