Chest and Back Wax After Starting Isotretinoin
A 22-year-old man books a back and chest wax. He mentions he started oral isotretinoin 20 mg daily eight weeks ago for severe acne and has one cystic spot on his upper back. He also took ibuprofen 400 mg two hours ago for a headache and has a tan from a sunbed three days ago. He wants a clean finish because he is going on holiday in five days. On inspection, his chest is erythematous in patches, with fine vellus hair and a few excoriations from scratching; his back has several inflamed papules and one 1.5 cm cyst. He has no known allergies. He has had waxing before without problems. He is keen to book a repeat appointment before he flies and asks whether warm wax will be gentler than strip wax.
1. Identify the factors that make waxing unsafe today and explain the physiological reason for each.
Read the worked answer
Waxing should not go ahead today because several factors combine to make the skin fragile, inflamed and prone to injury.
- Oral isotretinoin: it reduces sebum production and thins the epidermis, and it impairs barrier function and healing. Waxing can strip the epidermis as well as the hair, causing erosions, prolonged redness and possible scarring.
- Recent sunbed exposure: the skin is already UV-stressed and may be subclinically burned. Waxing adds trauma and increases the risk of post-inflammatory pigmentation and blistering.
- Ibuprofen: this NSAID can reduce platelet function, so there is a greater chance of bruising or prolonged bleeding if the skin is traumatised.
- Active acne and a cyst: these are areas of inflammation and possible bacterial colonisation. Wax can spread infection, rupture the cyst and worsen scarring.
Changing from strip wax to warm wax would not remove these risks; the problem is the skin condition, not the wax type.
2. What service, if any, can you offer, and how would you manage the booking and aftercare advice?
Read the worked answer
I would not perform waxing on the chest or back today. I would also avoid any hair removal that could nick or traumatise the inflamed acne, including close clipping over the cyst unless it can be done without contacting lesions. I would explain that the safe option is to wait until his dermatologist or GP confirms the skin has settled and until the recommended post-isotretinoin waiting period has passed.
I would not take a repeat booking for before his holiday. I would document the refusal and the reasons, give written aftercare advice and suggest he contact his prescriber if the cyst becomes painful, hot or enlarged. For general skin care, I would advise sun protection, avoiding sunbeds and not picking or scratching. A future consultation should include a patch test and a reassessment of skin integrity before any waxing is booked.
3. How would you explain the decision to the client without diagnosing him, and what would you record?
Read the worked answer
I would say that the treatment is not safe today because his acne treatment, recent sunbed exposure, inflamed spots and painkiller all increase the risk of skin damage, infection or scarring. I would avoid saying he 'has an infection' or giving a dermatological diagnosis, because that is outside my role. Instead I would describe what I can see and explain the professional limits of waxing.
I would record the date, the areas requested, the visible redness, excoriations and cyst, the reported isotretinoin and ibuprofen use, the sunbed exposure, the refusal, the advice to seek medical advice and his response. I would note that no wax was applied and that no patch test was carried out. Clear records protect both the client and the salon if he later seeks treatment elsewhere.
