Type 2 Diabetes, Warfarin and a Full-Leg Hot Wax
A 58-year-old woman with type 2 diabetes books a full-leg hot wax. She was diagnosed 12 years ago, her last HbA1c was 8.9%, and she describes numbness and tingling in both feet. She takes metformin and warfarin for atrial fibrillation; her INR was 2.5 at last month's check. On the legs there are prominent varicose veins on both calves, a healing shaving nick on the left shin, thin dry skin and several unexplained bruises. She has not been waxed for six years but says it 'was fine then'. The salon's wax heater is set to 68 °C and the therapist plans to use hot film wax strips, finishing with a post-wax oil containing fragrance. The client has a hospital appointment in two days and wants 'smooth legs for the consultant'. She has no known allergies and has signed the consent form.
1. Identify the risk factors in this client and explain how each one changes your treatment plan.

Each factor changes the plan:
- HbA1c 8.9%: poor glycaemic control delays healing, increases infection risk and makes skin more fragile. Any skin trauma matters more than for a non-diabetic client.
- 12-year duration with numbness and tingling: suggests peripheral neuropathy. She cannot reliably feel wax temperature, so a burn could occur without her noticing - a serious risk on a diabetic leg.
- Warfarin, INR 2.5: therapeutic anticoagulation means easy bruising, prolonged bleeding from any nick, and a risk of skin tearing when strips are removed.
- Varicose veins on both calves: direct heat and wax over dilated veins risk thrombophlebitis, pain and bruising; avoid those areas.
- Healing shaving nick on the left shin: broken skin is a local contraindication to wax in that area.
- Thin, dry skin and unexplained bruises: fragility plus possible over-anticoagulation; bruises of unknown cause need medical review.
- 68 °C hot film wax: appropriate for healthy skin, too hot for thin, neuropathic skin with poor circulation.
- Fragranced post-wax oil: adds sensitisation risk on compromised skin; use a plain, fragrance-free aftercare product.
2. What would you do about the wax today, and what alternatives could you offer?
Read the worked answer
Do not do the full-leg hot wax today.
- Exclude the shin (broken skin), both calves over the varicose veins, and every bruise.
- Hot wax at 68 °C is not appropriate for her: with neuropathy she cannot give reliable feedback on temperature, and thin skin burns easily.
- The safest position is to decline leg waxing today and explain why: burns, skin tears, bruising, infection risk and slower healing.
- Refer before treating: ask her to see her GP or diabetes team about the unexplained bruises, her INR and the numbness, and to confirm whether waxing is acceptable. A podiatrist can assess neuropathy and circulation.
- If, after clearance, you treat: use warm (not hot) wax or sugar paste at the lowest effective temperature, test a small area, check sensation beforehand, work in small sections, support the skin, remove against the hair growth with the skin held taut, and stop at the first sign of skin lifting.
- Alternatives today: trimming, or a patch-tested depilatory cream on intact skin only - though fragile skin may sting, so patch test 24–48 hours ahead.
- She has a hospital appointment in two days: suggest she raises the bruises then.
3. What aftercare and referral advice would you give, and what would you record?
Read the worked answer
Aftercare and advice:
- No hot baths, saunas, tight hosiery or exercise for 24 hours (if treated).
- Fragrance-free emollient, and SPF if the legs are exposed.
- Do not scratch or pick; watch for redness, heat, swelling or discharge and see the GP or diabetes team if present.
- Daily foot checks, well-fitting footwear and no barefoot walking - standard diabetic foot care.
- Report any new or worsening numbness, or unexplained bruises, to her GP.
Referral: GP or diabetes team for the bruises, INR review and neuropathy assessment; consider a podiatrist. Do not treat until cleared.
