When should you not perform a leg waxing service?

The correct response indicates specific medical conditions that contraindicate waxing services. Phlebitis, varicose veins, and diabetes are all conditions that can influence the safety and effectiveness of waxing.

When a client has phlebitis, there's inflammation in a vein that could lead to complications if heat or irritation from waxing is applied. Varicose veins indicate poor circulation, and waxing over such veins can increase the risk of bruising or cause discomfort. Additionally, diabetes can affect the skin's healing process and increase susceptibility to infections, making waxing potentially dangerous.

In contrast, while minor bruising, pregnancy, and sunburns also present concerns for waxing, they do not carry the same level of risk associated with the underlying circulation and skin integrity issues that the conditions in choice B do. For example, waxing over a sunburn can cause pain and further skin damage, but it does not involve systemic health risks in the same way that diabetes can. Therefore, the presence of phlebitis, varicose veins, and diabetes necessitates the most caution, making this the correct justification for avoiding a leg waxing service under those circumstances.
