Which condition allows for the application of wax?

The application of wax is suitable for the condition of a nevus, which refers to a congenital skin mark or mole. Generally, when a nevus is stable and not inflamed or problematic, it does not pose a risk for irritation when waxing. Estheticians can safely perform waxing in areas where there are nevi, provided these growths are assessed as harmless and non-reactive.

In contrast, conditions such as dermatitis and psoriasis could lead to skin irritation or exacerbation of symptoms if wax were to be applied, as both are characterized by inflammation and sensitivity. Acne is another condition that warrants caution, as waxing can potentially aggravate the existing breakouts, leading to further complications.
