Which condition should not be present for a dermaplaning treatment to be suitable?

For a dermaplaning treatment to be suitable, the presence of cold sores is a significant contraindication. Cold sores, caused by the herpes simplex virus, indicate an active outbreak that can easily be exacerbated during the dermaplaning procedure. The treatment involves using a surgical scalpel to remove the outer layer of dead skin cells and vellus hair from the face, which can lead to broken skin and increase the risk of the virus spreading, leading to complications.

In contrast, conditions like moderate acne may require careful consideration but do not outright disqualify a client from receiving dermaplaning, as long as there is no active pustular acne. Dry or oily skin can also be managed during the treatment, as dermaplaning can help enhance the overall texture and appearance regardless of skin type. Thus, the presence of cold sores directly undermines the safety of proceeding with dermaplaning, making this the correct answer in identifying a condition that should not be present.
