Which of the following is a contraindication for dermaplaning?

Blood thinners are a contraindication for dermaplaning because they can increase the risk of bleeding during the procedure. Dermaplaning involves using a surgical-grade scalpel to gently exfoliate the top layer of dead skin cells and fine vellus hair from the face. In clients who are on anticoagulant medications, the skin may be more prone to damage and bleeding from the fragility and sensitivity that can occur. This underscores the importance of assessing a client's medical history and current medications before proceeding with dermaplaning, ensuring safety and minimizing potential complications.

In contrast, dehydrated skin and conditions like rosacea do call for caution and may require modified techniques or additional care during treatment, but they do not outright prohibit dermaplaning. Normal skin typically does not present any significant concerns for this procedure.
