When NOT to Treat
Recognising contraindications

One of the most important skills in aesthetic practice is recognising when not to treat. This includes situations where the diagnosis is unclear, the skin is inflamed, or there is a high risk of complications such as post-inflammatory hyperpigmentation.
Patients may request treatment even when it is not appropriate. In these situations, clinical judgment must take priority over patient expectation. Treating uncertain or unstable skin can worsen the condition and lead to long-term complications.
Common examples include performing peels on inflamed acne, treating undiagnosed pigmentation, or attempting to remove lesions without clear identification.
Knowing when to pause, reassess, or refer is a key marker of a safe and competent practitioner. It reflects not hesitation, but clinical maturity.
Clinical Takeaway
Saying "no" to a patient is not a failure—it is a hallmark of clinical maturity and patient safety.
