Diagnosing acne is usually pretty straightforward. A medical professional will look at your skin and advise if what you’re experiencing is acne or another skin condition. For mild acne, a pharmacist can usually help you to diagnose this, whereas a clinician is usually the best person for a diagnosis of more severe cases of acne.
If you’re experiencing adult acne that seems to have started suddenly, then this should be mentioned during your consultation, as it can be a symptom of an underlying condition or hormonal changes, such as PCOS (polycystic ovary syndrome) or menopause.
