Is it common to have more acne as an adult than during childhood/adolescence? What are some causes in adults?Yes, common.

Does the location of the acne tell you about the cause? If acne mostly occurs on lower cheeks, along jaw line, chin – this is most likely hormonal in female, and related to shaving in male.
How does a dermatologist determine the right regimen for treating acne?By examination of patients at the clinic. Based on the history, morphology, distribution, age, other medical problem, dermatologist will discuss right regimen with patients and make a treatment plan together with patients.
Is hyperpigmentation the same as acne scars? What makes it different?No, many different types, based on the causes, color, distribution. Patients needs to see dermatologist for evaluation if it’s not from acne.
