Hi,
For persistent acne, you should see your doctor to evaluate for an underlying cause such as hormonal imbalance and to assess for any controllable risk factors such as diet, stress, comedogenic skincare products.
Thereafter, appropriate treatment can be offered based on your age, gender, response to previous treatments, suitability and cost considerations.
If assessed to be appropriate and suitable for treatment, a full course of oral isotretinoin often gives excellent acne control and long term benefits to patients.
Hope this helps!
