Thank your for your questions. Your acne skincare regime sounds like a decent acne prevention skincare for any average person, but it's important to understand that a good acne skincare regime depends on your individual skin type and acne severity. It is impossible to give you skincare advise without acne proper assessment.
Furthermore, from what you have described, you may have acne nodules or cysts below the skin surface. These may require medications, injections or even lasers to the tackle the problem.
Please see your skin/aesthetic doctor for assessment and treatment. Hope this helps!
