Does a patient have to avoid dairy products if he/she is acne-prone?

I think the question should be more aptly rephrased as “What type of laser treatment is suitable for sensitive and acne-prone skin? ” To this point, I must say a lot of this depends on the clinical experience of your doctor. Textbook doctors may sometime run into real-world problems as most of us doctors experienced when we first started treating patients. After more than 10 years, we learn from the exceptions and when textbook protocols don’t apply exactly. The Asian skin type is rather different from Caucasian skin.

If I were in your shoes, I’d definitely NOT stop taking isotretinoin until I’ve finished the course. Many studies have shown that the risk of acne relapse is much higher if you don’t complete the course. The total dosage you need to take depends on your BODY WEIGHT as well. Tapering your dosage wise, please speak to your doctor. Again, if I were you, I’d just stick to the dosage that he has placed you on, since it appears that you are not suffering any adverse effects (apart from dry lips, which is very common).
