Skin care regime after Accutane treatment?

Dear all,

I have been on Accutane (Acnotin-Isotretinoin) treatment for the past 6 months. I am glad that my condition is recovering :)

During the past 6 months, as advised by my dermatologist, I stopped my normal cleansing/beauty regime and followed the given guidelines.
Thus, I only wash me face with water in the morning and Cetaphil at night.
I did not use any moisturizer, sunscreen, mask and toner throughout my last 6 months of treatment.

Now, as I am approaching the last month of my treatment, I am worried as I do not know what should I do after stop taking the medication.

Should I restart back the normal cleansing/beauty regime?
If I should start back the normal cleansing/beauty regime, how should the regime be? What should and shouldn't I be using and doing?

I would really appreciate any advice from you all.

For those who had previously taken this treatment and had completed it, please let me know what to do after this.

I am worried that if I did the wrong thing, the acne might come back all over again :(

Thank you so much!!
