Personally, I’d say that stopping acne treatment after 2 weeks is a bit premature.
We typically tell patients that for acne treatment, give it a good 2 – 6 weeks to give the treatment some time to work.
The caveat is if you’ve noticed that the treatment was actually aggravating your skin somehow, in which case, you should stop and consult a doctor earlier.
Stopping all treatment, and just washing your face is unlikely to resolve the acne outbreak either.
You may want to try the treatment for at least 3 – 4 weeks, and if you still find that it isn’t doing anything for your acne at all, seeking a second opinion at that point may be warranted.
If your acne is as bad as it sounds, and scarring is an issue, I’d actually be inclined towards Accutane sooner, rather than later, if I were in your shoes. We previously wrote about Accutane, as well as various acne treatments here.
