Make sure you all are taking breaks after a few weeks, or your eyes will get use to it and not respond anymore.

Just changing your formula (ingredients) would suffice and allow you continued success right?

You wouldn't have to stop at all. That way if your eyes ever started to get used to the first formula, you would have your second formula to use, then maybe switch back after a while to the first formula.

No, its not the ingredients, it the effect they have on the eye. If the effect continues, the eye will stop responding eventually.

So how does that work? When one gets used to something usually a change is all that is needed, until the body gets used to that. Like dosages of medicine and stuff.

I haven't read too much on eyecolorboard that says a break is needed. Unless I missed those threads. People just switched formulas. Do you have any links?

I know a short break is needed from inhibitors during the day to allow melanin to be released so it can be destroyed/changed by your formula, though. It is a slow release though. Is this the break you are talking about? I would think different lightening agent would work when one stopped.
