As far as helping your face...
The body location at which people see effects or feel effects is virtually always part of the compensation pattern and thus should not be treated.
In this case most people have those ill effects in or, at their heads because there are meningeal adhesions pulling from the spine up into the head -- not always the case but quite the majority of cases. Occasionally it is the reverse, where meningeal adhesions in the head pull down the body causing its problems and nothing else works to correct that difficulty.
If you check some of the ABC™ practitioner web sites you will see patients' faces look much better after treatment even when endonasal treatment (direct treatment of the head) was not done. That is this mechanism in action.
The point is that you have to do the correct thing for the body before you. Then the face and everything else will be just fine.
An example is a practitioner who was getting NCR for about a year. Happened upon ABC™, learned it and started treatment of his own body. Within 5 or 6 treatment he no longer needed any cranial treatment at all. Just properly correcting his lower body structure properly eliminated all the things in his head he had been trying to get treated.

Next,
It very much is unlocking something in the spine will unlock the head as noted above. Try this page

Putting balloons up your nose is a misleading but not inaccurate statement. The finger cot is firmly tied to a sphygmomanometer bulb and can only come off it the practitioner is negligent in attaching it.
Inhaling that balloon might be a problem if it was not firmly attached. Same answer as the sentence above.

As far as the difference between ABC EndoNasal™ and NCR,
As noted, ABC EndoNasal is indeed the same basic procedure for insertion of the balloon into the nasal conchae, the difference is in the diagnostics and being able to correctly identify which nasal concha or conchae need to be treated. More importantly for this discussion, it identifies which need to be untreated because they are out of place as part of the compensation pattern.
This is a huge difference as it eliminates treatment of compensations which,
a. Breaks down the body's ability to compensate and makes the body worse overall even if it changes the pattern and relieves some local condition. And,
b. Is the source of the nasty reactions people have to any type of endonasal treatment when they have them.
Keep in mind, if you get some sort of body treatment and later have some ill effect -- even if it is 6 months or more later -- it is likely that the treatment was the factor that caused your body to go funky. The mechanism is the breaking down of a compensation pattern, the body worsening and never being able to compensate well enough again.

According to quite a few professional practitioners, ABC™ even done in sloppy manner is so much better than anything else in the field of manipulation that it is a tough thing to understand how much better well done ABC™ works. (Bane of my life as many practitioners never take the time to get to expert level application.)
Given that observation:
The truth of the matter is that you (plural) should get with a friend or partner, learn ABC™ and treat each other. You will not get doctor level education but you will get excellent technician level education.
Learning in that way and using that with a friend or relative you will get adequate (or better) treatment in both quality and quantity, save a ton of money in the long run (even the fairly short run since you will recover the cost in less than a year compared to paying a pro to treat you) and you will have it for the rest of your life. Because of that, within a year or less you will be healthier than you can ever imagine before getting it done.
If you get stuck you find a pro who is certified and get your body cleaned up. You will find that any ABC™, even done half-well, when added to once or twice a month well done ABC™ well gets your body going and healthier than you have dreamed it could be.

As for being able to learn it, we have plenty of Amish who have learned ABC™ to treat family and friends and do an excellent job.
They only have an 8th grade education but get a basic bone anatomy course we sell, a good dictionary and the ABC™ Core Curriculum Program. Then, they make sure to look up every word they do not fully understand and do just fine.
If they can, so can you.
