Rubbing alcohol

Yes, it can be very irritating. Isopropyl alcohol is VERY drying of the skin and can cause reddness, pain and a rash like reaction. 

How could it be irritating if a rubbing alcohol dries fastly on the skin?

in drying it removes the natural oils that keep the skin supple. Chemical reactions don't take very long, so the fact that it dries quickly isn't an indicator. 

Does natural oil is still present on wounds let's say abrasion even the skin outer layer has been peeled off?

If I'm understanding your question correctly, the oils would have be disrupted, but then the alcohol is going onto "raw", open, or wounded flesh thus exacerbating any problems you have. A single wipe with Isopropyl won't cause any damage (unless you're allergic) and will help kill various and sundry micro-organisms that you don't want there. 

However, the facts ARE the rubbing alcohol CAN and DOES cause skin damage. In the past, it was used as a 'wipe bath" to help reduce fevers (since it dries and cools so quickly). However, this practice was abandoned as the skin reactions were too great. 

Does rubbing alcohol could alter the healing process of the wound, how? All I know is that alcohol is fast drying and could elliminate dirt and grease that could harbor infection. How could be an alcohol can be contraindicated in wound cleansing if the exposure of the raw surface of the skin is only on a very short of time and beside it prevents infection also?

I have the feeling that I'm missing something in the thrust of your questioning. 

The initial question was "can it cause irritation" and the answer is YES. 

Radition therapy, which saves lives, also has adverse side effects and causes significant irritation as well, BUT, we continue to use radiation therapy and work through or around those side effects. 

Alcohol is similar. It has some side effect draw backs, but the overall benefits are such that we work with, and around such side effects. In most cases where we would use alcohol as a wound wash to remove bacteria and such, we would also then wash the wound and apply a topical ointment that would help prevent the drying and/or replace the lost skin oils and prevent the wound from drying out too quickly. 

As with many drugs and medications, PROPERLY used, in the appropriate doses or quantities, the benefits are great, despite known side effects of the medication. 

If misused, such meds/drugs can cause great damage even unto death. 

So, alcohol, under normal circumstances is PART of the treatment, but not the whole of the treatment. It's side effects, when properly used are relatively minimal and can be negated by using proper procedure and materials. 

Hello, my Clinical Instructor told me that never use Isopropyl alcohol cause after 20years you'll see the reaction. She told me that these can enter our red blood cells that can turn into a cancer. Is that true?
