Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation.Other animal coverings, such as the arthropod exoskeleton, have different developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin cutis, skin). In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue, and guards the underlying muscles, bones, ligaments and internal organs.
Yes it is permissible to use products including alcohol to apply on skin, even if the product was Najis as far as you wash it before performing prayers. Alcohol which is used in manufacturing cosmetics is not Najis according the verdicts of many great Shia scholars.
It is permissible to wipe off the water of Wudhu, but it is recommended to leave it to dry by itself. The Hadeeth narrated from the Prophet (SAWA) states: Who performs Wudhu and wipes its water will get one reward, and who performs Wudhu and does not wipe it will get thirty rewards. (Thawab Al-A'maal by al-Sadouq, page 32.)
The doubt in the validity of Wudhu is invalid if it happens after completing the Wudhu. If you are sure that water never reached where it should reach, then you need to make it reach or redo the Wudhu.
If there will be physical contact, without gloves, and you do have an option of seeing a specialist of the same gender, then it would be haram to go otherwise. Unless of course, the specialist of the opposite gender is the only highest qualified dr and your case is serious, needing that level of qualification, then you can, but try to request gloves be worn.
And Allah knows best.

When you do a ghusl, you must make sure that there is nothing that would prevent water from getting to your skin.
Unless of course water would harm a particular area and you must keep it dry. In this case, you perform Ghusl Jabirah.
However, if you can get it wet, and you are able to remove the bandage, even though it could be inconvenient or hurt a bit when taking it off, then try to bear it, do the ghusl, and then use a disinfectant and put a new bandage on.
And Allah knows best.
