Final answer:
Benzoin tincture is the solution applied to protect skin from tape irritation, acting as an adhesive enhancer and providing a protective film.
Step-by-step explanation:
The solution that is applied to the skin to protect it from the irritating effects of tape is benzoin tincture. Benzoin tincture acts as an adhesive enhancer and provides a protective film to reduce irritation caused by frequent changes of tape or adhesive dressings on the skin. Unlike solutions such as hydrogen peroxide which serves as a first aid antiseptic or Betadine (povidone-iodine) that is commonly used as a topical antiseptic before incisions during surgery, benzoin tincture's primary use is to protect the skin in these scenarios.
