Which of the following is a common symptom of a nail allergic reaction?

Redness and swelling around the nail is a common symptom of a nail allergic reaction. This response often occurs as the body's immune system reacts to an allergen present in nail products, such as certain ingredients in polishes, gels, or adhesives. When the skin surrounding the nail comes into contact with these substances, inflammation may occur, leading to noticeable redness and swelling.

Other symptoms of an allergic reaction might include itching or pain in the area. The presence of redness and swelling is particularly indicative of a hypersensitive reaction, which is a hallmark of many allergic responses. Recognizing these symptoms is vital for nail technicians, as they must ensure the safety and comfort of their clients by identifying potential reactions and taking appropriate actions.
