Question: 1 / 400

What is a common symptom of a skin allergic reaction?

Itching and dryness

Redness and swelling

A common symptom of a skin allergic reaction includes redness and swelling, which indicates inflammation in response to an allergen. When the skin comes into contact with a substance that triggers an allergy, the body’s immune system reacts, leading to an increase in blood flow to the affected area. This increased blood flow results in redness, while the release of histamines can cause the skin to swell as fluid leaks into the surrounding tissue.

Itching can also accompany this type of reaction, but it is not always a primary symptom like redness and swelling. Symptoms such as puffiness and discoloration, flaking and peeling may occur in various skin conditions, but they are not as universally primary indicators of an allergic reaction as redness and swelling are. Understanding the role of these two symptoms is crucial in identifying and managing allergic reactions effectively in a cosmetology context.
