Which of the following is a common sign of an allergic reaction during a skin treatment?

1. Dryness and flakiness

2. Redness, swelling, or itchiness

3. Smooth texture

4. Increased oiliness

The correct answer is: Redness, swelling, or itchiness

A common sign of an allergic reaction during a skin treatment is redness, swelling, or itchiness. These symptoms occur as the body's immune system responds to a substance it identifies as harmful. When the skin reacts to an allergen, the blood vessels expand, leading to redness and swelling, and nerve endings may become activated, resulting in itchiness. Recognizing these symptoms is crucial for safety in cosmetology practices, as they indicate that an adverse reaction is occurring. Timely identification can prevent further irritation and help determine if the treatment should be stopped or modified. This awareness is part of maintaining a safe and effective environment for clients. In contrast, dryness and flakiness may indicate skin damage or dehydration, smooth texture is a sign of healthy skin, and increased oiliness can relate to other skin conditions, but these are not typically linked to allergic reactions. Understanding the specific signs of an allergic response is essential for practice in cosmetology.
