Redness or swelling is a classic indicator of an allergic reaction. When the skin comes into contact with a substance that the immune system perceives as a threat, it can trigger an inflammatory response. This response often manifests as redness due to increased blood flow to the area and swelling as the body sends white blood cells and other fluids to address the perceived threat.

Such reactions can vary in intensity, and while mild cases may involve slight swelling or redness, more severe allergic responses can lead to significant irritation and discomfort. Monitoring for these signs is crucial in a cosmetic context, as timely identification of an allergic reaction can help prevent worsening symptoms and allow for appropriate intervention.

In contrast, other options such as dry skin without irritation, slight itching, and a healthy glow do not typically indicate an allergic reaction. Dry skin may suggest dehydration or lack of moisture rather than an allergic response, while slight itching could be attributed to other factors like dryness or sensitivity, and a healthy glow is usually associated with well-hydrated, cared-for skin that does not indicate any irritation or allergic response.
