Question: 1 / 400

What indicates a possible allergic reaction in skin treatments?

Increased hydration

Redness, swelling, or itchiness

Redness, swelling, or itchiness are classic signs of an allergic reaction, particularly in the context of skin treatments. When the skin is exposed to certain products or ingredients, the immune system may respond with inflammation, leading to these symptoms. This reaction is often due to irritation from potential allergens, which the body identifies as harmful substances.

Recognizing these symptoms is crucial for both the practitioner and the client, as it can inform necessary changes to the treatment regimen or ingredient selection. While increased hydration, enhanced skin elasticity, and a smoother skin surface may indicate that a treatment is effective or beneficial, they do not signal an allergic response. It’s essential to differentiate between positive treatment outcomes and adverse reactions, as the latter requires immediate attention to prevent further complications.
