Skin Irritation (topical)

Topical skin irritation manifests as redness, itching, or rash at the application site, usually resolves quickly. It is more prevalent in people with sensitive skin or allergies to ingredients in topical products.

Topical application of certain substances, such as aloe vera, can induce skin irritation in susceptible individuals. Symptoms may include redness, itching, burning, rash, hives (urticaria), and, in severe cases, blistering or swelling. The reaction is often localized to the area of application but can spread in sensitive individuals. The severity and duration of skin irritation can vary greatly depending on factors such as individual sensitivity, concentration of the irritating substance, and duration of exposure. Allergic contact dermatitis, a type of delayed hypersensitivity reaction, is also possible. Ingredients in topical products other than the active component can also be causes of irritation.
