Microirritants

Microirritants are substances that can cause minor irritation to the skin or other tissues. They are often present in everyday products and are typically found in low concentrations. The term "microirritant" implies that the irritant is present in small quantities or has a mild effect, as opposed to a strong irritant that would cause immediate and noticeable damage.

Common sources of microirritants include soaps, detergents, fragrances, preservatives, and certain fabrics. These substances can disrupt the skin's natural barrier function, leading to dryness, redness, itching, or a stinging sensation, particularly in individuals with sensitive skin. The reaction is usually not severe and may be temporary.

The effect of microirritants can be cumulative. Repeated exposure, even to low concentrations, can lead to a buildup of inflammation and increased skin sensitivity over time. This can make the skin more prone to reactions from other environmental factors or allergens. Understanding the presence of microirritants in personal care products and household items can help individuals with sensitive skin make informed choices to minimize potential irritation. Identifying and avoiding specific triggers is often a key strategy for managing skin sensitivity.
