Description of Anti-irritant: anti-irritants are substances that reduce irritation of the skin. Similar, to Anti-inflammatories, these additives provide a soothing effect to the skin and reduce redness and irritation. The difference between Anti-irritants and Anti-inflammatory agents is that the latter actively reduces inflammation in the skin, whereas the first prevents irritating particles from interacting with the skin, and thus preventing and getting rid of irritating effects.
In the Personal Care industry, Anti-irritants are added to some Skin Care products in order to give a soothing effect and reduce redness and irritation of the skin. An ingredient such as Allantoin is known for its soothing and anti-irritant properties.
