A sun allergy rash is the skin condition that results due to a hypersensitivity to the hot rays of the sun. This reaction is also known as a Polymorphous Light Eruption (PMLE). The rash most commonly appears during the season of spring when the skin is still in the process of adapting to the change in temperature and heat. The rashes appear within hours after prolonged exposure to sunlight and is only limited to areas of the body which were left uncovered. The rash is self-limiting and gradually improves and eventually disappears once the skin has grown accustomed to the heat of the new season.
Mometasone is classed as a potent topical corticosteroid. Topical corticosteroids are also referred to as topical steroids . Topical steroids are used in addition to moisturisers (emollients) for treating inflammatory skin conditions such as eczema and dermatitis . A topical steroid is used when patches of eczema or dermatitis flare up. Mometasone relieves the symptoms of a flare-up by reducing inflammation, itching and redness. It is not a cure for the condition, but it will help to relieve the symptoms. Short courses of mometasone may also be prescribed for the treatment of psoriasis for small areas such as the scalp, soles of the feet, or palms of the hands.
