Phototherapy – a combination of ultraviolet rays is used in many chronic cases. It has a pronounced anti-inflammatory effect on inflamed skin areas.
Appropriate hygiene regimen – the use of soft soaps to protect the skin’s protective barrier as well as the continued use of suitable and maximally non-irritating skin lubricants, adherence to the necessary diet, building habits for sufficient movement, sleep and photo protection.
