Eczema in the chronic phase is mainly characterized by roughness, hypertrophy, flaking and more pronounced itching of the skin, in addition to a generally symmetrical distribution. It can be treated with topical glucocorticoid ointment, hard cream, or glucocorticoid cream, together with moisturizers and keratolytic agents, such as urea ointment and 5%-10% salicylic acid ointment. For more sensitive areas such as the face and vulva, calcium-regulated neurophosphatase inhibitors, such as tacrolimus ointment and pimecrolimus cream, can be used, as well as on the folds, which are areas of sensitive skin, and try to use weak, non-hormonal drugs. If itching is obvious, you can take oral anti-allergy and anti-itch medications, such as loratadine and cetirizine tablets, etc. It can also be combined with physical therapy, such as narrow-wave ultraviolet irradiation therapy, etc.
