The following information may help to address your question:
The affected skin may smell unpleasant, which may be due to bacteria growing in the rash. If bacterial overgrowth is suspected or there is a lot of crusting, it can be helpful to apply antiseptics or soak in astringents.
Topical medications may include topical retinoids (i.e., adapalene, tazarotene gel, or tretinoin). Topical retinoids may reduce hyperkeratosis within 3 months. However, irritation is a side effect. Other medications may include acitretin, isotretinoin, cyclosporine, or oral retinoids (eg, acitretin, isotretinoin). Oral retinoids have been the most effective medical treatment for Darier disease, leading to reduction of symptoms in 90% of affected people. However, prolonged use is limited due to adverse effects.
Other treatments may include oral antibiotics to clear bacterial infection, oral acyclovir to treat or suppress herpes simplex virus infection; dermabrasion; electrosurgery; and Mohs micrographic surgery for localized areas.
