• #1 avoidance of trigger
• Physical skin protection
• Emollients/Barrier creams
• Topical corticosteroids (TCS) 
• Resistant chronic dermatitis: NB-UVB or PUVA
• Hyperkeratotic palmoplantar dermatitis: acitretin and alitretinoin or systemic immunomodulators (methotrexate, cyclosporine) or biologic therapy

Prognosis

• “Accommodation” or “hardening”: spontaneously resolve even with continuous exposure
• Worse prognosis for resolution: previous history of atopy, female sex, and coexistence of ACD
