eczema can definitely be cured through homoeopathy permanently, but its better to stop those ointments/powders after starting medicines. skin allergies are not much hereditary except very few, but the causes which cause skin diseases to remain inspite of treatment are hereditary, which always remain in the constitution of that particular person.
