The skin disease are a reflection of the inner state of health of an individual, as per homeopathy.
If a person has a healthy immune system then the body repels the infection and literally pushes them outward from the core of the body to the surface, i.e skin.
Homeopathy deals with this issue from centre of body to periphery i.e skin and hence the healing from inside out can cleanse the system and get you free from the skin ailments.
Homeopathic medicine have especially affinity for the skin disorders.
