Hi,can someone tell me that patient with eczema need many sessions of cryotherapy to heal molluscum contagiosum bumps?

The success of any treatment session relies on killing the virus within the skin. Treatment makes an effort to avoid a deep wound when the affected area is shed. That means the treatment may not kill all the virus. Also, MC can be present in other skin site not evident during treatment and arise later, resulting in the need for another session.
