For dermatological consultations, Teledermatology is used in telemedicine. During a teledermatological session, a dermatologist estimates clinical and laboratory data, makes a diagnosis, and recommends treatment for patients sited at a distance. Eventually, the aim is that a care should be provided to dermatology patients in underserved areas, to look up the excellence of care, and to reduce the cost of care. There are two main types of dermatological consultations.

* Store and forward technology

* Interactive technology

Store and forward technology:

This is more convenient technique due to the fact that there is no require of a consulting physician at the same time as the referring physician and patient. Additionally, compared to the other type, it is also time efficient.

However, this method does have its disadvantages. The consulting physician can not inquire the patient any questions and he can not ask for certain images or close- up images. This can be very challenging because it prevents the consulting physician from making a better diagnosis.

Interactive technology:

The live interactive technology is done live via telemedicine equipment. The major advantage to using this type of technology is that fact that the consulting physician can inquire the patient and referring physician any questions that may be necessary to making a diagnosis and carrying out treatment. Both technologies use two very useful instruments, a dermatoscope and microscope.
