New Generation Lasers & Leading Edge Treatments With CANDELA Technology

A laser workshop was taken place in Gerbera Room, Mulia Hotel, Jakarta, Indonesia on February 28, 2007. There were 2 speakers: Taro Kondo, MD (Tokyo Women Medical University) and Aryani Sudharmono, MD (Division of Aesthetic Dermatology, Dept. of Dermatology and Venereal Diseases, Faculty of Medicine, University of Indonesia).

Taro Kondo talked about “Gentle YAG Treatment in Hair Removal ,Vascular Lesions and Skin Rejuvenation” while Aryani Sudharmono presented “V Beam Experiences in Indonesia”. As an addition to the speakers’ presentations, a live demo was presented by Taro Kondo for Gentle YAG and V Beam Perfecta.

Overall, this meeting was a great opportunity both for doctors and investors. The market is growing even greater and faster with the raising demand and better understanding of individual health as well as the interest to beauty and wellness.

Many doctors are interested in Laser Medicine and Surgery. Recent data shows that more than 400 doctors are now registered as members of The Indonesian Society for Laser Medicine. Training and education are most important and highly critical in the competency development programs in laser medicine.

Let me quote some basic principles on the selective photothermolysis as written by Yacov Domankevitz, a senior scientist at Candela Corporation:

Laser treatment of vascular lesions is based on the principle of selective photothermolysis (Parrish and Anderson). By proper selection of laser system parameters, selective heating of vessels within the skin is possible while producing only minimal damage to the overlying epidermis and adjacent dermis.

The basic elements of selective photothermolysis for the treatment of vascular anomalies are:

1. Selective Absorption -- Laser energy should be preferentially absorbed by blood vessels and not by the overlying epidermis and adjacent dermis.

2. Optical Penetration Depth (OPD) -- Laser energy should penetrate sufficiently deep to reach the larger and deeper situated vessels.

3. Energy Deposition -- Laser energy at the vessel site should be sufficient to heat the vessels to the damaging temperature.

4. Damage Confinement -- The exposure time of the laser energy should be less or equal to the thermal relaxation time of the vessels

5. Epidermal Cooling -- Although this is not a basic element of selective

photothermolysis it is an essential element in many laser therapies.
