:: Cosmetic Laser Unit
Today the modern medical science is changing according to the needs of the man to fulfill the dreams of their cosmetic and aesthetic appearance. Cosmetology is fast developing with the introduction of newer laser machines. The word LASER is an acronym for Light Amplification by the Stimulated Emission of Radiation
LASER consists of an active medium (crystal, gas, dye) that is raised to an excited state by external energy source such as flash lamp or an electric discharge. The resulting process of stimulated emission in the active medium produces abundance of photons of light all of the same wavelength. A pair of mirrors at each end of the active laser medium reflects the light back and forth on itself to increase the probability of stimulated emission. One of the mirrors allows a small fraction of the light to leak through. The resulting beam of light is the output beam of laser.

The components of the laser
Sunlight is having seven different colours namely Violet, Indigo, Blue, Green, Yellow, Orange, Red with its wave length measures from 400-700 nanometers. Of this 400 nanometer is Violet and 700 nanometer is Red. This visible light is in the center of the electromagnetic spectrum. On the shorter wavelength side is ultraviolet light and then X-rays and gamma rays and cosmic rays on the extremely short end. Infrared light is adjacent to the visible spectrum on the long wavelength side. Microwaves and radio waves have even longer wavelengths. Lasers used for cosmetic laser applications are in the infra red area of electromagnetic spectrum.

Properties of Laser Light
Laser light has three unique properties:
» It is collimated which means it travels in a single direction with very little divergence even over long distances.
» It is monochromatic, consisting of one colour or narrow range of colours.
» It is coherent, which means the entire light waves move in phase together in both space and time ie. Same frequency.

Laser Hair Removal
Laser hair removal, when first introduced in the late 1990’s, was limited to light skinned individuals with dark hair. Efficient laser hair removal was produced initially by Alexandrite and Diode lasers which is useful for Caucasians. Dark skinned individuals could not use these lasers for effective hair removal because early generation lasers were unable to distinguish between skin pigment and hair follicles, which led to the burning of those with darker skin. Today this has all changed. The advent of the new laser line, the Nd YAG has afforded excellent results for individuals with dark skin and dark hair especially for Indians.
In normal circumstances hair production in each follicle occurs in a cyclic fashion, with three main phases – 1. Anagen or growth phase which lasts between two to eight years.
Catagen or transition phase which lasts between two to four weeks. 3. Telogen or resting phase which lasts for two to four months. During laser treatment only active growth phase black hair can be removed. It is advisable to have first three sittings at an interval of 4-6 weeks and next three sittings at an interval of 6-8 weeks period. Later the patient may need 2 or 3 sittings more at an interval of 6 to 8 months period to get maximum result. It is mandatory to find out the causes of hair growth such as Polycystic ovarian syndrome, Hypothyroidism, Congenital adrenal hyperplasia, Cushings syndrome, HAIR AN Syndrome (hyperandrogenism, insulin resistance, acanthosis nigrans), Idiopathic hirsutism, Medications: Phenytoin, Minoxidil, Cyclosporine, Diazoxide or Anabolic Steroids,

Ablative laser procedures
Erbium YAG and Co2 laser machines are used for ablative skin treatments for the lesions like black moles, ageing black spots, skin tags, warts, corns, xanthelasma, acne scar reduction and ablative facial rejuvenation. The selection of the machines depends on the type of skin lesion. The Erbium YAG laser is known to ablate effectively human skin with minimal amount of residual thermal damage. This result in faster reepithelialisation and less pronounced erythema compared with the deeper penetrating Co2 lasers. In clinical laser resurfacing, however coagulation of collagen in the papillary dermis as achieved with Co2 lasers is generally believed to be beneficial because it leads to skin tightening / sculpting and formation of new collagen.

Equipped with advanced Laser machines
Our department of laser cosmetology is having three ranges of laser machines. They are Nd YAG laser ( Neodymium), Erbium YAG laser and Co2 laser machines. Nd YAG laser machine is having wavelength of 1064 nanometers and it is used for removal of unwanted hairs, capillary haemangiomas, warts and non ablative facial rejuvenation. Erbium YAG laser machine is having wavelength of 2940 nanometers and Co2 laser machine is having wavelength of 10600 nanometers. They are used for ablative skin treatments.
