Lasers are intense beams of light which have been become popular in many different medical fields, including dermatology, surgery, ophthalmology, gynaecology, neurosurgery, ENT, kidney, prostate etc. All these lasers work on special principles formulated by Dr. Taneja’s colleagues in the department of dermatology at the Harvard Medical School and were originally used to treat different conditions of the skin.
The basic idea of medical lasers and similar machines like IPL (Intense Pulsed Light) is to avoid surgeries altogether by using intense focussed beams of light, which very selectively and gently target and heat only the unwanted structures beneath the skin. No pain, harm or damage is caused to surrounding structures or to the superficial skin.
For example, light beams can be adjusted using refined optical physics to selectively target only the unwanted hair roots on a woman’s chin (or any other part of the body) to achieve a smooth hairless face and causing no harm to any surrounding structure. The treatment takes about 5 minutes to perform, is painless and the patient can get back to office or work immediately after the treatment. However, in one session, only about 15%-25% of the roots can be targeted, thus several sessions at monthly intervals are required.
Red-colored vascular birthmarks like hemangiomas or port-wine stains can now be treated very gently and non-surgically by lasers emitting green light which is absorbed by the red color in the blood vessels.
Skin rejuvenation can be achieved with IPL and lasers (“photo-facials”) by improving the skin tone and also by achieving a gentle tightening effect of the skin and this is a good way to maintain a healthy and youthful skin even in normal persons.
Acne scars are a common teenage problem and with proper use of lasers and IPL machines, acne scars can be improved in a series of 10-minute sessions.
Physicians discourage the use of permanent tattoos, but they have unfortunately become commonplace. Unwanted, infected or allergic tattoos can easily be removed with lasers, although tattoos placed deeply with machines and multi-colored tattoos may require many sessions to remove.
Other conditions like moles, wrinkles, pigmentation, different kinds of birth marks, growths, scars, keloids, cancers, vitiligo, psoriasis etc are also easily treated with lasers using light beams of different wavelengths and characteristics.
The main criterion for successful treatment is a qualified dermatologist, who understands and is specially trained in advanced laser physics.
