One of the most often performed cosmetic procedures is laser hair removal, for many people find hair growth in certain regions of the body unsightly or embarrassing. In other cases, some people wish to lessen shaving, waxing or other methods of hair removal. In laser removal, a laser is used that emits light energy, travelling through the skin and is absorbed by pigment in the hair follicle and shaft. In the laser treatment, light energy is getting absorbed by pigmented areas. Hair follicles in the phase of active growth have the largest amounts of pigment that absorbs laser energy. Hair follicles in other phases, however, are not absorbing the energy, so hair growth is not impaired. Energy and heat from the laser damage the follicle, impairing its ability to produce hair. In time, hairs fall out of the destroyed follicles, resulting in a smooth skin look and less hair production. For optimal results, your hair should be in contrast with the skin. Thus, people with fair complexions and dark hair are optimal candidates.
Before starting the procedure, the doctor can decide to shave the hair in the treatment area. Usually, doctor applies a cooling applicant to the treatment area that helps preventing heat, being generated by the laser, from hurting the skin. Eyewear will also likely be proposed. Time to finish the treatment depends on the area being treated. During the operation, physician moves laser over the required area. Laser delivers light energy through the skin to be absorbed by the follicles that will become destroyed and unable to produce hair. Since hair follicles are not all growing hair at the same time, multiple procedures are likely to be advised. After the treatment, skin can become red and irritated. The redness will dissipate after a couple of days. Doctor can advise using a topical cream as skin protection while it heals.
It’s also important to apply sun protection for several weeks after the procedure. Plucking and waxing of the treated area should also be avoided. It’s important to remember that laser hair removal works differently on different individuals and can’t completely prevent future hair growth. As described minimum six sitting is required for permanent reduction. Patients with hormonal imbalance may require more sitting. Initially the session is repeated at monthly interval and later as and when hair growth is evident. Laser hair removal indirectly improves skin tone and color especially over under arms and private parts. Dr Jayanthy Ravindran received her laser training in Europe and Singapore. Thus she carefully handles lasers suitable for all skin types. The laser that is best suited for Indian skin would be either Diode or NdYAG. Diode is suitable for thin hair on fair skin while NdYAG is suitable for thick hair on Dark Skin. Even though Diode could give better and quicker results the chance of superficial burns are higher with Diode. Dr Jayanthy uses FDA approved machines from the US to perform the procedure of laser hair removal at her facilities in Chennai, which adds to the results and safety.
