The length of the procedure can be a few minutes, or an hour, depending on the size of the area and begins with your dermatologist applying a thick layer of anesthetic cream about an hour prior to the procedure
A laser produces a beam of highly concentrated light. Different types of lasers produce different colors of light. The color of light produced by a particular laser is the key to its effect on hair follicles.
During the laser hair removal procedure, the light emitted by the laser passes through the skin and gets absorbed by the pigment located in the hair follicles. The laser pulses long enough to vaporize the pigment, disabling several follicles at a time. This results in eliminating or significantly hindering any hair growth in the treated area.
For most patients, multiple sessions are usually needed to optimize results. Typically three or four treatments, six to eight weeks apart, may be needed. However, some patients find significant improvement after one visit, enough to be satisfied with their appearance.
Patients need to wait about a year to see the full effect of the laser hair removal. This is due to the fact that hair growth cycles are about six months. Waiting through two growth cycles would be best in order to see the final results.
Expect some tenderness, swelling and redness following your laser hair treatment. This should only persist for a couple of days, but you should be able to continue your normal routine. In fact you can resume your activities immediately after the procedure. You will be instructed to use moisturizers and to avoid sunlight for up to three weeks.
What are The Long-Term Effects of Laser Hair Removal?
Laser technology has been proven to create a permanent reduction in the number of re-growing hairs following each treatment in most skin types. The number of hair removal treatments required depends on several factors related to your specific kind of hair and skin. Results vary from patient to patient, so please speak with the doctor before the procedure.
