One important thing that all patients should be aware of before undergoing laser hair removal is that the skin must be completely healed. If there is any sign of scar formation, it is essential to wait until the wound has healed and the skin has repaired itself. Treatment for scars from laser therapy can include topical or intralesional steroids, silicone gel, or silicone sheets. In some cases, laser rejuvenation may be the best option for a scar, even if it was caused by a laser treatment.

Different lasers can be used depending on the cause of the scar, such as softening a scar, removing abnormal color, or flattening it.

Several treatments may be necessary regardless of the initial therapy. The symptoms of a laser injury include a bright flash of colored light and sometimes a click that coincides with the laser shot.

Laser procedures should be done with extreme caution due to patients' high expectations for optimal results.

The selection of a laser for a specific indication depends on the chromophore of the laser, which is the molecule or molecules most likely to absorb electromagnetic energy of a given wavelength.

Circular hypopigmentation spots may appear after laser hair removal with an alexandrite laser. HSV infections caused by laser procedures must be treated aggressively due to the risk of scarring and bacterial superinfection. Surgeons should selectively choose candidates for laser therapy and not perform elective procedures on patients who are excessively tanned. Laser applications in medicine continue to advance with new devices and expanded indications for laser therapy.

This is a cosmetic procedure that uses intense heat from a laser to damage hair follicles and prevent future hair growth.
