Major Laser Type Therapies

* Ruby lasers (694 nm) that cause lesser epidermal damage.

* The more recent long-pulsed alexandrite lasers that too safeguard the epidermis better

* The strong 800-nm diode lasers are safer for dark skinned people, since the epidermis does not absorb the longer wavelength light that easily.

* Photodynamic therapy is another method that uses laser light and a chemical photosensitizer to damage the hair follicle permanently.

* There are combination packages as well, that are being developed every other day. The topical use of aminolevulinic acid (ALA) is one such additional therapy being considered and studied for use in combination with laser technology. Though in its developmental stage, ALA’s advantages have been identified in its capacity to target larger areas rapidly and its use on more skin types.
