How good is Laser Hair Removal? | Miami Center for Dermatology
Kiss your razor goodbye. Toss the tweezers, Lose the wax.
The primary principle behind laser hair removal is selective photothermolysis (SPTL), the matching of a specific wavelength of light and pulse duration to obtain optimal effect on a targeted tissue with minimal effect on surrounding tissue. Lasers can cause localized damage by selectively heating dark target matter, melanin, in the area that causes hair growth, the follicle, while not heating the rest of the skin. Light is absorbed by dark objects, so laser energy can be absorbed by dark material in the skin, but with much more speed and intensity. This dark target matter, or chromophore, can be naturally-occurring or artificially introduced.
Q. What areas can be treated for hair removal?
A. We can remove hair from most parts of the body, including the face, legs, arms, chest, back and even sensitive areas like underarms or bikini.
Q. What do hair removal treatments feel like?
A. Patients will feel a series of short snaps, somewhat like a rubber band snapping, but no local anesthesia or pain medication is typically required. However, some patients may prefer to use a topical anesthetic when sensitive areas are treated.
Q. How many treatments will I need?
A. Most areas require 5-9 treatments, but the number of treatments you may require for optimal long-term benefits depends on various factors such as hair thickness, the area size, and hair growth cycle. All laser systems work by disabling the hair that is principally in the active growth phase at the time of treatment. Since other hairs will enter this active growth phase at different times, additional treatments will be necessary to disable all of the hair follicles in a given area.
Q. What happens after the treatment?
A. Immediately following your treatment, the area may appear a bit red and tender. Three to seven days after treatment you may experience what seems to be re-growth of hair. Actually, these hairs are being shed as a result of your treatment, and will take approximately 2 weeks to fall out. Between treatments you should not wax or pluck your hair, but you may shave as frequently as you wish.
Q. Is it safe?
A. The beauty of our technology is that it effectively destroys the hair itself without harming the surrounding skin. As with all medical procedures there is a slight risk that will be discussed at your consultation.
Q. Can anyone have it done?
A. No laser or light-based system can treat blonde, white, red or gray hair since there is no melanin to absorb the light.
