Laser
Hair Removal Cape Town, South Africa
|
Your entire body is covered
with hair and that's a fact. But, when
darker, coarser hair appears in places we
don’t like or expect, it may be time to
consider laser hair removal with the Light
Sheer Diode Laser available at Cape Rejuven8
at the Cape Town Medi-spa. This is the gold
standard in hair removal. The laser targets
actively growing hair and destroys the hair
follicle (objective is to target the hair
follicle without causing thermal damage to
surrounding tissues).

That particular hair will then not grow
back. An interval of a minimum of 6 to 8 weeks is required between
treatments to let other hair grow back before your next treatment. Anywhere
between 4 to 8 treatments are necessary to destroy hair follicles resulting
in long-term hair reduction |

Mechanism of action
The primary principle behind laser hair removal is selective
photothermolysis. 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.

Hair
removal lasers selectively target Melanin:
Melanin is considered the primary chromophore for all hair removal
lasers currently on the market. Melanin occurs naturally in the skin (it
gives skin and hair its color). There are two types of melanin in hair:
eumelanin (which gives hair brown or black color) and pheomelanin (which
gives hair blonde or red color). Because of the selective absorption of
photons of laser light, only black or brown hair can be removed.
Both men and women seek laser hair removal services to have superfluous
or unwanted hair removed. Hair removal is commonly done on lip, chin, ear
lobe, shoulders, back, underarm, abdomen, buttocks, pubic area, bikini
lines, thighs, face, neck, chest, arms, legs, hands, and toes.
Laser works best with dark coarse hair. Light skin and dark hair are an
ideal combination, but new lasers are now able to target dark black hair
even in patients with dark skin

Electrolysis is another hair removal method that has been used for over
135 years.[22] It involves treating one hair at a time and is an option
for smaller areas (like eyebrows or upper lip) where precision is
necessary, although even in these areas it has fallen out of favor
because of the possibility of scarring and the pain of the procedure. In
addition it takes so many treatments compared to laser to complete a
large area, and the extreme cost and discomfort are such that
electrolysis is rarely used for large areas. At this time, it is the
only permanent option for very fine and light-colored hair. The FDA
currently allows the term "Permanent Hair Removal" for electrolysis
only. Unlike laser epilation, electrolysis is effective on all hair
