How does laser hair removal work?

The hair removal laser emits very short pulses of bright light that are absorbed by pigment in hair.  Laser light energy is converted to heat that damages the growing hair follicle.  The damaged hairs fall out within a week.   Permanent hair removal generally requires several treatments.  Any area of the body can be treated.  Blond, red or gray hairs typically do not respond as well as darker hair. 

How can I get rid of the ugly spider veins on my legs?

Sclerotherapy is still the most effective way to treat superficial blood vessels in the legs.  Tiny needles are used to inject a sclerosing solution that irritates and destroys the bothersome vessels.  Up to 90% of the treated vessels may clear with a single treatment, however, it could take several treatments. Because people who develop spider veins are likely to get more as they age occasional touch up treatments every few years may be necessary to maintain beautiful legs.
