Liver Spots

• Liver spots and solar lentigines are spots that
  can be flat tan, brown or black. They
  differentiate in size and are generally seen on
  the face, hands, shoulders and arms, areas that
  are most exposed to the sun.Liver spots are
  very common in adults who are older than age 50.
  But, younger people can get them too, especially
  if they spend a lot of time in the sun.For
  cosmetic reasons, liver spots can be lightened
  with skin-bleaching products or extracted.
  Although, preventing liver spots can be done by
  avoiding the sun and use of sunscreen will be the
  easiest way to maintain your skin's youthful
  appearance.

Causes of liver spots

• Liver spots are primarily caused by years of
  exposure to ultraviolet (UV) light from the sun.
  The use of commercial tanning lamps and tanning
  beds can also contribute to the development of
  liver spots.The pigment in the upper layer of
  skin (epidermis) that gives your skin its normal
  color is called melanin. UV light increases the
  production of melanin, creating a tan that helps
  in protecting deeper layers of skin from UV
  rays.On areas of the skin that have years of
  frequent and prolonged sun exposure, age spots
  appear when melanin becomes "clumped" or is
  produced in particularly high concentrations.

Risk factors related with liver spots

• Although liver spots can be developed in anyone,
  you may be more likely to develop the condition
  if you
• Have light-colored or fair skin
• Have a history of frequent or intense sun
  exposure or sunburn

Prevention

• To help avoid liver spots, follow these tips for
  limiting your sun exposure
• Avoid the sun between 10 a.m. and 3 p.m. As the
  sun's rays are most intense during this time, try
  to schedule outdoor activities for other times of
  the day.
• Use sunscreen - 15 to 30 minutes before going
  outdoors, apply a broad-spectrum sunscreen that
  provides protection from both UVA and UVB light.
  Use a sunscreen with a sun-protection factor
  (SPF) of at least 30. Apply sunscreen generously,
  and reapply every two hours or more often if
  you're swimming or perspiring.
• Cover up - For protection from the sun, wear a
  broad-brimmed hat, which provides more protection
  than does a baseball cap or golf visor, and
  tightly woven clothing that covers your arms and
  legs. You might also consider wearing clothing
  designed to provide sun protection. An
  ultraviolet protection factor (UPF) of 40 to 50
  provides the best protection.

Symptoms of liver spots

• Typically, liver spots develop in people who are
  having a fair complexion, but they can be found
  in those with darker skin. Liver spots
• Are flat, oval areas of increased pigmentation
• Are usually tan, brown or black
• Occur on skin that has had the most sun exposure
  over the years, like the backs of hands, tops of
  feet, face, shoulders and upper back
• Liver spots can vary from freckle size to more
  than 1/2 inch across and can group together,
  making them more prominent.
