  Skin lightening creams contain various compounds including mercury , steroids and hydroquinone.
  
  These compounds have various side effects(harmful effects ) including itchy skin, burning or tingling sensation ,kidney and liver damage , abnormalities in a new born baby (if used during pregnancy).
  
  Mercury is especially harmful as it may cause sleeplessness, headaches , abnormal sensations , muscle twitches , shaking , weakness , weakening of muscles, reduced cognitive functions, kidney problems and may even cause neurological problems in an unborn children.
  
  It would be advisable to not use skin lightening creams
