I am not sure about it around your ears.. But as for white spots on your face.. Its not a dangerous medical problem they tend to be more of a nuisance... You may have a allergic reaction to cells that provide pigment in your skin ... It might be dryness of the skin .. Using a good moisturizer will help .. Sometimes doctors would say to use anti-inflammatory creams like hydrocorisone to treat it .. You can check with a dermatologist or another doctor to find out what they really are and get a good reatment
