What is pallor?
Answer:
Pallor is a reduced amount of oxyhemoglobin in skin or mucous membrane, a pale color which can be caused by illness, emotional shock or stress, avoiding excessive exposure to sunlight, anaemia or genetics. It is more evident on the face and palms. It can develop suddenly or gradually, depending on the cause.
Pallor is not usually clinically significant unless it is accompanied by a general pallor (pale lips, tongue, palms, mouth and other regions with mucous membranes). It is distinguished from similar symptoms such as hypopigmentation (loss of skin pigment).
Pale skin is also a very light skin tone most commonly associated with people of European descent, particularly people of Celtic and Scandinavian descent. In addition, people who avoid excessive sun exposure and thus avoid unhealthy sun tanning also tend to have paler complexions in comparison to their peers, particularly during summer.
Skin tone, the way your skin looks.
Basically, it's an unnatural paleness or absence of color ( pigmentation == lack of skin color) in the skin. For example, there is a skin condition called Vitiligo. It is a benign ( not cancerous related ) skin disease of unknown cause that consists of irregular patches of various sizes that lack pigmentation ( very pale/white areas) but, the skin area surrounding these patches can have darkened borders. I hope this answer your question.
