Evenness of colour

Posted on 25 May 2011

The colour of skin has been responsible for so many events in history that most people never seem to get beyond it. It may also be that cause of personal trauma for many of us. Colour of the skin is predominantly determind by one pigment meline. We are all born with a certain quantity of melanin in our skin. This is called our constitutive pigmentation and would remain the same throughout our lives if we never exposed ourselves to the sun.

What our skin colour turns into after sun exposure is called facultative pigmentation. Depending on how our skin is affected by the sun, or our skin photo type, we either burn or tan. It is the after effects of this exposure that leads to unevenness or blotchiness on the skin.
The most desirable quality in skin colour is evenness to have one single colour or tone. Whatever our skin colour, if it were all one single tone, the skin would look great. The peoblem, really, is patchiness. When certain parts of the face are darker and other parts lighter, it leads to a patchy appearance. This is furthur complicated by the circulation of blood and distribution of blood vessels on the face. This is balence the blood contains another pigment caleed haemoglobin which adds to the patchiness and unevenness of colour.
Moreover, all the diseas which cause inflammation, like pimples, boils, allergis, sun burn, etc. can potentially cause pigmentation on the face. They can make the skin look lighter(hypo pigmentation) or darker(hyper pigmentation). Both conditions are undesirable as they play a major role in detracting from the glow on the

face.

The main reason for this that varying levels of pigment reflect light in dieerent ways and with different intensities. Hence, the object being visualized i.e. thw face, looks dull and seems lacking in sheen and radiance.
Also, we Indians a whole have more melanin on our skin than many other races. This is actually our armour against the sun and protect us from sun induced skin cancers. However, this in turn causes us to produce pigment more easily than lighter skin types. often leading to an uneven, blotchy appearance.
Two other important causes of hyper pigmentation are hormones and aging. In women, hormones may cause a special kind of pigmentation called melasma, which appears like a dark mask on the cheeks, forehead, chin, and nose. This occurs for the first time either during pregnancy or when you are in your mid thirties and needs expert advise and treatment.
CONTRIBUTING FACTORS
  • Regular sun protection
  • Good texture of skin
  • Absence of skin disease
  • Good blood supply
Aging usually called photo aging, causes dark spots on the skin, usually due to excessive sun exposure. This manifests on the face as freckles, small dots of hyper pigmentation like the ones you see on comic book hero Archie’s face, or as dark clumped up growths caleed keratosis or seborrhic warts which can be seen and felt as raised elevations.
Hypo pigmintation or the lightening of skin is caused by inflammations in the form of boils; due to various skin allergies; leucoderma, a skin disease; or simply due to age.
