The colour of one's skin is determined by melanin that is made by special skin cells. Melanin gives the skin its colour without which our skin would be pale pink. Skin pigmentation is dependent on the amount of melanin that is being produced. Skin pigmentation conditions may plague many people when there is an imbalance in the melanin production within the skin, due to damage to these melanin producing cells. Let us find out more about these conditions-
If there is too much melanin production in the body, the skin may give a dark hue or show up as patches of discolouration. On the other hand, if the melanin production is too low, then the skin may give light or white coloured patches.
The awry skin pigmentation can give rise to a number of conditions with depigmentation, hypopigmentation or hyperpigmentation. Albinism is a genetic skin condition giving rise to almost no colour. An abnormally low amount of pigmentation can create hypopigmentation, making the skin look much lighter than it actually is.
Finally, hyperpigmentation is a condition where there is increased pigmentation, either due to increased melanin production or due to other pigment creating substances in the skin. In such cases, the skin appears darker in colour than its original shade.
Dermatoscopy and woods lamp examination can help in understanding the cause of the pigmentation problem. Also, sometimes blood tests may be required for diagnosis.
The treatment of hyperpigmentation is done by the use of skin lightening preparations. Procedures like chemical peels, microdermabrasion and laser therapy can be done which target the top layer of the skin. If you wish to discuss about any specific problem, you can consult a Dermatologist.
