یہ جلد کی رنگت تبدیل ہونے کی بیماری ہے جو کہ سورج کی روشنی کا سامنا کرنے کے باعث سامنے آتی ہے۔ میلازما سے زیادہ تر ماتھے، گال، ہونثوں کا اوپری حصہ اور ٹھوڑی کی جلد متاثر ہوتی ہے۔ لیکن یہ سورج کا سامنا کرنے والے دیگر اعضا پر بھی اثر انداز ہو سکتا ہے۔ یہ جلد پر گہری رنگت کے دھبوں کی صورت میں ظاہر ہوسکتی ہے جو الگ الگ بھی ہو سکتے یا بہت سے دھبے مل کر ایک بڑا دھبہ بنا سکتے ہیں۔ ماہرین میلازما کو سورج کی روشنی اور جسم میں ہونے والی ہارمونل تبدیلیوں کا خمیازہ گردانتے ہیں۔ حمل کے دوران یا ہارمون ریپلیسمنٹ تھراپی کی وجہ سے میلازما کا سامنا کرنا پڑ سکتا ہے۔ اگرچہ یہ بیماری کسی تکلیف کا باعث نہیں بنتی لیکن کاسمیٹک مسائل نمودار ہو سکتے ہیں۔ اس کے علاج کے لیے خاص قسم کی کریموں کا استعمال کروایا جاتا ہے جس کے ساتھ ساتھ سورج کی روشنی سے بچنا انتہائی اہم ہے۔
Melasma is a pigmentation disorder that involves sun-exposed skin areas. This condition appears as overly pigmented spots on the skin. These spots could merge with each other or could appear dotted all around. These spots appear on skin areas that are frequently exposed to the sun. The most common places are the cheeks, chin, upper lip and forhead; nevertheless, they might appear on other sun-exposed areas. Doctors have associated melasma to exposure to the sun, hormone administrations and changes like that experienced in Hormone Replacement Therapy and pregnancy. The majority of the people who have melasma also have a history of overexposure to sun. However, researchers suspect that heat might also be a factor. Melasma cream could be used to treat this condition. Melasma is treated with a certain melasma cream.
Melasma basically is characterized by discolored skin patches that are darker than the surrounding skin. It normally affects the face and occurs in a matching pattern on both sides. However, it can also occur on other body areas that are also exposed to the sun.
These patches typically manifest on these areas on the face:
The neck and forearms can also be affected by melasma. The discoloration does not itself cause any serious pain or harm. However, it can have negative psychological consequences, especially on the person’s self-esteem and body image.
In the winter, the pigmentation in melasma tends regress. Experts have suggest various factors; however, it is not completely certain that these are the only variables cause melasma. Research reveals several aspects including pregnancy, birth control pills, HRT, genetic history, race and certain medications, to play partial roles in the development of melasma. Nevertheless, the most significant factor that has a lot of research support is too much exposure to the sun paired with genetic predisposition. An observation that supports this is that melasma usually develops in the summer season when exposure to intense sunlight is more likely. The condition then regresses during the winter season.
The risk factors mirror the causal factors. The genetic component puts the individual at a higher risk of getting malesma; about 4 in every 10 people with this condition have one affected relative. Exposure to too much UV radiation along with hormonal fluctuation in hormone therapies and/or pregnancy qualify as risk factors. Furthermore, experts have identified phototoxic drugs, chemicals, cosmetics and steroids as important factors as well. People who are more prone to anxiety and stress are also at a higher risk of developing malasma; this has caused scientists to think that stress is actually an important factor.
Measures to prevent melasma largely involve restricting sun exposure. Even then, the person cannot totally prevent melasma. Those who already have it in their family should be especially cautious.
Limiting sun exposure is the best preventive measure there is for melasma. If sun exposure is unavoidable or inevitable, the person could wear materials that could block sunlight as much as feasible. These materials include sunscreen, sunglasses and hats.
There are currently four melasma types, based on their pigmentation patterns:
