MELASMA / CHLOASMA

Skin Health
Melasma1

 

  • A common skin condition of hypermelanosis that typically occurs on sun-exposed areas of the face.
  • Triggering factors include the use of birth control pills, estrogen replacement therapy, mild ovarian and thyroid conditions, ovarian tumors, cosmetics, nutrition, phototoxic / photoallergic medications and medications for epilepsy.
  • The pathogenesis is poorly understood, but genetic and hormonal influences in combination with UV radiation are important.
  • Melasma is rarely reported before puberty and is far more common in women aged 20-50, (reproductive age group) and often begins or is exacerbated during pregnancy.
  • People with darker skin types are more frequently affected.

Clinical Features:

 

  • The lesions are brownish macules with irregular borders and symmetric, photodistribution usually on the face.
  • Sun exposure intensifies the lesions.
  • There are three major patterns of distribution of the lesions:
    • (1) centrofacial (63%: forehead, nose, chin, and upper lip)
    • (2) malar (21%: nose and cheeks), and
    • (3) mandibular (16%: ramus mandibulae)
  • The anterior chest and dorsal forearms may also be affected.

Management and Prevention:

  • Sun protection is central to management.
  • Hypopigmenting agents such as hydroquinone, tretinoin, salicylic, and kojic acid are helpful when used for prolonged periods.
  • Chemical peels and laser therapy may be helpful in the treatment of melasma.
  • The frequent use of sunscreens, either chemical (topically applied on the face) or physical (hats and umbrellas) are helpful to prevent further progression of melasma lesions.
  • For further information and questions, consult a dermatologist certified by the Philippine Dermatological Society (PDS), the true experts on skin, hair and nails.

MELASMA (Pekas o Mantsa) 

  • Ay isang karaniwang kundisyon sa balat kung saan may pangingitim sa mga lugar na naaarawan tulad nang mukha partikular ang pisngi at noo.
  • Ang mga maaaring sanhi ng paglitaw nang kundisyong ito ay ang pag-inom ng birth-control pills, pagbubuntis, sakit sa thyroid at obaryo, pag-gamit ng kosmetics at mga gamot lalo na sa epilepsy.
  • Wala pang siguradong sanhi ng paglitaw ng mga pekas sa isang tao ngunit, may relasyon itong hormonal at genetic at may relasyon sa ultraviolet radiation ng araw.
  • Ito ay mas karaniwang nakikita sa mga taong kayumanggi ang kulay ng balat (tulad nating mga Pilipino) at sa mga kababaihang edad 20 – 50 taong gulang.

 

Sintomas: 

  • Ito ay mga patse o mantsa na may iregular na border at lumilitaw sa mga naa-arawang bahagi ng katawan lalo na sa mukha.
  • Ang madalas na pagpapa-araw ay nakalalala sa kundisyong ito.
  • Kalimitan, may tatlo itong pattern:
    • Sa gitna ng mukha (63% noo, ilong, ibabaw ng labi, baba)
    • Sa magkabilang pisngi (21%)
    • Maaari rin sa panga (16%)
  • Minsan, ito ay lumalabas din sa braso at dibdib.

 

Gamutan at Paraan ng Pag-Iwas 

  • Ang pag-iwas sa matinding init ng araw ang pinaka-mahalagang paraan upang maiwasan ang paglitaw at pagdami ng pekas.
  • May mga maaaring ipahid na gamot pampaputi tulad ng hydroquinone, tretinoin, at mga produktong may salicylic at kojic acid.
  • Ito rin ay nagagamot ng kemikal peel at laser.
  • Ang kalimitang paggamit ng “sunscreen,” na maaaring pinapahid sa mukha (kemikal sunscreen) o ang paggamit ng payong at sumbrero (pisikal sunscreen) ay makakatulong maka-iwas sa pagkakaroon ng pekas.
  • Para sa mga katanungan, kumonsulta lamang sa dermatologist na sertipikado ng Philippine Dermatological Society o PDS na mga eksperto sa kundisyon ng ating balat, buhok at kuko.
