• Emotional stress: Disorders related to thyroid gland disorders may be one of the contributors to the appearance of melasma.

Knowledge of these factors aid the management of the disease and forms the basis of the treatment approach.

Hormonal Influences and Genetic Predisposition

The female sexual hormones mainly estrogen and progesterone play a significant part in the development of melasma. However, the condition has also been associated with those women who use estrogen-containing contraceptives. This condition is quite common in females of reproductive age.

Certain genetic profiles may be responsible for the tinging appearance of some individuals known as melasma. Studies indicate that: 

There is an increased risk of developing the condition in people with a family history of it. 

Genetic variations in skin color genes may be involved. Ethnic group is another of the factors.

Fitzpatrick skin types III through VI have a higher rate in this incidence therefore there are hormonal factors and genetics that play a big role in the development of melasma.

Effect of UV Exposure and Environmental Triggers.

Ultraviolet (UV) exposure is one of the commonest aggravating factors as well as contributory in the etiopathogenetic of melasma.

UV rays lead to stimulation of melanocytes accompanied by the production of more melanin. Also, environmental factors like pollution, heat, and visible light are some of the common factors that worsen the melasma.

Key Factors:

• UV Radiation: Long-term exposure to sunlight often results in stimulating melanin cells leading to overactive melanocytes.
• Heat: Elevated temperatures enhance concentrations of melanocytes.
• Pollution: Pollution has some effects on human bodies and there are some pollutants that have systematic toxicities that can cause skin oxidative stress.
• Visible Light: The blue light emitted from TVs and other sources can lead to melasma. It is very important to know these triggers so that appropriate management of melasma can be done from its prevention to its treatment.

Symptoms and Diagnosis of Melasma

The most common presentation of melasma is as dark, irregular, shaped skin spots or patches and is most common on sun-exposed areas:

Common symptoms:

• Areas with brownish, tan, or blue-grey tones
• Evenness of skin color even from cheekbone to chin area
• Usually develops on the forehead, cheeks, nose, and chin
• Can extend out to the collarbone and the back of the hands

Diagnosis:

1. Visual Inspection: The most important characteristic of the condition that makes it visible to the naked eye is observed in most cases of melasma in women.
2. Wood’s Lamp Examination: A UV lamp is used to do this test which brings depth of the pigmentation.

• Hydroquinone: It is one of the most common skin-lightening agents using contemporary medicine. This drug works through an inhibitory effect on the enzyme tyrosinase that is key in melanin synthesis.

• Corticosteroids: Corticosteroids are also used in the treatment of skin disorders and are frequently used together with other medicines of the other active poultices which relieve inflammation and irritation.
