Melasma is a common skin condition that causes dark, discolored patches to appear on the skin, most often on the face. While it is not harmful or contagious, melasma can be emotionally distressing for those who experience it.

What is Melasma?

Melasma is a form of hyperpigmentation, which means certain areas of the skin become darker than the surrounding skin. It usually appears as brown or gray-brown patches, most commonly on the cheeks, forehead, bridge of the nose, chin, and upper lip. In some cases, melasma can also occur on other parts of the body, such as the neck or forearms, especially if those areas are frequently exposed to the sun (Bandyopadhyay, 2009).

Though anyone can develop melasma, it is most common among women, especially during pregnancy, which is why it is sometimes referred to as the “mask of pregnancy.” It is also more frequently seen in people with darker skin tones, such as those of Latin American, Asian, Middle Eastern, or Mediterranean descent (Kaufman et al., 2018).

Causes of Melasma

The exact cause of melasma is not completely understood, but several factors are known to contribute to its development.

  1. Sun Exposure: Ultraviolet (UV) rays from the sun are one of the most significant triggers for melasma. UV light stimulates the melanocytes (cells that produce pigment) in the skin, which can cause patches to darken (Grimes, 1995).
  2. Hormonal Changes: Hormones play a big role in melasma. This is why it often appears during pregnancy, with the use of birth control pills, or hormone replacement therapy. These hormonal changes can stimulate pigment production (Sheth & Pandya, 2011).
  3. Genetics: There is a genetic link, as melasma tends to run in families. If a close family member has melasma, one may be more likely to develop it too.
  4. Cosmetic Products and Medications: Certain skin care products or medications that make the skin more sensitive to sunlight can also trigger melasma or make it worse.

Symptoms and Diagnosis

Melasma typically presents as flat patches of darker skin with irregular borders. These patches do not cause any physical symptoms like itching or pain, but they can be distressing from a cosmetic point of view. Dermatologists usually diagnose melasma just by looking at the skin, though in some cases, a special light called a Wood’s lamp might be used to examine the depth of pigmentation (Goldberg, 2008).

Treatment Options

Although melasma can fade on its own especially when it is linked to pregnancy or stopping a medication many people seek treatment to speed up the process. Treatment usually includes a combination of skin care, sun protection, and medical therapies.

  1. Sun Protection: Wearing sunscreen every day is the most important step. A broad-spectrum sunscreen with SPF 30 or higher should be applied, even on cloudy days. Hats and protective clothing can also help.
  2. Topical Creams: Prescription creams that contain hydroquinone, tretinoin, corticosteroids, or a combination of these are commonly used. These ingredients help lighten the dark patches over time (Taylor et al., 2003).
  3. Other Treatments: In some cases, dermatologists might recommend chemical peels, laser therapy, or microneedling. However, these procedures must be done carefully, especially in people with darker skin tones, as they can sometimes worsen pigmentation.
  4. Oral Medications: Recent studies have shown that oral tranexamic acid may help some people with melasma when other treatments do not work. However, this treatment is still under research and should be used with medical supervision (Del Rosario et al., 2018).

Living with Melasma

Melasma can be a long-term condition that comes and goes. It often requires ongoing care and lifestyle changes to manage. Emotional support is also important, as skin conditions can affect self-esteem. Joining support groups or talking to a dermatologist about mental health concerns can be helpful.

Conclusion

While melasma is not dangerous, it can affect a person’s confidence and quality of life. The good news is that with the right care especially sun protection and proper skin treatments melasma can be managed effectively. If you think you have melasma, consult a dermatologist who can help tailor a treatment plan to your needs.
