Health reasons that cause melasma on face

Melasma, a condition marked by brown or light brown patches on the face, neck, shoulders, and hands. While it looks like brown patches on skin that most people mistake for sunburns, there may be many underlying health reasons that might cause it. Here are some of them:

Hormonal Factors

Hormonal changes play a significant role in melasma development. This is why it's often called the "mask of pregnancy" as it commonly affects pregnant women. Fluctuations in hormones like estrogen and progesterone can trigger melanocytes (cells responsible for skin pigmentation) to produce more melanin, leading to the characteristic brown patches. Hormonal medications such as birth control pills or hormone replacement therapy can also contribute to melasma.

Sun Exposure

According to Ritu Khariyan, cosmetologist, Skinlogics, "The sun is a major trigger for melasma. Ultraviolet (UV) rays from the sun stimulate melanocytes, causing them to produce more melanin. This is why melasma often worsens during summer or in sunny climates. It's not just UVB rays that are problematic; UVA rays and even visible light can also contribute to melasma. This makes protection against sun exposure crucial for managing melasma."


Apart from UV radiation, heat itself can exacerbate melasma. Prolonged exposure to high temperatures, such as during hot weather or activities that cause sweating, can worsen existing melasma or trigger its development.

Visible Light

Studies suggest that visible light, including blue light from electronic devices, can also play a role in melasma. This is an emerging area of research, and while more studies are needed, it's important to be aware of the potential impact of visible light on skin pigmentation disorders like melasma.

Genetic Predisposition

There is evidence to suggest that genetics may also contribute to melasma. People with a family history of melasma are more likely to develop the condition themselves.

Home remedies to treat melasma

Here are some home remedies that may help in managing melasma:

Lemon Juice

Lemon juice contains citric acid, which has natural bleaching properties that may help lighten dark spots. Squeeze fresh lemon juice and apply it directly to the affected areas using a cotton ball. Leave it on for about 10-15 minutes and then rinse with lukewarm water. Repeat this process daily for several weeks to see improvement.

Aloe Vera

Aloe vera has soothing and skin-lightening properties, making it beneficial for treating melasma. Extract fresh aloe vera gel from the leaf and apply it to the affected areas. Leave it on for 20-30 minutes before rinsing with water. Repeat this remedy twice daily for noticeable results.

Apple Cider Vinegar Toner

Apple cider vinegar (ACV) has natural acids that can help exfoliate the skin and lighten dark spots. Dilute ACV with water in equal parts to create a toner. Apply the toner to the affected areas using a cotton pad and leave it on for a few minutes. Rinse off with water and moisturize afterward. Use this toner once daily, preferably in the evening, and follow up with sunscreen during the day.

Sun Protection

One of the most crucial aspects of managing melasma is sun protection. Always wear a broad-spectrum sunscreen with SPF 30 or higher, even on cloudy days. Reapply sunscreen every 2 hours, especially if you're outdoors or swimming. Wear wide-brimmed hats, sunglasses, and protective clothing to shield your skin from harmful UV rays.
