Melasma is a common skin condition present in Latin, Asian, black, or native American ethnicities. It is more common in women between 20 and 40 years old, of medium or dark skin tone. It is a common skin concern driven primarily by more active skin melanocytes (cells that produce the skin color). Evidenced primarily by hyperpigmentation in the forehead, upper lips, cheeks, or chin. As you will read, some factors can trigger melasma. But have you wondered if thyroid disorders can be a melasma trigger too?

Autoimmune disorder of the thyroid gland and melasma 


As you know, our thyroid gland has a main function in our body. The thyroid gland is in your neck, and its main function is to produce certain hormones that regulate the body’s main jobs, such as energy production, metabolism, body temperature, and many more. TSH (thyroid-stimulating hormone) is produced by the pituitary gland in the base of the brain, which then triggers the thyroid gland to release Thyroxine (T4) and triiodothyronine (T3), the main hormones of the thyroid gland. 


Melasma and autoimmune disorders both involve a relationship with hormones such as progesterone and estrogen. These hormones are also related to other skin concerns, such as acne. Autoimmune thyroid disorder studies have evidenced that there is an association between thyroid abnormalities and melasma, and this relationship is under continuous study.  Recent studies have shown that hypothyroidism is particularly linked with the development of melasma. This correlation evidence that hormonal imbalances produced particularly by hypothyroidism, can increase melanin production, leading to an increase in melasma cases.


Factors that can trigger melasma


Sun exposure- when we are exposed to the sun, our body reacts like an octopus, producing more melanin as a method of protection. However, this overproduction of melanin can trigger melasma, making it more visible or darker spots. 


Hormones- changes in our hormones in many factors, such as pregnancy, birth control pills.


Medications- anti-seizure medications, sunlight sensitivity medications, antibiotics and some blood pressure medications.


Stress- as you know, high stress levels can have some implications or manifestations in our body, including triggering melanocytes. See here.


Temperature- Specifically, high temperatures can increase melasma response. 

And there are thyroid disorders. 


Possible treatments


Regulating the melanocyte’s activity can significantly reduce the appearance of melasma. Treatments such as chemical peels, lasers, and extremely specific skincare ingredients significantly reduce melasma patches holistically. Therefore, there are several treatments depending on the melasma that can significantly improve the appearance of the skin since the first treatment. 


Key skincare ingredients


Ingredients that regulate the melanocyte’s activity, such as tranexamic acid, retinol, glycolic acid, etc., are some of the skincare ingredients, depending on the skin type and regulated by a professional, that improve melasma. Using guided professional skincare for this type of concern is fundamental because, in many cases, the use of ingredients like hydroquinone without professional guidance and supervision can lead to hypopigmentation, exogenous ochronosis, or simply aggravating the main skin concern.
