A study published in the Journal of Investigative Dermatology found that hormonal changes, particularly in women during pregnancy or while taking birth control pills, can contribute to the development of brown spots on the face. These hormonal fluctuations can stimulate the production of melanin, leading to increased pigmentation.
Genetics can also play a role in the formation of brown spots. Research suggests that certain genetic variations, such as those related to melanin production and distribution, can increase the likelihood of developing hyperpigmentation, including brown spots, on the face.
