Can An Increase Or Decrease In Melanin Actually Change Your Skin Color?

Human skin tone varies across the globe. This variation in skin color is attributed to geographical distribution. People who live near the equator have darker skin tone because of extremely high UV radiation. In such regions, the production of melanin pigment increases in the body for protecting the skin from sun rays, which subsequently causes darker complexion. On the other hand, people living close to poles exhibit the lighter-skin tone due to the low intensity of UV radiation.

Despite knowing the biology of skin color, millions of people across the world are obsessed with altering the skin color. Discrimination based on skin color is the vile side of society that is no longer new to anyone. Unfair obsession with fair skin is a strong reason for attaining lighter skin tone. However, many statistics reveal that people with lighter skin tone also feel obligated to have a tan. Racial prejudice not only sabotages one’s self-esteem but also permeates the discontentment and self-loathing in life. 

Fortunately, the latest technology and new interventions in skin care and cosmetic worlds open the doorways for redefining your skin color and texture. Many research studies have claimed that by changing the natural pigment production pathway in skin cells, it is possible to tan or lighten the skin colors.

Role of melanin in the body

Melanin is a pigment in the human body that determines the color of skin, eyes, and hair. This skin pigment is produced by melanocytes in the outermost layer of your skin i.e. epidermis. These are the two main forms of melanin – eumelanin and pheomelanin. Eumelanin makes dark color in skin whereas pheomelanin is responsible for pinkish to red color in the skin. The role of melanin in the skin is to protect it from UV radiation. It acts as a barrier and prevents the UV radiation from penetrating the deepest layers of skin for damaging the DNA and causing skin cancer.
