Several skin whitening agents, including tyrosinase inhibitors, have been found to cause an increase in the expression of tyrosinase, which by itself would increase melanin synthesis. [ 43 ] Microphthalmia-associated transcription factor (MITF) is the master transcription factor that controls the expression of TYR, TRP1, and TRP2, MART1 ...
Melanosomes, which are organelles containing melanin, must be transported and increased during hyperpigmentation and tanning, while they shrink during hypopigmentation. [4] Skin pigmentation is frequently caused by sun exposure. To protect itself against UV radiation from the sun, the body makes more melanin. As a result, the skin may become ...
It is caused by melanocyte or melanin depletion, or a decrease in the amino acid tyrosine, which is used by melanocytes to make melanin. [2] Some common genetic causes include mutations in the tyrosinase gene or OCA2 gene. [3] [4] As melanin pigments tend to be in the skin, eye, and hair, these are the commonly affected areas in those with ...
Melanin is what gives your hair and skin its color. As you age, you produce less melanin, resulting in gradual graying. Genetics will affect when this starts, but generally speaking, most people ...
Melanin is brown, non-refractile, and finely granular with individual granules having a diameter of less than 800 nanometers. This differentiates melanin from common blood breakdown pigments, which are larger, chunky, and refractile, and range in color from green to yellow or red-brown. In heavily pigmented lesions, dense aggregates of melanin ...
