May 6, 2019 Most of the melanin in human skin is eumelanin or pheomelanin. synthesized, it is stored in bodies within melanocytes called melanosomes.

Melanin synthesis and melanosome transport within melanocytes are well characterized. Melanosome biogenesis is divided in four organelle stages [18,20]. There are five basic types of melanin: eumelanin, pheomelanin, neuromelanin, allomelanin and pyomelanin. The most common type is eumelanin, of which there are two types— brown eumelanin and black eumelanin. Pheomelanin is a cysteine-derivative that contains polybenzothiazine portions that are largely responsible for the color of red hair, among other pigmentation.

Melanosomes vs melanin

2013-07-15 · In the skin, there are 2 types of melanin; eumelanin, which is brown-black and photo-protective (meaning it protects you from UVR), and pheomelanin, which is yellow-red and photo-reactive (does not protect agains UVR, and may even be associated with a higher melanoma risk independently of UVR, although that’s not fully understood and far from certain).

On the other hand, Melatonin is the hormone, which is produced by the pineal gland. In 1981 he was General Secretary of the 3rd European Workshop on Melanin Pigmentation and in 1998 he was President of the 8th Meeting of the ESPCR organized in Prague.

The melanin content of B16 melanosomes was more than three times higher than that of HP melanosomes. The content of free and protein-bound DOPA and 5-S-cysteinyldopa varied greatly in B16, HP, and sepia melanosomes and was unrelated to melanin content.

It works by decreasing the production and increasing the breakdown of melanosomes (melanin pigment granules) in the skin's pigment cells (melanocytes).

Cystinosin‐deficient mice also showed a 4‐fold increase in hair pheomelanin content. Conversely, the uptake of melanosomes was found to be independent of PAR-2, suggesting that the use of melanosomes in this assay does not lead to physiological uptake of melanin by keratinocytes.

Pumpkin Fruit Ferment, Papain and Salicylic Acid – These three components Copper to inhibit the Tyrosinase enzyme involved with melanin formation. Niacinamide – This ingredient inhibits the transfer of melanosomes to keratinocytes. Melanocytes insert granules of melanin into specialized cellular vesicles called melanosomes.
