People with dark skin, since increased melanin levels in the skin reduce natural production of vitamin D3. Older adults—our skin’s ability to naturally produce vitamin D3 decreases with age.
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. [ 41 ] Microphthalmia-associated transcription factor (MITF) is the master transcription factor that controls the expression of TYR, TRP1, and TRP2, MART1 ...
Melanin (/ ˈ m ɛ l ə n ɪ n / ⓘ; from Ancient Greek μέλας (mélas) 'black, dark') is a family of biomolecules organized as oligomers or polymers, which among other functions provide the pigments of many organisms. [1] Melanin pigments are produced in a specialized group of cells known as melanocytes.
Vitiligo is a skin disease where people lack melanin in certain areas in the skin. People with oculocutaneous albinism typically have a very low level of melanin production. Albinism is often but not always related to the TYR gene coding the tyrosinase enzyme. Tyrosinase is required for melanocytes to produce melanin from the amino acid ...

Melanin is produced in specialized cells called melanocytes, which are found in the lowest level of the epidermis. [85] Melanin is produced inside small membrane-bound packages called melanosomes. Humans with naturally occurring light skin have varied amounts of smaller and sparsely distributed eumelanin and its lighter-coloured relative ...
Natural bronzers use natural ingredients, such as caramel, riboflavin, etc. These ingredients provide a slight instant boost of color, but will wash off in the shower. Higher quality natural bronzer lotions will have certain organic ingredients/natural or exotic extracts that aid in the process of tanning (melanin production/oxidization).
