Common Mistakes
- Pronouncing it /mɪˈlæn.ɪn/ (incorrect stress).

FAQ
Frequently Asked Questions
No, melanin is found in most organisms, including animals, plants, and even some fungi and bacteria, where it serves various protective roles.
No, the amount of melanin you produce is largely genetically determined. Sun exposure can temporarily increase production (tanning), but not permanently change your genetic baseline.
Eumelanin is brown-black pigment responsible for darker tones. Pheomelanin is a red-yellow pigment found in lighter skin and hair, like red hair and freckles. It provides less UV protection.
Capitalisation (e.g., 'Melanin') is a stylistic choice used on social media to personify, honour, and give agency to the concept, aligning it with cultural pride and movement terminology (similar to 'Black').
