Does changing your natural skin characteristics by accident or by choice affect the synthesis of vitamin D3 by my skin? Scar tissues, moles, freckles, aren't the same as regular skin, but natural. Tattoos on the other hand are self inflicted permanence. If someone gets a large piece of work that covers large areas of the body, will that affect vitamin D synthesis positively, negatively or neutral. Tattoos, heat up hotter than the rest of the skin, and consequently hurt like a muthah when you get sunburnt; but does this increases the synthesis, or inhibit it?
Has there been any research on this topic?
Addendum: Does someone with large pieces of ink or scars need to supplement D3?

Vitamin d is formed at the outer most surface of the skin and not deep layers of the epidermis.

Note, not a doctor, and don't play one on TV. However, my recollection is that Vitamin D is generated in the lowermost layers of the epidermis, and tattoos are in the dermis under that. So logically speaking, tattoos shouldn't block the UV that generates the vitamin D. The heating up you are getting indicates that there's more absorbtion of the rays though. Whether the heat and that interaction help/hinder D creation, I don't know (I'm assuming Dr K's info is better than mine on the real interaction being negative).
Scars are on the epidermis, but whether or not they impact Vitamin D generation to any extent, I don't know. I can see it if you've got extensive scarring, but it'd probably depend on degree.
Overall question though is vitamin D creation/supplementation. The reality is a huge number of people don't get enough vitamin D as it is. I suspect it's really a moot point since most people need to supplement, and you don't really know without blood tests.
