Melanin.i think melanin
"What is the role of ACTH and melanin when the skin is exposed to ultraviolet light?"
Melanin gives color to the skin, hair, and iris of the eyes. Levels of melanin depend on race and amount of sunlight exposure. Sun exposure increases melanin production - to protect the skin against harmful ultraviolet rays. In addition, hormonal changes can affect melanin production.
Melanin darkens skin. It is also responsible for photoprotection, ie resistance to ultraviolet light-induced skin damage. This is achieved by rapidly converting incoming ultraviolet light into heat, which is much less likely to cause problems like free radicals. Thus, sunlight exposure tends to stimulate melanin production.
Yes, melanin protects your skin from ultraviolet radiation, which could damage underlying DNA.
No, melanin protects the skin from ultraviolet radiation. Vitamin D is synthesized in the skin and help with calcium absorption.
It is the Melanin.
Melanin is a pigment, a dark colored substance, which protects against ultraviolet radiation; it is produced in skin cells.
Originally, everyone had brown eyes, which are caused by melanin. The melanin protected the eyes from the damaging effects of ultraviolet light.
No, melanin helps protect the skin from ultraviolet damage. Sebum helps protect the skin from dryness.
Melanin, why ? Because melanin acts as a protective biological shield against ultraviolet radiation.
Originally, everyone had brown eyes, which are caused by melanin in the eye. The melanin protects the eyes from the damaging effects of ultraviolet light.
Melanin is a substance produced by the skin that protects the skin from ultraviolet radiation. It also gives skin its color.
Ultraviolet A (long wavelength) initiates production of vitamin D and melanin (tanning). Ultraviolet B (short wavelength) damages the skin causing sunburns and in some cases cancers.
yes melanin pigment effect animals
Originally, everyone had brown eyes. The brown was caused by melanin in the eye. Melanin in the eye protects the eye from the damaging effects of ultraviolet light.
Originally, everyone had brown eyes, which are caused by melanin. The melanin helped protect the eyes from the damaging effects of ultraviolet light.
Yes because their skin has a lot of pigments(melanin).
Yes it helps.
People with high concentrations of the pigment melanin tend to have darker skin.
Melanin is the pigment that gives us our skin tone. The more melanin, the darker one's skin and the more protection from ultraviolet light and the skin cancers that can arise from it.
