Why do you turn brown when you tan but red when you burn? wot exactly is happening to the melanin??

Answer 1

The brown is your bodies way of making sure that future exposures to the sun are more safe. It is the melanin in your cells spreading out so that the chemical can absorb the light (remember physics class? dark colors absorb light and therefore energy). The red is when you stay in the sun long enough to do damage to your skin cells. The thymidines in your DNA get crosslinked from the UV irradiation and they can't divide properly anymore. The cells end up dying, and a few days later sloughing off in sheets when you peel.

Answer 2

When you get a sunburn this is no different from a regular burn. The skin gets red because it is damaged by the ultraviolet light.

The skin contains special cells called melanocytes which make up maybe 5-10% of skin cells. These cells are capable of producing the skin pigment melanin. It is important to understand that only these melanocytes produce melanin. When the skin is exposed to sunlight these melanocytes are stimulated to begin producing melanin and they then inject this pigment into neighboring cells. The more exposure to sunlight that occurs the more this process is repeated and the skin gets darker as more cells take on more pigment. The melanin in these cells diminishes over time so unless the melanocytes keep get stimulated by sunlight and keep producing melanin the tan will fade.

Answer 3

When you get too much sun, there are two reasons that your skin turns red; especially if you are very fair skinned. The heat of the sun causes blood to flow in capillaries near the surface of the skin (which then looks redder) in an attempt to lose the excess heat. Later the skin may remain or turn red again as blood flows in capillaries near the surface of the skin to help repair damage from too much ultra violate light. The exposure to sunlight triggers the production of more melanin to protect the skin from additional exposure; and you get a lovely tan. There are two basic types of skin that tan. Scandinavian skin is exposed first and tans (develops like film?) later. Mediterranean skin tans immediately upon exposure. The reddening of skin is called erythema

Answer 4

Melanin is produced by your body to prevent your skin from burning. It helps block the UV rays, to a small extent. Burning happens when your skin absorbs the UV rays and it damages the skin itself. More is absorbed faster than your body has the ability to produce melanin. It is the same to your skin as any other type of burn, and the damaged cells react in the same way as they would with any other type of burn.

Answer 5

When you burn, your actual skin is irritated and damaged. This has little to do with the melon in your skin or the pigment. Usually after your skin heals, you will still darken up some, unless the burn was severe in which case several layers of skin will peel off.

Answer 6

in case you have a very vast and open kitchen, then i might say opt for the two partitions purple and 2 partitions tan. in the journey that your kitchen is on the smaller edge, i might basically bypass with one or the different. i'm praying you have darkish brown cabinets by using fact then it would look extremely solid. My clarification for no longer doing the two colorings in a smaller kitchen, it would create a closed in feeling. no count in case you set the darker color on the lengthy aspects and the sunshine on the different ends, or vice versa, you are going to sense like the partitions are coming in on you. Assuming your cabinets are darkish brown, in case you throw some tan on the partitions it extremely is extremely going to make your cabinets pop! then you may herald your reds by accents and upload you're pitcher's and bowls to boot. or much extra desirable, positioned purple vegetation on your pitcher. Or, in case you wanna positioned the purple on your partitions, and your cabinets are darkish brown, you're extremely going to ought to tone down (loosen up) the accents because you have basically created a gloomy room with paint and you opt to stability it out. although, in the journey that your cabinets are white, all my advice will replace.
