How does the skin protect itself?

Answer 1

UV radiation can penetrate living tissue and damage the DNA in the nucleus of its cells. Our skin has the ability to produce a pigment called melanin that makes it darker (like getting a ten) and then the darker pigment helps stop UV rays from damaging deeper tissues. Too much exposure to UV light can even damage the melanocytes (the cells that produce the melanin pigment) and you can develop skin cancer. The deadliest skin cancer is malignant melanoma and if you suspect that you may have it you should get medical attention right away.

Answer 2

By the epidermis which is the outer layer of skin it protects the new layer of skin that is growing under dead skin cells the dermis which is the inner layer of skin is being protected by the epidermis .Also, it protects the dead skin cells until it builds new skin cells.

Answer 3

The ozone layer reflects most but not all of the ultraviolet rays (UV rays) that the sun radiates. The ozone also reflects some of the heat from the sun. The heat that does permeate the ozone is either absorbed into the earth or reflected off of the earth. This brings up the topic of the "green house effect" which is when the heat that is reflected off the earth itself is trapped within the atmosphere; this is similar to what happens when we wear a jacket.

Answer 4

There is a pigment that our skin produces, called 'melanin' (you've probably heard of it) which has this special role. This protein is created by cells called melanocytes when DNA damage is detected. These melanocytes have a few protruding arms which attach to basal cells, which are particularly susceptible to the harmful effects of UV radiation.

So when our skin is exposed to UV light, such as in sunlight, the DNA in these basal cells may be damaged, causing them to send distress signals to the melanocytes through its attachments, which then results in the melanocyte increasing its production of melanin which it releases into the skin to try to shield these cells from further damage.

Since melanin in humans is a yellow-brown colour, this increased production results in a diffuse pigmentation we know as a tan, or may occur in more localised defined areas such as in freckles and moles.

Remember: A 'holiday tan' is a sign of excess rapid sun exposure, and a symptom of DNA damage. It is the direct result of the skin working incredibly hard to protect the body against harmful UV radiation, the effects of which may damage DNA to the extent that dangerous cancers such as melanoma may occur. Be careful in the sun!

Answer 5

There are thousands of ways to protect your skin from the sun. Few are here

1 Use sunscreen: This is the must-have advice you will get from everyone such as a make-up person, dermatologist, etc. because it is really important. Ultraviolet rays from the sun damage your skin like anything. there are two categories for sun rays UVA and UVB

2 UVA is responsible for wrinkles on the skin

3 UVB is responsible for sunburns

so now imagine how dangerously both can impact your skin

There are good to do things while applying sunscreen on the body such as apply it on the body 15 or 20 minutes early from the exposure to the sun

Try to use at least 30 SPF to protect your screen it blocks around 97% of UV rays apply sunscreen every 2 to 3 hours.

Answer 6

the melin in your body absorbs the suns rays.

Answer 7

With Iron, UV ray armour. You get it from the lvl 60 dungeon, in Stormwind.

Answer 8

The sun protect you skin by melanin which determines the colour of you skin and also helps protect the skin from the damaging rays of the sun.

Answer 9

well, it protects it by blocking the harmful rays, but with too much you may get sunburn or skin cancer
