Dead skin cells absorb almost all UVC so it does no damage.

Why doesn't uvc reach us?
UVC is entirely absorbed by dead skin cells and is not dangerous. UVC may be a problem on broken skin and if shone direct into the eyes for long periods but as a general killer of virus and bacteria it is very useful. There are no known links between UVC and cancers and by killing virus's it may prevent you getting virus induced cancers.
What electromagnetic waves must sunscreen protect the skin?
UVa and UVb are considered beneficial to the skin as they are responsible for the production of Vitamin D and certain anti-cancer processes. UVc is considered carcinogenic and therefore anything above that is as well.
Is uv radiation harmful?
UV radiation is very harmful in many ways, first off they are invisible rays that come from the sun, UV radiation is made of ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). These rays burn skin and cause cancer. UVB and UVC penetrate the ozone layer. UVA and UVB cause skin cancer, for this reason, sunscreens are recommended that block UVA and UVB.
What does production plan mean?

How the sun as radiation sources?
The sun has 3 types of wavelengths. UVA (315-400 nm), UVB (280-325 nm), and UVC (180-280). UVA wavelenghts is the type which is the biggest cause of sunburn, skin aging, eye damage, and may even affect immune systems. UVB wavelengths on the other hand are the type more responsible for skin cancers. Only the last, UVC is the least harmful of all as much of it is blocked by the ozone layer and absorbed into the environment before it reaches us.The majority of UV radiation is between 10 and 4. UV radiation is so powerful that you can become sunburned on cloudy days.
What is the definition of the word UVC?
There are two definitions for UVC. One being radiation in the ultraviolet spectrum and is more hazardous than UVB. The second is medical which has essentially the same meaning.
Which part of the em spectrum can be used to kill bacteria?
Ultraviolet (UV) radiation, specifically UVC light, can be used to kill bacteria. UVC light has a short wavelength and high energy, which damages the DNA and RNA of bacteria, preventing their growth and reproduction. This property makes UVC light an effective tool for disinfection purposes.
Which conditions affect all layers of the skin?

Which light rays can cause skin damage similar to sunburn?
There are three types of rays- UVA, UVB and UVC. UVB and UVA act differently upon our skin and do not equally damage it. The UVB rays are mostly responsible for most cases of sunburn, as they are shorter than UVA rays. The UVA rays are longer so reach the inner state of the skin and causes skin damage.
What type of electromagnetic radiation can give you sunburn?
The main form of electromagnetic radiation that give you a sunburn is Ultra Violet (UV) radiation. (UV rays) Ultra-violet is furthered graded to UVa UVb and UVc. UVa - is necessary for the production of Vitamin D UVb - is required for certain anti-cancer process in the skin. UVc - has no beneficial function and is the most energetic and responsible for the majority of the sun burn.
Does Cold Weather Affect What if your Skin Color?
no, it does'nt affect your skin color. sunlight does make yor skin dark, staying inside the house won't.
