Ultraviolet light can kill skin cells but infrared light only warms skin cells even though both types of lights are from the sun. Why is this, explain using the photon theory...?
NYSportsguy said:Moles are mutations in skin cells...not genes though. Gamma rays can mutate DNA strands.
UV light can cause damage to skin cells by penetrating the outer layers of the skin and damaging the DNA. This damage can lead to mutations and potential skin cancer. UV light can also break down collagen and elastin, resulting in premature aging of the skin.
In small doses, UV light can actually stimulate the production of vitamin D in the skin, which is essential for maintaining healthy bones and teeth. UV light can also help treat certain skin conditions, such as psoriasis and eczema.
UV light has a shorter wavelength and higher energy compared to IR light. UV light is responsible for causing sunburns and skin damage, while IR light is mostly responsible for heat and can penetrate deeper into the skin.
To protect your skin from UV and IR light, it is important to wear sunscreen with a high SPF, protective clothing, and seek shade when possible. Additionally, using skincare products with antioxidants can help neutralize the damaging effects of UV and IR light.
The safest way to tan is to use self-tanning products or spray tans, which do not involve exposure to UV or IR light. If you prefer to tan in the sun or a tanning bed, it is important to limit your time and always use sunscreen to protect your skin from damage.
