We tan under the sun because our skin produces more melanin, a pigment that darkens the skin, as a natural defense mechanism against harmful UV rays.
A tan from sun exposure typically lasts for about 1 to 2 weeks before fading.
It typically takes about 2-3 days for a tan to develop after sun exposure.
No. Heat from the sun is not what causes tan it is the ultraviolet rays similar to the rays that cause skin cancer. The reason heat is asoociated with them is that usually when the sun is bright enough that the UV rays are causing a tan infrared rays are also causing you to feel hot. This is why a bright sun on a cool day is very dangerous. The UV rays are still reaching the skin but as they are undetectable and there is no heat warning the skin that the sun is bright you are more likely to allow yourself to stay in the sun too long and burn.No.
If you are a habitual smoker, chances are you will get wrinkles under your eyes. Being out in the sun too long can also cause eye wrinkles. You can also get under eye wrinkles if your eyes spasm.
When you sit in the sun, your skin produces more melanin, a pigment that helps protect the skin by absorbing ultraviolet (UV) radiation. The increase in melanin production causes your skin to darken or tan as a way of defending against the sun's damaging effects. Tanning is your body's natural response to help shield your skin from UV damage.

A sun lamp is a lamp used as a substitute for sun light. People lay under them to tan their skin. A sun lamp can also be a big lamp used for film making.
because the sun gives them a tan
The sun's rays are stronger at higher altitudes , which can make tanning and burning happen more quickly. People with darker skin will tan faster because they have more melanin in their skin. This may make them tan more because sun triggers cells called melanocytes to produce melanin, which makes the skin darker.
Sun tan oil is used to help achieve tanned skin. Many sun tan oils are infused with bontanicals. Other ingredients in sun tan oil include Mineral Oil, Cocos Nucifera and Aloe Barbadensis Leaf Extract.
