The sun's rays are divided into two types of ultraviolet radiation: UVA and UVB. UVB radiation burns the top layer of skin (the epidermis), causing sunburns.
UVA radiation is what makes people tan. UVA rays penetrate the lower layers of the skin where they stimulate cells called melanocytes to produce melanin.
Melanin is the brown pigment that causes tanning and is the means by which the body protects the skin from burns. People with dark skin tan more intensely than people with lighter skin because their melanocytes produce more melanin.
Keep away from sun exposure is only logical answer but who wants to live like a hermit? The key is
UVA rays make you tan, but can also cause serious damage. This is because the UVA rays penetrate the skin deeper than UVB rays. UVA rays can penetrate the protective layer, epidermis, and reach the dermis, where the blood vessels and nerves.
As a result, UVA rays can harm a person's immune system, making it difficult to fight the diseases and causing diseases such as melanoma, skin cancer more severe (and fatal).
Melanoma can be fatal. If not diagnosed and treated, the skin can spread to other organs of the body.
In the past, melanoma mostly affected people about fifty years or older, but dermatologists now have patients from twenty years old and even older teens with this type of cancer.
Experts believe that this is due in part to an increased use of tanning beds or sun lamps, which have a high UV content.
Doctors also believe that UVB rays play a role in the development of melanoma. This is because a sunburn or intense sun exposure can increase the chances that a person will develop this deadly cancer.
Exposure to UVB rays also increases your chance of getting two other types of skin cancer: basal cell carcinoma and skin cancer squamous cell carcinoma.
ven when you decide to protect your skin, you may sometimes want to look tan. Fortunately, many products on the market, without referring to sunlamps or tanning beds, will enable safe tan without sun.
A safe way to tan is with sunless self-tanning lotions. These "tans in a bottle" containing hydroxyacetone (DHA), which gradually stains the dead cells of the outer layers of your skin. "Tan" lasts until the dead skin cells desaparecen, así que exfoliarse o frotarse el cuerpo al bañarse con vigor hará que el color desaparezca más rápido. Típicamente, estos "falsos bronceados" duran de varios días a una semana.
Puede que quieras probar varias marcas de auto bronceadores para encontrar la que combine mejor con el tono de tu piel. Las opciones incluyen atomizadores, lociones y toallitas, y son fáciles de usar. Para obtener un bronceado delicado a toda prueba, utiliza uno de los hidratantes nuevos que contienen una modesta cantidad de un bronceador artificial, los cuales te permiten gradualmente llegar a tener algo de color sin dejar marcas o manchas, o el olor que algunas personas rechazan. Todas estas opciones también son económicas.
Ask a friend to help you apply self-tanning lotion on areas where you can not reach, like your back, for a uniform result. And make sure you wash the body areas that normally do not tan (like the palm of your hands and feet) otherwise, just seem to be dirty.
You may also want to check with salons that offer airbrush tanning is the system or "airbrush" in English. This type of tanning may look more natural with more consistent results. With the bronze of this type, the coach (a) of a beauty salon DHA solution connects to a compressor and spray spray tan on your skin.
The eyes, lips and nose are covered to protect them during this process, which takes five seconds to one minute. A few hours after application, you will begin to realize your new, safe tan.
With both methods, self-tanners and airbrush method, you get better results if you exfoliate your body skin with a special brush to exfoliate or a loofah sponge before applying tan. These combined approaches will match your skin tone and remove dead cells.
With both types of sunless tanning, you should still use sunscreen when you go outside to protect from sunlight. No fake tans generate melanin production, so do not protect you from sunburn. But all this good news is that you have the warm glow of a tan while keeping your skin beautiful for years to come.
