UVB
When it comes to ultraviolet rays, UVB is one of the most well known. This type of ultraviolet ray is actually responsible for more than 90% of all skin cancer cases.
While standing out in the sunlight may seem harmless, each time you do so, you are exposing yourself to ultraviolet B rays. This type of sunlight may only be able to reach and penetrate the skin's outer layer, known as the epidermis, but it doesn't take much for it to wreak havoc on your skin and in some cases, your health. Ever suffer from sunburned skin? You have 'B' rays to thank for that. These rays, also known as ultraviolet B, are the main cause of sunburn and tend to be at its strongest during midday.
Even though protection against UV rays should be done year-round, 'B' rays in particular are the most potent in causing skin damage during the summertime. Anytime you plan on going outdoors and being under the sun for a certain period of time, it is a must to wear sunscreen or sun block as well as protective clothing in order to prevent UVB rays from coming into contact with your skin. When choosing a sun care product like sunscreen or sun block, be sure to read the label and make sure the product you choose effectively blocks both ultraviolet B and UVA rays. Some formulas only provide protection against one or the other so your best bet is to be safe from both types of ultraviolet light.
The presence of ultraviolet B rays on the skin also results in the production of melanin, which makes the skin darker in color. Many people crave a tanned appearance and take their chances by exposing themselves to direct sunlight without any form of sun protection. This practice should be avoided at all costs. Instead of taking the risk of over exposure to UVB rays, it is better to achieve a tanned look through a sunless tanning lotion that doesn't need actual sunlight to stimulate the skin's production of melanin. This means you'll be able to get a tan without any worries about the effects of B rays on your skin.
