Terms You Need To Know When Buying Your Next Tube Of Sunscreen For Your Family
Protecting oneself from the dangerous rays of the sun is one of the most important things to do in life. Sunscreen aids in this protection by reflecting, absorbing, and/or scattering harmful rays that the sun casts on earth.
Sunscreen is available in several different forms: lotion, spray, gel, cream, and even makeup. Not using sunscreen can give unwanted aging of the skin, and even worse – skin cancer.
When buying sunscreen, it is important to be able to read the label on the container to find out what is contained in the bottle. There are some words that might not be understood; some of them are:
* UVA (Ultraviolet A) – This sneaky ultraviolet radiation has a lengthy wavelength that penetrates the skin to reach further depths. These rays are very harmful because they can be working against the skin without it being felt.
* UVB (Ultraviolet B) – UVB is a kind of light that the sun emits. The wavelength of this type of radiation is simpler than UVA and usually leads to sunburn and other skin problems.
* SPF (Sun Protection Factor) – This denotes the strength of protection that a particular sunscreen gives for sun exposure. A number is labeled on each container of sunscreen indicating the strength of it. The higher number provides more protection than the lower numbers. It is mentioned that someone being exposed to the sun use at minimum, SPF 15 to the body periodically and reapply If the sunscreen comes off.
* UVR (Ultraviolet Radiation) – This stuff is real radiation from the sun that can cause premature aging, spotting, sunburn, wrinkles, and skin cancer in some. Furthermore, UVR rays can reduce the effectiveness of one’s immune system.
* Water Resistant – Some sunscreens are actually water resistant in that they stay on the skin longer and are said to withstand water from the pool, ocean, or any other type of water source. Swimmers can go for longer without having to reapply and still be protected. However, it is a good idea to reapply sunscreen, even if it is water resistant, because it looses its effectiveness through more and more swimming. Water resistant does not mean water proof.
In addition to the different terms on sunscreen bottles, there are also two kinds of sunscreens: physical blockers and chemical blocks. Physical blockers like in the name, physically block bad sunlight by reflecting back the harmful UVA and UVB radiation. Chemical blockers though absorb some of these harmful rays; typically the ones with shorter wavelengths.
Whatever type you purchase, it is important to be liberal in applying it and be mindful if it is rubbed off. Sunscreens can only be as effective as the person applying them – people being exposed to a lot of sun must lotion thoroughly and reapply every two or so hours. The sun can be a great and beautiful thing to be with outdoors. Though, it can be your worst nightmare if you fail protect your skin. Informing yourself on what to look for in a sunscreen will lower the risk of skin cancer and other horrible conditions of the skin.
