Enjoy Your Summer And Stay Safe With Zinc Oxide Powder-Containing Sunscreen
Zinc oxide is a kind of mineral that comes in white powder form and cannot be dissolved in water. It is commonly used as a mixture to a lot of commercial and industrial materials such as sunblocks, sunscreens, pharmaceutical products, plastic products, cement, paints, adhesives, glass, ceramics, ointments, sealants, batteries and tapes used for first aid.
Zinc oxide is effective when applied to protect the skin from eczema, from mild rashes and redness, and as astringent to cleanse the skin of impurities. It becomes more effective when used together with other skin preparations.
Photostability is the damage-free characteristic of a molecule when exposed to extreme radiation in the environment.
Sunscreens that are photostable are what we should look for when choosing the kind of sun protection for our trip to the beach this summer.
You should buy a sunscreen or sunblock that contains zinc oxide, a sunscreen ingredient that has been proven to be effective against a wide range of microorganisms, stable when applied to the skin, and certified as safe.
Morover, zinc oxide powder is very easy to incorporate with other types of sunscreens because it is mild enough for everyday skin care and versatile to use with other chemical components such as water-proof sunblocks.
A 2000 publication of the Journal of Dermatologic Surgery stated that compared to titanium dioxide, zinc oxide provides better protection against ultraviolet A and gives a better skin whiteness appearance on the skin.
If you are exposed to the sun most of the time, regular use of a sunscreen that contains zinc oxide is strongly suggested to protect you from harmful ultraviolet rays, skin disorders caused by radiation and various types of skin cancers. It can significantly reduce your risk of having squamous cell carcinoma and precancerous solar keratosis.
Developing melanoma is not directly associated with the mere application of sunscreens on the skin but can be attributed to the way people behave and act when using these skin protection formulas.
A large portion of the ultraviolet radiation that reach the surface of the earth is ultraviolet A which is said to be responsible for a wide variety of skin problems brought about by long periods of exposure to the sun.
Ultraviolet light is invisible but its effects on the skin can be felt when a person gets a sunburn after long periods of exposure to the sun. The protection that a sunscreen exerts on the skin is determined by the sun protection factor or SPF. The SPF measures the amount of time it takes to burn skin that has been applied with sunscreen.
A professor of Preventive Medicine and Epidemiology at the University of California in San Francisco said that 90 percent of age-related changes in the skin are caused by sunlight. Radiation caused by ultraviolet rays of the sun is stronger today than 50 years ago due to the thinning of the ozone layer that prevents the harmful rays of the sun from reaching the earth's surface.
Dark-skinned people has a slower rate of aging than their light-skinned counterparts because their skin has more melanin content. Melanin, the pigment that gives the skin a dark color, absorbs sunlight and protects the skin from damage caused by ultraviolet radiation.
Sun Protection Factor is further described as the relationship of the smallest amount of energy coming from the sun which is needed to cause a mild erythema on a sunscreen-protected skin to the same measure of energy needed to produce erythema on a skin that is not protected by sunscreen.
Some sectors have raised concern about the harmful effects of zinc oxide particles in the skin claiming that these tiny particles might be absorbed by the skin consequently causing serious harm to the person using it.
Well, you have nothing to worry about, you can continue using your favorite sunscreen. According to the November 2011 issue of the Biomedical Express Journal, it reported that a joint study conducted by scientists from Switzerland and Australia found that the very tiny zinc oxide particles are not absorbed by the innermost layer of the skin thus making the application of sunscreens with this ingredient safe as ever.
In an article published in the Journal of American Photobiology, it stated that SPF does not comprehensively determine how sunscreens protect from the UVAI with 340 to 400 wavelength.
It further stated that up to this day, there has been no single method used to measure the efficacy of UVA products.
Research studies further show that sunscreens are effective in protecting against the harmful effects of ultraviolet rays.
Copacabana is one of the most famous beaches in the world located in Rio de Janeiro, Brazil. It is the theme of one of Barry Manilow's famous songs with the same name, Copacabana.
