protect your skin from the sun

Summer is coming and prepare to go to take the sun and get tanned. This must be done with caution because our skin is jeopardized not only burn but skin cancer.

For your skin remains perfect, it is essential that whenever you do it out of the sun with sunscreen with minimum SPF 15. Whether you use a factor of lower denomination does not mean you will put more brown but the exposure time is going to protect will be lower. Words, if your unprotected skin takes 5 minutes to burn and you get a protection factor 10, multiply these by 10 by 5 minutes you could be 50 minutes, depending on you to be darker. That initial five-minute time increases, because the dark is the way to protect your skin from the sun. For this reason, lie always high protection factors to be protected longer.

The cream should aplicártelo 1 / 2 hour before exposure to dry skin and extending it.
Enjoy the summer, protect your skin from the sun

You must reapply every 2 hours.

If you bathe and protection that you put on is water resistant to lend again to dry off.

Avoid sun exposure between 12 and 16 hours as is the portion of time in which the sun is much more harmful to our skin as it affects most directly.

Exposures Start slowly and do not put for hours the first day, start with 10 minutes and gradually increasing the time is not longer than two continuous hours of sun exposure.

After a day at the beach just take a cold shower and you put a moisturizer or after sun.

Cryotherapy applied nitrogen or argon gas at extremely cold temperatures to destroy diseased tissue. To destroy diseased tissue located outside the body, liquid nitrogen is applied directly with a cotton swab or spray. For tumors located below the skin surface and depth in the body, the doctor uses imaging guidance to insert one or more applications, or cryoprobes through the skin to the site of diseased tissue and then deliver the liquid nitrogen or argon gas.

Living tissue, healthy or sick, can not tolerate extremely low temperatures, and die due to:

* Ice in the fluid outside the cells, resulting in cellular dehydration.
* Ice within the cell. At approximately -40 ° C (-40 ° F) or less, begin to form intracellular ice crystals can break lethal than almost any cell.
* Blast the cell swelling or shrinkage. If ice forms only outside the cell, osmosis (the movement of a solution through the membrane of a cell) causes the cell to shrink and let out water inside to replace the water that has become on ice. Then, when the area thaws, the water re-enters the cell rapidly shrinking and makes it explode. Thus, cryotherapy usually consists of a series of steps in which tumors are frozen and thawed several times.
* Loss of blood supply. Cells die when the ice that forms in the small blood vessels destroys the tumor’s blood supply, causing clotting. Since the average time to clot blood is approximately 10 minutes, keeping the cold for at least 10 to 15 minutes to make unless the temperature of tumors suggest that lethal-ice temperatures have already been reached.
