SUN is the energy source for everything living on the earth.
After cold gray days of winter,we deserve to enjoy the summer going to the beach ,BBQ and a little sun-kissed color on your skin to look healthier but we must understand how to be safe in the outdoors and educate your children how to protect themselves form THE SUN.
The ultraviolet rays in the sun can stimulate the skin to produce a large number of oxidative free radicals,which may damage the skin tissue,accelerate the oxidation of melanin,thus making skin become more rough,dull and lose elasticity.
I encourage all my clients to invest in good sunscreen every year.Must have UVA/UVB protection (titanium dioxide,zinc oxide).
If you use sunscreen generously and frequently,a bottle of sunscreen shouldn’t last from one year to another.But Sunscreens are designed to remain at original strength for up to 2-3 years so you can use left over sunscreen from last year. (Please check the expiration date and make sure the bottle was stored in dark, cool place).
American Academy of Dermatology recommends using a broad-spectrum sunscreen with an SPF of 30 or more. Apply sunscreen generously 20 to 30 minutes before going outdoors and reapply about every 2 hours- or more often if you are swimming or sweating.
Q:What is SPF?
A:Sun Protection Factor
Here is how it works:If you are using SPF15,and it usually takes 15 minutes to get sunburn,all you have to do is multiply the two numbers together to figure out how long your sunscreen should last 15×15=225minutes (3 hours and 45minutes)(source: WebMed)
Using oil on the skin ,such as mineral oil will increase the amount of sunlight absorbed by the skin without any benefit of protection.It’s very much like using a frying oil to transfer the heat from the stove to the meat one is cooking.
