Use your common sense when exposing yourself to the sun and listen to your doctor’s advice when it comes to suncare and safe sun tanning time.To use the UV-calculator, you need to know your skin type. Basically a low number means a higher risk of skin damage. Consult the above table if you don’t know what skin type you have.
If you’re not sure, rather underestimate your skin type. For example, you’re not sure whether you really are a type 3, then choose type 2. And ask your doctor the next time you visit him.
if you want to avoid getting skin cancer, sun protection is a necessitiy*,`
I tried it for today’s date using accurate information. Even though the uv-index was set to 11+, my results were 15 hours and 9 minutes on a sunny day. I dont care how high my spf is or how much suncreen I put on, if I saty in the sun that long I am going to get burned
Your results were that high because you didn’t specify your SPF. It is essential for the calculation.
for skin care, you can use those topical vitamins, copper peptide and stuffs like that*.*

This is great! Many people forget even if its cloudy you can still get a wicked sun burn cause the UV factor is high.
Thanks for introducing me to the calculator. Hope it will be useful me.
this is excellent! i’ve been looking for a tool like this that takes skin type into consideration. Great work!
cool tool
Do you know how to calculate SPF theoretically?
For example, if there is 2% Titanium dioxide in the sunblock lotion, 2% of Titanium dioxide will give at least 2 SPF units
I wish I could download this to my Mac, or my iPhone so I have it when I’m not able to get on the net. (Great to have when I’m out on the water.)
Great website!! Keep up the good work!!
