Chemical sunscreens contain many harmful ingredients that can alter hormone levels and disrupt your endocrine system.
Myth
The higher the SPF, the better.
False
The optimal SPF should be 15 to 20. After this, increases in protection are minimal and when the SPF factor increases, the amount of chemicals increases as well.
Some of this chemicals have been shown to be converted into free radicals by the sun.
Myth
The longer I stay in the sun without protection, the more Vitamin D my body makes.
False
Our skin only creates Vitamin D for the first 20 min of sun exposure. After that UV rays destroy Vitamin D in the skin, so levels actually decrease the longer you stay in the sun without protection.
