Sunscreen vs. Sunblocks.
What is the difference between sunscreen and sunblock lotions?
The major difference between sunblocks and sunscreens is that sunblocks are mineral based (always) and sit on the surface of the skin. The active ingredients are zinc oxide and titanium dioxide. Sunscreens are generally chemical based and must be absorbed into the skin to be effective via a chemical reaction with the UV rays. Ingredients vary widely, as does their safety. So the next time you apply a "sunscreen or sunblock" on your baby think "SUNBLOCK " "NATURAL"
