What is the best sunscreen to prevent sunburn?
Overall, the safest and most effective sun-protection products are pure zinc and/or titanium-based sunblocks. These two ingredients have been around a long time and boast great safety data. The ideal sunscreen blocks both ultraviolet A and B (UVA and UVB) rays, is stable, doesn’t break down in the sun, and doesn’t get absorbed through the skin. Is there any difference between sunscreens and sunblocks? Physical sunscreens like zinc oxide and titanium dioxide are sunblocks; they physically (like a brick wall) block both UVA and UVB rays. Besides these two, all other sunscreens are chemical-based sunscreens.
