Photoaging...cont'd

A slightly different way to go is with sun blockers. Whereas sunscreens keep out the harmful rays and allow beneficial light frequencies to pass into the body, sunblocks reflect rays of all wavelengths.

Which is the better approach? That will depend on whom you ask. It can be argued that while screens may have some chemical constituents, blockers deprive the body of needed light stimulation. At the end of the day, you may want to consider your individual lifestyle and skin type and make a decision accordingly. You could even use both; sunblock on your face, neck and décolleté, (since these areas are particularly susceptible to damage) and sunscreen on the rest of your body. Either way, the bottom line is to get the protection; and by its own means, each system will provide that if properly applied.
