Ultraviolet radiation from the sun is generally grouped into bands A and B. Both contribute to the development of skin cancer and protection from both is needed. UVB is filtered by a number of protective chemical lotions, many of which are easy to apply and essentially invisible. It is important to note however that UVB filters alone do not provide complete protection.

Maximum sunscreen protection is offered by combination/broad spectrum products which combine the UVB chemical filters with micronized titanium dioxide. The titanium cannot be rubbed into the skin so it remains on the surface. These preparations are invariably thicker, a little more difficult to apply, and leave a slightly opaque (usually faint white) layer on the skin surface. These combination/broad spectrum sun screens offer the best protection and are highly recommended.

Applying sunscreen lotions

Use a sunscreen with sun protection factor (SPF) of 30+, and which is also broad spectrum and water resistant, no matter what type of skin you have. Apply sunscreen 20 minutes before going out and reapply every 2 hours, after swimming or any activity that causes you to sweat.
