What are the different categories of Sun Protection products?
There are 2 main types of sun protection products: Chemical Sunblocks and Physical Sunblocks. Chemical sunblock works by absorbing the high energy from UV rays and release it at much lower energy level. This category of sunblock needs to be applied about 30 minutes before sun exposure to be effective. Examples of this category of sunblocks are PTR Ultra-lite Oil-Free sunblock and Beach and Pool Sunblock. On the other hand, physical sunblock contains Titanium Dioxide or Zinc Oxide that physically blocks the UV ray, and therefore can be effective immediately upon application. The all new Instant Mineral SPF30 is an excellent example, combining instant protection and convenience in an innovative package. Of course, some bright sparks have thought about combining these 2 categories, and the result is PTR’s Oil-Free Sunblock SPF30, which contains both Oxybenzone and Titanium Dioxide, providing full spectrum protection against the sun.
