Sunscreen and Sunblock
What's the Difference?

Sunscreen and Sunblock 1 Does anyone truly understand the difference between sunscreen products and treatments that are formulated as sunblocks?

Although it is obvious, sunscreen's function is to "screen" the sun while sunblock actually "blocks" the sun.

In anti-aging skin care it is critical to prevent the sun from damaging the skin any further.

Therefore, the best option for those interested in rejuvenating their aging skin is a sunblock.

Look up the difference between sunscreen and sunblock and you will find that the difference between the two is quite significant.

Sunscreen is defined as ". . .a screen to protect against sun or a preparation applied to the skin to prevent sunburn (as by chemically absorbing ultraviolet radiation)."

While sunblock is defined as ". . .a preparation applied to the skin to prevent sunburn (as by physically blocking out ultraviolet radiation)."

It is important that which ever sun care product you chose that it protects against both the sun's UV (ultraviolet) rays, on the UVB and UVA spectrum. In other OTC sun products look for one of the following ingredients:

Active ingredients found in sunscreens:
  • Aminobezoic Acid
  • Avobenzone
  • Benzophenone
  • Cinoxate
  • Dioxybenzone
  • Ensulizole
  • Homosalate
  • Meradimate
  • Octisalate
  • Octinoxate
  • Octocrylene
  • Oxybenzone
  • PABA
  • Sulisobenzone
  • Trolamine Salicylate
Active Ingredients found in sunblocks:
  • Iron Oxide
  • Titanium Dioxide
  • Zinc Oxide
As you can see with the extensive list of sunscreen ingredients and sunblock ingredients, it can be quite difficult selecting a product that is right for you and your skin type.
