Sunscreen or Sunblock?


Many people do not realize that there is a difference between sunscreen and sun block. It is important to chose the right protection for you skin.There are two types of protective lotions; chemical and physical.

Sunblock (physical) contains organic and non-organic ingredients that remain on top of the skin to form a barrier between your skin and damaging UV rays by reflecting UVB light. Look for sunblock products with octyl methoxycinnamate, octyl salicylate, and octocrylene.

Sunscreen (chemical) penetrates the skin and absorbs the UVA rays before they are able to damage your dermal layer. Look for sunscreen products with zinc oxide, titanium dioxide, and ecamsule.

Sunblocks are formulated to shield against UVB rays, while sunscreens protect against UVA. In order to fully protect your skin, choose a broad-spectrum protection formulated sunscreen that will protect against both UVA and UVB rays. Formulas often contain a mixture of both sunblock and sunscreen.

Ideally, you should use a lotion with SPF of 30 or higher, apply 30 minutes before sun exposure, and reapply after each hour of sun exposure.
