Sunscreen or Sunblock?

Midweek and I'm so blue..as in literally blue! from my earrings to my tank top, to my sparkling shiny bandana I'm blue. Ironically, in the inside I'm less blue. When T came last night I had a strange feeling that all's gonna be well.

Sunscreen or Sunblock? Been quite curious about the difference, if any, so I googled it to ease my wondering mind. Sunscreen acts literally like a screen. It filters UV (ultraviolet) from entering in our skin and the intensity would be based on SPF (sun protection factor). The higher the SPC, the lesser the UV can penetrate the skin. Sunblock on the other hand is what it is, it blocks UV from entering into our skin. Hard to determine the difference and I honestly know which one to use.

From About.COm..sunblock

Definition: Sunblock is different than sunscreen. A sunblock physically blocks the sun's UV radiation of the skin, both UVA and UVB. Examples of sunblocks are clothing, umbrellas, and trees. Chemical sunblocks scatter, reflect, and physically block UV radiation. The most well-known chemical sunblock is zinc oxide. Other commonly used sunblocks are talc, titanium dioxide, and red vetenary petrolatum.

From Wikipedia..sunscreen

Sunscreen, also commonly known as sun cream,[1] is a lotion, spray, gel or other topical product that absorbs or reflects some of the sun's ultraviolet (UV) radiation on the skin exposed to sunlight and thus helps protect against sunburn. Skin lightening products have sunscreen to protect lightened skin because light skin is more susceptible to sun damage than darker skin.
