BROAD SPECTRUM SUNSCREEN PROTECTION
When looking for sun protection, always look for a broad spectrum sunscreen. Broad Spectrum sunscreen means that the sunscreen will provide protection from both the UVA and UVB light spectrum.
WHAT IS SUNLIGHT MADE OF?
Sunlight causes premature aging of the skin and many different types of skin cancers. Exposure to ultra violet radiation accounts for more than 90% of today’s skin aging and skin cancer issues. Sunlight consists of both visible and invisible rays know as UVR (ultra violet radiation), which includes both UVA ultraviolet light and UVB ultraviolet light. UVA rays are longer and tend to penetrate more deeply into the skin. UVB rays are shorter rays that create most of the sun burning, sun tanning and sun damage. Broad spectrum sunscreen does not protect against the UVC radiation because this level of light is almost completely absorbed by the ozone layer and does not affect the skin.
There is no such thing as safe UVR, and therefore, no such thing as a safe tan.
BROAD SPECTRUM SUNSCREEN ACTIVE INGREDIENTS
WHAT TO LOOK FOR:
For UVB protection, look to these active ingredients for broad spectrum sunscreen protection:
- Octisalate
- Octinoxate
- Homosalate
- Oxybenzone
- Micronized Titanium dioxide (note, this crosses into UVA light spectrum)
For UVA Protection, look to these active ingredients for broad spectrum sunscreen protection:
- Oxybenzone
- Micronized Titanium dioxide (note, this crosses into UVB light spectrum)
- Micronized Zinc Oxide
- Oxybenzone (note, this crosses into UVA light spectrum)
- Avobenzone
Rocky Mountain Sunscreen provides broad spectrum sunscreen protection. Rocky Mountain Sunscreen incorporates all of the above UVB active ingredients as well as oxybenzone and micronized titanium dioxide for UVA protection. These broad spectrum sunscreen ingredients vary by each SPF.
HOW IS BROAD SPECTRUM SUNSCREEN MEASURED?
Sunlight is measured in “nanometers”, which is a unit of measure for UVA, UVB and UVC ultra violet radiation (UVR).
UVA Rays: 320-400 Nanometers (Broad Spectrum Sunscreen Protection term applies)
UVB Rays: 290-320 Nanometers (Broad Spectrum Sunscreen Protection term applies)
UVC Rays: 100-290 Nanometers (Broad Spectrum Sunscreen Protection term DOES NOT apply)
In summary, always make sure the phrases “broad spectrum sunscreen protection” or UVA / UVB broad spectrum sunscreen protection are used when purchasing sunscreen.
