With the warm weather among us, more of our skin is being exposed, and for longer periods of time. Overexposure to the sun’s UV rays can severely damage our skin and the underlying tissues. To protect ourselves against the sun’s harmful UV rays, the American Cancer Society recommends the use of sunscreen. UVA rays can cause DMA damage to skin cells deep underneath the surface and increase the risk of malignant melanomas, while UVB rays burn the skin surface.
There are two different categories of sunscreen based on their action: chemical sunscreens absorb UV rays while physical sunscreens reflect them. Physical sunscreens (containing titanium dioxide and zinc oxide) block a wider range of UVA/UVB rays, offering the skin more sun protection without the potentially irritating chemicals. Titanium dioxide and zinc oxide do not break down as quickly as the ingredients in chemical sunscreens, reducing the need for reapplication throughout the day.
Some concern lies with sunscreens that contain nanoparticles (between 1 and 100 nanometers) of zinc oxide and titanium dioxide, as these particles small enough to absorb into the skin and enter skin cells and cause damage. However, as non-nanoparticles, zinc oxide and titanium dioxide are safe and sit on the skin’s surface to reflect UVA and UVB.
SPF (Sun Protection Factor) measures the power of the sunscreen’s effectiveness against UVB rays, and is calculated by comparing the time needed for someone to burn with and without a particular sunscreen. For example, if it takes 10 minutes to burn unprotected, wearing a SPF 30 should protect the skin up to 30 times longer (300 minutes). Higher SPF means longer protection, however it is still extremely important to look for a broad-spectrum sunscreen that protects against UVA as well as UVB.
100% Pure SPF products are safe, effective, and non-comedogenic. We use physical sunblocks (and never in nanoparticle form) in the healthiest, most skin nourishing ingredients to create effective yet ultra lightweight SPF moisturizers like the Argan Oil Hydration Facial Moisturizer SPF 30 and Organic Pomegranate Antioxidant Hydration SPF 20.
