Learn about Zinc
What is Zinc?
Zinc is a natural mineral that provides broad spectrum protection against ultraviolet rays (as zinc oxide). We use an uncoated certified natural pharmaceutical grade zinc oxide in all of our products.
Zinc oxide has always been well regarded as the best broad spectrum UV protector available, but originally had limited use due to its thick and white or fluro-coloured appearance.
Today, through patented processes and new technology, we are able to create sunscreens made from certified natural zinc oxide that provide very high broad spectrum protection against UV rays and dry clear on your skin.
How does a Zinc sunscreen compare to chemical-based sunscreens?
Zinc Oxide is the only UV protector, with global regulatory safety acceptance, that provides broad spectrum protection against both UVB and UVA.
Chemical-based sunscreens typically include a combination of two to six of the following active ingredients: oxybenzone, avobenzone, octisalate, octocrylene, homosalate and octinoxate.
There are several benefits to using Zinc over chemicals.
Zinc is safe on skin, and for the environment
Zinc oxide has a long history in skincare products such as calamine lotion and nappy rash creams, for use on even the most sensitive of skin.
There are studies that show chemical UV filters can generate free radical damage and endocrine disruptions or damaging your hormones and DNA at a molecular level. Zinc oxide has shown no evidence of these impacts or hormone disruption.
Recent findings by the U.S. Food and Drug Administration (FDA), have shown chemical ingredients used in most sunscreens absorb into the body and can be measured in blood after just a single use and can remain for weeks thereafter.
Some chemical UV filters have recently been banned by Government authorities in USA and Australia due to known damage being caused to coral and ocean life.
Zinc doesn't ignore UVA protection
UV light consists of UVA and UVB rays, with both contributing to skin damage caused by sun exposure.
Many chemical UV absorbers provide none or inadequate UVA protection.
UVA light damages the skin at a deeper level, causing the skin to lose its elasticity, which leads to wrinkles and sun spots. UVA light was previously believed to wreak mostly cosmetic damage, but new studies show it's linked with cancer too.
SPF ratings only measure protection from UVB, leaving out potential damage from UVA. As UVA wavelengths are not accounted for, skin may not be protected from the full range of cancer-causing UV radiation by simply using a sunscreen that has high SPF.
Our zinc has been specifically designed to enhance the UVA protection performance and offers market-leading protection across the UV spectrum.
Zinc works in the real world
Chemical UV filters may theoretically protect against UV rays in lab settings, however have been found to degrade and destabilize in as little as 30 minutes when exposed to actual sunlight limiting or preventing them from protecting you.
Avobenzone in particular is widely known to degrade rapidly upon exposure to UV light, which is a common chemical absorber that targets UVA protection. Avobenzone requires numerous other chemicals to maintain some degree of stability.
Ethical Zinc's physical zinc oxide barrier keeps working under real world conditions, maintaining very high broad spectrum UVA and UVB protection as a singular active ingredient.
