Is Your Sunscreen Preventing Cancer or Promoting Cancer?
We know by now that the old days of the 70s and 80s of roasting for hours in the sun are over!
So, we are aware of the importance of sun protection and we are also beginning to understand the potential risks associated with traditional sunscreen ingredients. While these products are designed to protect our skin from harmful UV rays, they often contain chemicals that can pose significant health and environmental risks.
What are the alternatives?
Let's cover some non toxic, chemical-free sunscreens, which offer a safer alternative. Let's explore the benefits of chemical-free sunscreens and the dangers associated with the chemicals found in many conventional sunscreens.
The Rise of MINERAL BASED or Chemical-Free Sunscreens
Chemical-free sunscreens, also known as mineral sunscreens, primarily use zinc oxide and titanium dioxide to create a physical barrier on the skin that reflects and scatters UV rays. These ingredients are not absorbed into the skin but sit on its surface, offering immediate protection upon application.
Here are a few of the key benefits of using chemical-free sunscreens:
-
Safer for All Skin Typs and Especially Sensitive Skin: Mineral sunscreens are less likely to cause skin irritation or allergic reactions, making them a better option for people with sensitive skin, children, and those with skin conditions such as eczema. However, do your own testing, like anything.
-
Broad-Spectrum Protection: Zinc oxide and titanium dioxide provide broad-spectrum protection against both UVA and UVB rays, ensuring comprehensive sun safety. This is my favorite go to when I am going to be in the sun for extended perriods.
-
Eco-Friendly: Unlike some chemical sunscreens, mineral sunscreens are generally considered a safer option for our lakes, rivers, oceans as well as marine life and coral reefs, reducing environmental impact.
The Dangers of Traditional Sunscreen Chemicals
Traditional sunscreens often contain a variety of chemical ingredients designed to absorb UV radiation. However, research has raised concerns about the potential risks associated with these chemicals. Here are some of the most common harmful chemicals found in conventional sunscreens:
-
Oxybenzone: This chemical is one of the most widely used UV filters in sunscreens. Studies have shown that oxybenzone can be absorbed into the bloodstream, where it may act as an endocrine disruptor, interfering with hormone function. It has also been linked to allergic reactions and skin irritations. Additionally, oxybenzone has been found to contribute to coral bleaching, posing a threat to marine ecosystems.
-
Octinoxate: Another common ingredient in sunscreens, octinoxate can penetrate the skin and enter the bloodstream. It has been shown to have estrogenic effects, potentially disrupting hormone balance. Octinoxate is also harmful to coral reefs, contributing to coral bleaching and damage to marine life.
-
Homosalate: This chemical helps sunscreen penetrate the skin more effectively but can accumulate in the body over time. Homosalate has been found to disrupt hormone activity and may have toxic effects on the liver.
-
Avobenzone: While avobenzone is effective at absorbing UVA rays, it can break down in sunlight, potentially leading to the formation of free radicals that can damage skin cells and accelerate aging.
-
Parabens: Often used as preservatives in sunscreens, parabens have been linked to hormone disruption and an increased risk of breast cancer. They can also cause skin irritation and allergic reactions.
Making the Switch to Chemical-Free Sunscreens
Given the potential risks associated with traditional sunscreen ingredients, many people are opting for chemical-free alternatives. When choosing a mineral sunscreen, look for products labeled "broad-spectrum" to ensure protection against both UVA and UVB rays. Additionally, select sunscreens with non-nano zinc oxide or titanium dioxide to minimize the risk of inhalation and ensure safer environmental impact.
Coconut Oil
Although not effective for long, extended time in the sun, Coconut oil has shown to offer about a 30 minute protection option for many. If you are particularly fair skinned, be careful.
Also, avoiding eating a lot of seed oils (Canola, sunflower,soybean, vegetable, peanut oils, to name a few) as this can make a sunburn worse.
As we become more conscious of the potential health and environmental hazards of traditional sunscreens, the demand for chemical-free options continues to rise. By choosing mineral sunscreens, we can protect our skin from harmful UV rays while minimizing exposure to potentially dangerous chemicals.
Always read labels carefully, stay informed about the ingredients in your skincare products.
Switching to chemical-free sunscreen is a simple yet significant step towards safer sun protection and a healthier future.
