Why I only wish to use mineral sun filters
Most of us love the sun, including me – and there’s a lot of benefits of letting the warming sunrays kiss our skin. D-vitamin is one of the most well-known benefits, but research also highlights benefits related to lowered blood pressure and increased happiness, when being exposed to sunlight.
In a time where concerns about sunscreen’s negative effects on our bodies are being discussed extensively, especially in the foreign press, I have considered whether it was best to completely avoid sunscreen and just use my common sense when being in the sun. I found the options on the market insufficient and I couldn’t find a sunscreen that I felt good about using on my family or myself.
There are three types of UV filters that skincare manufacturers can use in the formulation of sun protection.
/ Physical, mineral filters – which is used by Karmameju
/ Nanoparticle UV filters – UV filters in nano size
/ Chemical UV filters
I only want to use sunscreen with mineral UV filters, as they stay on the surface of the skin. Mineral UV filters do not penetrate the skin causing a chemical reaction to protect against UV rays. But to me, the issue with physical, mineral UV filters is that they leave a white residue and sticky feeling on the skin, or they contain high levels of silicone to make the sunscreen easier to apply. Consequently, I was left without a useful solution – which made my wish to develop a Karmameju suncare range even bigger. A sun range for everyone in the family.
Here’s a brief explanation of the three types of UV filters.
Physical, mineral UV filters
Titanium Dioxide and Zinc are mineral sun filters that consist of naturally derived minerals, extracted from the soil. Physical UV filters are applied like a film that protects the skin, by reflecting the UV rays. Sunscreen with physical filters is known to be difficult to apply and leave the skin with a white residue, which is not the case with Karmameju SUN. Our innovative formulations are both sheer in appearance and a sheer pleasure to apply. We use the mineral UV filter Titanium Dioxide.
Nanoparticle UV filters
Many ingredients can be made in microscopic nano size. The nano mineral filters have been created to make them less visible and sticky. Very little is known about the potential risk factors for nanoparticles in general. Therefore, nano ingredients should always be listed with nano in parenthesis by the name: Titanium Dioxide (nano), so that the consumer can see that nano ingredients are being used in the product.
Chemical UV filters
Chemical filters are synthetic. They contain substances that penetrate the skin. When UV rays reach the skin, chemical filters absorb the UV radiation and transform it into heat. Many skincare brands use chemical filters as they are not visible on the skin when applied. No chemical filters are approved by ECOCERT / COSMOS, an official organisation that certifies natural and organic products. Several chemical filters are also known to be harmful to the ocean and the endangered coral reefs.
