Switch chemical sunscreen for natural sunscreen
You shouldn’t have to choose between skin cancer and breast cancer. We all know that sunscreen is must when protecting your skin from damage caused by the Sun’s harmful rays. Unfortunately, some ingredients in chemical sunscreens cause irritation, allergies and hormone disruption. Read More Some ingredients, ironically, are unable to withstand powerful UV radiation without losing their effectiveness and others form potentially harmful breakdown products when exposed to sunlight. Chemical-based sunscreens absorb UV radiation before it can penetrate deeply into the skin and cause damage. Chemical sunscreens often contain ingredients known as ‘penetration enhancers’ which help the product adhere to the skin, however, this results in the chemicals themselves being absorbed into the body where they have been measured in blood, breast milk and urine samples, according to the Environmental Working Group’s cosmetic safety database. Natural sunscreens, on the other hand, contain mineral filters like zinc oxide and titanium dioxide. These ingredients are designed to sit on the skin’s surface and act like a physical barrier which deflects the Sun’s harsh rays.
In conventional sunscreen formulas, zinc oxide and titanium dioxide leave a white layer on the skin, but when these ingredients are reduced to nanoparticles, they become invisible while still providing broad-spectrum protection. This has led to an increase in the use of nanoparticles in sunscreen in recent years. However, the use of nanoparticles in sunscreen has led to concern as to whether these nanoparticles might be absorbed into viable cells below the skin’s surface, risking damage to these cells. According to the Therapeutic Goods Administration (TGA), the potential for nanoparticles in sunscreens to cause adverse effects depends primarily upon the ability of the nanoparticles to reach viable skin cells. The TGA also states that, to date, the current weight of evidence indicates the particles remain on the surface of the skin and in the outer dead layer of the skin. In Australia, sunscreen manufacturers are required to list their active ingredients on their products but there is no requirement to state particle size. Until this particular debate is resolved, Naturally Safe Cosmetics has made a conscious decision to stock only nanoparticle-free sunscreen Read Less
