We all use sunscreen to protect from the sun and the effects of these rays but it appears that using just any sunscreen you find has it’s own effects
So we provide a few guidlines and critical knowledge on how to find the best chemical free sunscreens.
Chemical Ingredients to avoid in Sunscreens
It is necessary to know that there are chemical substances with the capacity to produce alterations in the hormonal system of those of the human bodies, this type of components are known as endocrine disrupts, they are highly harmful for the organism, especially in children and pregnant women, and the use of solar protectors with this compound should be avoided.
These substances are also known as hormonal pollutants, and can cause a decrease in sperm count, type 2 diabetes, damage to childhood brain development, and prostate and breast cancers.
Ethylhexyl methoxycinnamate and benzophenone 3 are some of these endocrine disrupts, and sunscreens with the presence of sun filters such as cyclopentasiloxane, cyclohexasiloxane, BHT, Butylphenyl methyl propional, salicylic acid and parabens should be avoided, as they are suspected of having endocrine disrupting characteristics and causing ecological damage, are not biodegradable and cause damage to marine ecosystems.
Why nano titanium dioxide should be avoided
This substance is a mineral salt, which when exposed to UV light produced by the sun’s rays is converted into an oxidation catalyst, producing hydroxyl radicals and superoxide ions that are twice as strong as chlorine and stronger than an ozone disinfectant.
The particles of this substance accumulate in the organism, and this one does not have capacity to eliminate them when the skin this burned or mistreated, in addition exists suspicions that the particles of this component can cause inflammation in the lungs.
The main function of these screens is to prevent any type of radiation from reaching the skin.
Because information about the ingredients that make up these products is scarce, it is difficult to find the right ones. When it comes to looking for non-toxic ones, one must look for those that cause damage to the epidermis, while at the same time keeping it hydrated.
- You should look for screens with high SPF, this is the sun protection factor, generally those of 30 are the most efficient for sun protection, since the higher SPF contains more chemicals.
- You should look for sunscreens that do not contain chemical filters, look for physical filters, without nanoparticles, because they can be absorbed and enter the bloodstream and cause damage to the body.
- Even if you sacrifice comfort, don’t look for spray-on protectors, as they release particles that are toxic if there is a risk of inhalation.
- Prefer biodegradable sunscreens, this way you avoid contamination of marine environments.
Myths about organic sunscreen
- The whole family can wear the same protector, well it can but really it not advised. This depends basically on both ages and skin types, for example a child should wear a protector with a higher degree of protection than an adult.
- The application of several layers produces more protection, this is very doubtful, the fact of applying more quantity does not increase the protection.
- The durability is several years, this depends on the conservation conditions and the expiration dates of the products.
- One daily application is enough, this myth is extremely false, it is required to apply the protector at least every two hours, to preserve its effectiveness.
- On cloudy days the protector is not necessary, this is a lie, the ultraviolet radiations that are the cause of the burns cross the clouds.
Prohibition of products with oxybenzone and octinoxate in Hawaii
Representatives have passed a law in Hawaii to ban the use of oxybenzone and octinoxate as an environmental conservation measure, aimed at reducing pollution directly on coral reefs.
According to scientific studies it was demonstrated the toxicity of these two substances, harming the existence of corals, sea urchins, fish, marine mammals, turtles and algae.
This example from Hawaii has had repercussions in other areas such as Palau, Bonaire, the Virgin Islands, Aruba, the Marshall Islands, and Key West.
