Toxic filters in sunscreens.

Toxic filters in sunscreens.

It's no secret that the sun (in moderate doses) provides all kinds of health benefits, including the production of vital vitamin D. However, with warmer weather during the summer months, many people are looking for the best sunscreens to reduce the risk of sun overexposure, sunburn and possibly skin cancer.

But this is where the problem starts. Most of the sunscreens on the market simply do not offer adequate protection from the sun and even many of the ingredients used in them are actually harmful to our body. In fact it is important to remember that the skin is the largest organ in the body and one of the most complicated. It has many roles in maintaining our health, but it also has many potential problems, with more than 3,000 potential skin disorders, many caused by the use of toxic chemicals including sunscreen.

In addition to a study conducted by the FDA in January 2020, which found that “chemical ingredients in sunscreens are systematically absorbed after one application, and some ingredients can remain in the blood for at least 3 weeks ”.

The most common sunscreen chemicals in any sunscreen include avobenzone, oxybenzone, octocrylene, homosalate, octisalate, and octinoxate, and all six active ingredients tested were readily absorbed into the bloodstream of the humans in the study, and in concentrations that exceed an important FDA safety threshold.

Beyond health issues there is another important issue:

How many of the sunscreens actually offer real protection?

The official 2020 report published in May found that almost 75 percent of sunscreens do not work and/or contain truly toxic ingredients that are easily absorbed by the body.

Are you using the best sunscreen or the cheapest?

At the moment, lower quality products continue to be the best sellers on the market, despite scientific evidence that assures us of the use of harmful ingredients and that they are formulated with products that may not adequately protect users from dangerous UVA rays.

The same earlier EWG report cited research by Brian Diffey, Ph.D. in photobiology, at Newcastle University's Institute of Cellular Medicine. He has shown that, on average, the cheapest, poorest quality sunscreens allow three times more UVA rays to be transferred through the skin compared to sunscreens made from natural, non-toxic products.

This matters because UVA rays are more abundant than UVB, and UVA damage is more subtle than primarily UVB-induced sunburn. UVA rays can invisibly damage skin by suppressing the immune system and aging skin over time; overexposure to these rays is also linked to the development of melanoma, squamous cell carcinoma, and basal cell carcinoma.

Now, it is important to point out that there is no sunscreen that protects us 100%, especially if we spend many hours in the sun.Many contain harmful chemicals, and even mineral-based ones often contain nanoparticles, tiny ingredients that can cross the blood-brain barrier and are also harmful to the environment and marine life

That's why it's so important to look for safer sunscreens and recognize that you can't just rely on sun creams to prevent overexposure to the sun.

Because of this, experts recommend applying thick layers of sun protection, reapplying it every time you get out of the water, and choosing a natural and ecological product are the key to starting the change. But other methods to avoid overexposure are a must. In fact, sunscreen should be your last line of defense against the sun after other, more effective measures. Although it may not seem like it, a good diet without saturated fats and processed products will help our skin to be healthier and have a better response to sun exposure.

A dose of unhealthy hormones; Oxybenzone

  • Oxybenzone, a common ingredient in sunscreens, penetrates the skin, enters the bloodstream, and acts like estrogen in the body.
  • Oxybenzone has been detected in blood at levels 438 times higher than the recommended limit exposure rate.
  • Oxybenzone can remain in the blood for more than three weeks.
  • Oxybenzone has been linked to endometriosis in older women and lower birth weight in newborn girls.

Allergic reactions:

Chemical sunscreens often contain methylisothiazolinone, an ingredient that is linked to many allergies.

Skin cancer

Retinyl palmitate is a form of vitamin A.

Government studies show it could accelerate the development of tumors and skin lesions.

A false sense of security:

SPFs above 50 SPFs only refer to protection against skin-burning UVB rays.

UVA rays penetrate deeper into the skin and are more difficult to block with sunscreen ingredients that contain toxic substances.

Excess exposure to UVA rays:

– Suppresses the immune system.

– Causes the formation of harmful free radicals in the skin.

– In associated with an increased risk of developing melanoma

How to avoid these problems

Sunbathing is vital to good health because it helps the body create vitamin D. There are multiple ways to get vitamin D, but it is best to get it by standing in the sun or eating foods rich in vitamin D. In fact, sitting in the sun without exposure for about 10 minutes helps your body create approximately 10,000 units of natural vitamin D.

Vitamin D deficiency has been linked to certain cancers, autoimmune diseases, heart disease, depression, osteoporosis, and many other ailments, so getting enough is important.

Avoid overexposure during peak sunlight hours, wear sunglasses and sun-protective clothing and hats (Solumbra is a good brand). These things reduce the risk of sunburn without sun protection.

Benefits of zinc oxide to protect your skin from the sun and burns.

For more than 2,000 years, we have turned to zinc to help treat burns and wounds. Today, the benefits of zinc oxide are even more extensive, but if we look back (into the past), records show that zinc itself was first used in a skin lotion to help heal burns safely. natural called Pushpanjan.This was first described in ancient Indian medicinal writings around 500 BC.

According to the official publication of the International Association of Astronomers, today zinc oxide is a key active ingredient in many diaper rash creams, calamine lotions, mineral sunscreens (including some of the best sunscreens ), vitamin supplements, and acne treatments sold in pharmacies or prescribed by doctors.

What is zinc oxide?

Zinc oxide is made from zinc, a type of metallic element found in nature. Like other elemental metals, including iron or electrolytes such as magnesium, zinc is capable of carrying a certain electrical charge that provides it with special benefits within the body. The benefits of zinc affect different systems in the body, including the immune system, the digestive tract, the brain and the skin – where it is used as a type of “building block” important for protein synthesis, the creation of enzymes and metabolic processes

While zinc itself can be found in nature, zinc oxide does not occur naturally, but is created when zinc is chemically heated and combines with oxygen molecules. The two elements vaporize, condense and form a fine, white, crystallized powder that settles on the skin providing a protective layer. (3)

Recent advances in zinc oxide particle size have led to a significant increase in zinc oxide cream and zinc oxide sunscreen. Beginning in 2008, researchers created nanometer-sized zinc oxide particles, leading to a "revolution in sun protection and skin care." An advanced formula of zinc oxide is now able to be applied to the skin without leaving a thick, white film, opening the door to much wider acceptance of natural sun care products.

Zinc Oxide has been proven to have the following uses and benefits

  • Helps reduce skin inflammation associated with rashes, allergies, or irritation (including diaper rash)
  • Provides broad-spectrum sun protection that prevents burns (even on photosensitive skin)
  • Provide protection against skin cancer/neoplasms (basal cell carcinoma)
  • Improves wound healing and prevents bacterial infections
  • Assist in the recovery of burns and damaged tissue
  • Help treat acne breakouts
  • Reduces dandruff
  • Helps treat warts
  • Treatment of pigment disorders (melasma)
  • Prevents skin aging
  • Improving collagen synthesis and the formation of new connective tissue

The problem with most sunscreens is that the individual chemicals often work by blocking either UVA or UVB rays, but not both. This means that chemical sunscreen manufacturers need to combine several different formulas/solutions in one product to prevent burns from occurring. The more chemicals added, the more chance there is for negative reactions, allergies and irritation.

The ideal solution; zinc oxide formula with natural products

That's why we at Bionobo are committed to helping solve this problem and have designed a highly waterproof sun cream and facial stick that works with organic natural products without any harmful toxins

For this we have used, among others, Zinc Oxide that offers protection against “broad-spectrum ultraviolet rays” (UVA/UVB), which does not always occur with chemical sunscreens that only block one type of UV light.

In the past, zinc oxide sunscreens had a bad reputation for causing noticeable white streaks on the skin, a sign that the zinc was not fully absorbed. However, in recent years skin care technology has come a long way, and our cream has a microfine formula. Again, these tiny particles are considered safe.

The reliability and strength with which a product prevents burns will depend on the amount of zinc oxide used in the formulation. Zinc oxide percentages vary widely, and the final percentage will determine the “SPF” level of the specified products.

In sunscreens, the percentages of zinc oxide are usually between 25 and 35 percent.

The less zinc oxide used, the shorter the window when it comes to protection. Therefore, SPF 15 will last less time than SPF 30, which contains more zinc. That is why we wanted to create a protector for all those people who want to take care of themselves both inside and out. Remember that our skin is the largest organ in our body and absorbs everything we put on it, including sunscreen

Why the use of avocado oil?

The use of avocados dates back to 5000 B.C. The Aztecs, Incas, and Mayans spread the pulp of the fruit on their skin for use in cosmetic applications. The Mayans of Guatemala used avocado to prevent parasites and intestinal worms, and promote healthy hair growth. They obviously knew they were doing something right!

In a cosmetic use, avocado oil has many therapeutic properties such as anti-aging, detoxifying and regenerative. On the medicinal side, it has antibacterial qualities. When you think about the regenerative properties of avocado this is an ideal oil for anyone suffering from sunburn, eczema, dryness and rashes. We can see that there are many fabulous properties that make the use of avocado oil worthwhile.

Another important fact about avocado oil is that it has a natural SPF.Does that mean you should layer on guacamole and spend a whole day in the sun? Uhm… No! On its own, you wouldn't want to use avocado oil as a sunscreen, but when used in conjunction with other ingredients, avocado oil adds significant value to sunscreen products. Avocado oil can also treat damaged skin thanks to to its PFA (polyhydroxy fatty alcohols). Studies have shown that they can repair skin cells already damaged by UV rays.

We use avocado oil in our Sun cream and in our Zinc stick. Not only do they protect the skin from the sun's damaging rays, but they work great for relieving sunburned skin.
