Sunscreen: still the best weapon against skin cancer

The sun is a natural source of Vitamin D, but it can also kill us. As of today, the sunscreen still is the best protective weapon against UV A/B radiation.

If you enjoy outdoor activities and water sports, sunscreen is an essential health product because it will protect your skin against the sun's UV rays.

While the sun fuels your body with natural Vitamin D properties, it can also cause dangerous sunburns, and increase the risk of developing skin cancer and premature aging.

There's a lot of talk about the potentially harmful effects of sunscreen. The controversial debate mixes market share wars with empirical conclusions, and debatable scientific conclusions.

One thing is for sure: all sunscreens interact, positively or negatively, with your endocrine system, the chemical structure of your body that secretes hormones into the circulatory system.

In general, we could say that the majority of sunscreen products is safe to use. Of course, not all formulas are equal, and not all defend your skin as they should.

UV radiation: the penetration of UVA and UVB rays in our skin

There are two types of sunscreen - mineral-based and chemical-based - and they both form a physical barrier that scatters or blocks the ultraviolet radiation.

A chemical-based sunscreen typically includes chemicals like avobenzone, homosalate, octinoxate, octisalate, octocrylene and oxybenzone.

Oxybenzone is the most common sunscreen chemical. Some studies indicate that it may lead to endometriosis in women, and reduce sperm count in the male population.

However, oxybenzone is also one of the few ingredients that actually defends and protects your skin.

United States and Europe: Two Sides of the Same Sunscreen

But there are many more chemical ingredients included in commercial sunscreens that have been approved by the Food and Drugs Administration (FDA). They are as follows:

UVB | Chemical Absorbers

Aminobenzoic Acid
Cinoxate
Homosalate
Octocrylene
Octinoxate
Octisalate
Octyl Dimethyl
Phenylbenzimidazole Sulfonic Acid
Triethanolamine Salicylate

UVA | Chemical Absorbers

Avobenzone
Dioxybenzone
Menthyl Anthranilate
Oxybenzone
Sulisobenzone

Mineral-based sunscreens have their downside, too. Some of them are not chemical-free, and in some cases, ultra-small particles may enter your body and harm your body.

The FDA approved the use of two mineral ingredients in sunscreens:

Titanium Dioxide
Zinc Oxide

Sunscreen: there mineral and chemical-based formulas that block or absorb UV rays

Interestingly, the Europe authorities have set a wider filter and authorized the use of 12 ingredients that are not allowed in the United States. They are as follows:

Amiloxate (UVB)
Bemotrizinol (UVA and UVB)
Bisdisulizole Disodium (UVA and UVB)
Bisoctrizole (UVA and UVB)
Diethylamino Hydroxybenzoyl Hexyl Benzoate (UVA)
Drometrizole Trisiloxane (UVA and UVB)
Ecamsule (UVA)
Enzacamene (UVB)
Iscotrizinol (UVB)
Octyl Triazone (UVB)
Polysilicone 15 (UVB)
Tris-Biphenyl Triazine (UVB)

So, are sunscreens toxic? Will these chemical and mineral ingredients hurt the human body?

Hundreds of scientific studies and academic analysis have been carried out already, but the results are often inconclusive. That said, the occasional use of sunscreens still is the best weapon against skin cancer.

And forget the natural formula missionaries - coconut oil is not an effective UV blocker.

Finally, remember that the clothes are always the most powerful protection against the harmful effects of the sun. If you're going out to the beach, or surfing, make sure to use a good, high-protection protection sunscreen.

According to the American Academy of Dermatology, you should apply sunscreen 30 minutes before getting exposed to the sun because it takes around 15 minutes for your skin to absorb the UV radiation.

If you have children, and although no scientific evidence proves its harmful effects, try to avoid sunscreens with oxybenzone.
