People use sunblock and sunscreen to prevent skin cancer and sunburn. Unfortunately they are often made by big corporations and companies that sometimes do not have the safety of the product as their primary concern. We could compare them to tobacco industry. Many are funded by the pharmaceutical companies that are also making money on cancer medications.

Although sunblock and sun screen sound similar they work in different ways. First lets look at how those two work and what are their ingredients. Later on you will discover the 8 most common natural tanning oils.

Sunblock physically blocks the sun from contacting skin. Common active ingredients in them are titanium oxide or zinc oxide. These both ingredients can come in the micronized form or as nanoparticles. They are both derivate from the minerals (titanium and zinc). Since the use of the nanotechnology is still young there hasn’t been any long-term studies done to prove if they are safe to use or if they lead toxicity.


However there have been a couple studies suggesting that with the exposure to the UV rays some nano particles break down and get absorbed in skin creating free radical damage, may be creating brain damage, cause cancers and damage DNA.

Sunscreen filters UV rays from the sun but allows some of them to penetrate the skin. Common ingredients in sunscreen are:

– Oxybenzone which may cause eczema like allergic reactions and experts also suspect that it disrupts the bodies hormones
– Octinoxate which does disrupts hormones, also promotes premature aging andit produces free radicals that are damaging the skin and cells.
– Retinyl Palmitate, an antioxidant… however when exposed to the sun’s UV rays, retinol compounds break down and produce destructive free radicals that are toxic to cells, damage DNA, and may lead to cancer. In fact, FDA studies have shown that retinyl palimitate may speed the development of malignant cells and skin tumors when applied to skin before sun exposure
– Octocrylene, when this chemical is exposed to UV light, it absorbs the rays and produces oxygen radicals that can damage cells and cause mutations. To make things even worse once it is absorbed by the skin it accumulates in the body.
– Paraben Preservatives associated with both acute and chronic side effects, parabens (butyl-, ethyl-, methyl-, and propyl-) can induce allergic reactions, hormone disruption, may contribute to the breast cancer, developmental and reproductive toxicity.

Not only are both sunblock and sun screen a cocktail, full of hormone disrupting, cell damaging, cancer creating ingredients but they also block vitamin D from being absorbed in our body.

Vitamin D, as recent studies have shown, prevents up to 77 of ALL cancers in women including breast cancer, colon cancer, cervical cancer, lung cancer, brain tumors, multiple myeloma… you name it!.

If sun creams are so bad how can we protect ourselves from harsh UV rays and prevent skin cancers?

Use sunblock (not sunscreen) that is oxybenzone free, retinyl palmitate free, nanoparticle free and provides maximum SPF 50. The best ones are made of zinc oxide because it is not made of nono particles and therefor does not penetrate the skin entering the blood.

Eat a diet that consists a lot of antioxidants that reverse the damage from free radicals in body, algae rich in astaxanthin that can act as an internal sunscreen and omega 3 which protects your skin against sunburns.  Obviously sun baking is not recommended but being exposed to sun without sunblock for 20 min every day is beneficial to boost vitamin D production in your skin.

Use natural tanning oils to protect your skin! Most of them are rich in vitamins and natural essential fatty acids. You need to test these to find out which is the best for your skin: avocado oil, coconut oil, green tea extract or aloe vera, hazelnut oil, olive oil, wheat-germ oil, sunflower oil, sesame oil.
