Peak Testosterone has already given some coverage to many of the nasty,
toxic chemicals in sunscreens in my link on The Dangers of Sunscreens.
Again, we cannot help but be amazed at the irony of supposedly cancer-protecting
products actually likely causing cancer and other health problems. As always,
you have to protect yourself: you cannot trust most companies to have your
long term health in mind.
The good news is that there are now a significant number of sunscreen
alternatives available now that should have a much better safety profile. Some
companies (with an apparent corporate conscience) have jumped in and prepared
excellent sunscreens without most of the known, toxic offenders. These
sunscreens, for example, leave out the avobenzone and oxybenzone, whose likely
toxicity I covered in the above-mentioned link on
The Dangers of Sunscreens. These two
ingredients are in most sunscreens and, until recently, it has been almost
impossible to avoid them.

Before we look at a couple of the sunscreens that have made a real effort to be a
more "natural" and safe alternative, there are a couple of other potentially
toxic ingredients that we should mention:
1. 4-MBC (4-Methylbenzylidene camphor ). This endocrine disruptor is a
xenoestrogen  and possible thyroid disruptor.  It also has some UVA
blocking capabilites so some manufacturers add it to the ingredients.
2. Retinyl Palmitate. This is a controversial compound. The
Environmental Working Group submitted a paper to the FDA summarizing many
studies that show that this compound releases reactive species (free radicals)
when exposed to sunlight. Furthermore, animals developed significantly
more tumors at fairly reasonable doses of both sunlight and retinyl palmitate.
 Other researchers have argued that the data is inconclusive, since retinyl
palmitate is a natural vitamin A derivative and the product has been used for
years in cosmetics without any major issues. 
Most of the popular sunscreens (in the U.S.) have at least 3 of these likely
toxic ingredients (avebenzone, oxybenzone, 4-MBC or retinyl palmitate).
So are there any decent sunscreen alternatives? Are there any sunscreens that may
actually protect you from skin cancer instead of helping to induce it?
Below are some brands that I have tried with good success:
1. Mexoryl Anthelios. Mexoryl products, while not cheap, are widely used in
Europe. To date at least, it is a chemical sunscreen with none of the major
issues of the other chemical sunscreen active ingredients.
Anthelios Xl SPF 50
2. Aubrey Natural Sun. This brand avoids the chemical ingredients
altogether and relies on good ol' zinc oxide instead. Of course, the
problem with zinc oxide, especially for light skinned folk, is that zinc
oxide can create a ghostly effect and actually highlight wrinkles. However,
15 Active Lifestyles uses a variety of oils and extracts in the
product that almost completely mask these effects. NOTE: Other Aubrey
sunscreens with zinc oxide do not have this same property. Again, my
advice is to stick to Active Lifestyles if you're a low pigment sort of guy.
3. Alba Botanica. Another very similar product is Alba Botanica Mineral Sunscreen.
This sunscreen relies on zinc oxide and titanium dioxide, both sunblockers and
not synthetic chemicals sunscreens, for UVA protection.
I mention this product, because it is easily the least expensive alternative
that I have found. However, if you are fair-skinned, it will likely give
you somewhat of an early 90's Goth
