Natural Sunscreen


SUNSCREEN: I get some sun everyday and then cover up rather than slather up (with sunscreen!) - but I think I may have found a safe, natural sunscreen for when needed: Mexitan. I was looking at Greenlight (magazine) and checked on one of their biodegradable sunscreens' ingredients. Mexitan has Active Ingredients: Titanium Dioxide, Zinc Oxide and Inactive Ingredients: Sunflower Oil, Green Tea Extract, Coconut Oil, Almond Oil, Lanolin, Tocopherol Acetate(Vitamin E), Eucalyptus Oil, Ascorbyl Palmitate(Vitamin C)

I had questions about when the minerals (titanium or zinc oxide) are too small to be safe, and can enter your tissues and bloodstream if too small,and noticed Mexitan's website asserts they have no nanoparticles. Here is Mexitan's reply:

Thanks for your question. It is one we get a lot these days with people concerned about nanoparticles. The short answer is that Mexitan does not contain any nanoparticles.

The technical aspects of our stuff is as folows. The titanium dioxide and zinc oxide used in Mexitan is micronized (NOT nanoparticles), with a coated variable particle size greater than 100nm but less than 500nm. (Nanoparticles are considered to be less than 100nm in size). This allows our sunscreen lotions to be more cosmetically appealing compared to coarser particles. The protection is less visible, yet remains on the skin's surface.

....Thanks for your interest.

This looks pretty good.

Over the weekend my husband and I went kayaking and needed some sunscreen so our skin wouldn't burn being out in the sun on a three-hour trip. We had to buy whatever we could find at a chain drug store and were pleased to find Neutogena Sensitive Skin Sunblock Lotion. It also contains titanium dioxide, though the inactive ingredients are not natura, and it is unscented. It went on white, so no nanoparticles. While not the best, it was nice to know there was at least a better choice at the drug store!

Still, I want to caution that there are some health concerns about titanium dioxide so I suggest using it as needed, and not just applying it every day. Better to block sun with umbrellas or clothing or stay in the shade when you can.

Hi Debra,

The ONE Group, manufactures of the Miessence products have just come out with a sunscreen. I am not generally a user of sunscreen but I'm glad that this option exists now.

The zinc oxide is also micronized in this product and there is NO Titanium Dioxide.

It has also been evaluated by EWG on their website skin deep:

The product was 2.5 years in the making, you can view a short clip about it as presented by Narelle Chenery the product formulator here on utube:

Reflect Outdoor Balm: stated SPF is 15, it has been tested up to 29.5 SPF


organic olea europae (olive) fruit oil, zinc oxide, capric triglyceride (coconut), organic butyrospermum parkii (shea) fruit butter, organic unrefined cera alba (beeswax), avena sativa (oat) kernel flour, polygonoum multiflorum root extract, d-alpha tocopherol (natural vitamin e), organic copernicia prunifera (carnauba) wax, aroma (essential oils), rosmarinus officinalis (rosemary) leaf extract, dunaliella salina algae extract.

If anyone is interested in the product it can be purchased on my site:

Miessence Certified Organics

Earth Friendly Products


Hi Debra,

It seems that Miessence Certified Organics representative indicates that their sunscreen has "micronized" zinc oxide. I think this is the same as nanoparticles? If it is doesn't this seem to contradict the previous two posts which underscore the use of NON nanoparticles (albeit titanium dioxide)?



COMMENT FROM DEBRA: Here's the response from Erin (the MiEssence rep) on this.
I don't have the exact size for the zinc oxide particles in the sunscreen, I will have to work on getting that information.

It is my understanding that Micronizing is the process they use in nanotechnology to break the particles down to smaller size. There are different sizes for the particles, they can be micro size or nano size but the actual process is called micronizing.

The reason why a company would want to make the particle size smaller is so the zinc oxide does not appear white on your skin when you use the product. When I was a kid, I used straight zinc oxide on my nose and you would see everyone walking around with white noses back then. So, if you do not want to walk around like a ghost, then the particles have been made smaller so they appear to not show up like the white gunk of our childhood days.

It is my understanding that the size of a micro particle is not small enough to pass through the skin, but still small enough that it does not appear completely white on your skin when you apply it.

I do not know the exact size of the micro particles in the Miessence sunscreen but I will check in to that and get back to you when I find out. It may be next week before I can answer that question.

Here are a few posts on the EWG website where people can read more about sunscreen and the ingredients including nanoparticles:
* My sunscreen says it has nano particles in it, should I be concerned?
* Sunscreens Nanotechnology Summary


More from Erin:
This from Miessence...
Nanoparticles are defined as being smaller than 100nm. The zinc oxide in Reflect is 150nm.
