Titanium Dioxide vs. Zinc Oxide
The only two FDA approved ingredients that sufficiently cover both UVB and UVA ultraviolet rays are zinc oxide and titanium dioxide. Make sure to look for one or both of these ingredients in your sunblock. For comparison of the coverage achieved by titanium vs. zinc, see my previous post Protection: Chemical vs. Mineral Sunscreens.
Nanoparticles are a hot topic lately. Both zinc and titanium can be made in small particles (>100 nanometers) and then even smaller particles (<100 nanometers). The advantage of nanoparticles is that they are smaller, which means your sunscreen goes on clear, rather than white. This is cosmetically advantageous for those of us that don't like looking like Casper the Friendly Ghost. However, some are concerned that because of their small size, nanoparticles may be absorbed into our bodies and reach the blood stream and brain. However, there have been no studies that prove the harm, or for that matter, the safety of nanoparticles. Currently, we have no good answer. Until we do, I generally try and steer clear of nanoparticles.

Ingredients to Avoid
When you are shopping for a sunscreen there are a few ingredients you really want to avoid. These include:
- Retinyl palmitate
The San Francisco Chronicle article states that retinyl palmitate is used in over 30% of sunscreens and it has shown to result in skin tumors in animals. We want a sunscreen that protects us from skin cancer, not one that accelerates it! Parabens and phenoxyethanol are icky preservatives widely known to be controversial ingredients. Fragrance, if not from essential oils, is an umbrella term for dozens of unnamed ingredients, which are not required on labels in order to protect trade secrets. However, third party studies have found numerous unsafe chemicals in fragrances. See this report on newswire. So make sure your sunscreen doesn't contain any of these nasties.
Good Ingredients to Look For
If you're going to be slathering it all over your face every two hours, it may as well have some stuff that's good for your skin, right? Look for: jojoba oil, borage oil and shea butter. Sun exposure generates free radicals, so keep your eyes peeled for antioxidants and free radical scavengers like green tea and astaxanthin.
Red raspberry seed oil has been shown to have an SPF from 30-50 in some cases. Therefore, finding a sunscreen with red raspberry seed oil in addition to zinc and/or titanium can potentially provide additional protection. One example of a sunscreen with red raspberry seed oil is Think Sport Livestrong sunscreen, which you can buy at their website. I've tried this one and it rubs in well, without greasy or chalky residue.
Another sunscreen with red raspberry seed oil is Green Beaver, which you can buy here. I haven't tried Green Beaver sunscreen myself, but reviews online say that it rubs on well, but is a little greasy. So it may be best for those of you with slightly dry skin.
I've saved the best for last! Marie Veronique Organics has a sunscreen with red raspberry seed oil high up on the ingredients list, not to mention all kinds of yummy nutrients for your skin to drink up (like green and white tea, sea buckthorn oil, carrot seed oil, apricot kernel oil and honeysuckle). There isn't a single ingredient that isn't beneficial for your skin in this elixir. You can snag a bottle from their beautiful website. It's available in clear and two different shades. The tinted versions go on like a tinted moisturizer, giving very light, natural coverage. It goes on like a dream, and I swear it made my skin look luminous.
Finding a sunscreen that satisfies ALL of these qualifications AND looks good on is quite the challenge. I know, because I keep testing them out in an attempt to find the one that blends the best. Some other sunscreens I've tried that go on without the greasy residue or chalky whiteness include Elemental Herbs zinc sunstick, which you can buy on their website. It smells like coconut and makes me feel like I'm on a beach in Bali. But for those of you that are particularly sensitive, it also comes in an unscented version.
website. Trukid also makes a bottle of cream sunscreen, which applies like a chemical sunscreen (it's that easy to rub in) and smells like mandarin oranges. So delicious! Get it on their website right here. What I love about Trukid is that they are so quick to respond to cosmetic safety reports. When the news on retinyl palmitate emerged, Trukid was the first to reformulate and come out with new sunscreens that didn't contain the icky ingredient. And you'll notice, if you head to their website, that they label their new product very clearly: "Now does not contain vitamin A." Just recently, they responded to my concern about including phenoxyethanol in their sunscreens and removed it! You don't know how jazzed I am that they did this! I just love the consistency of their sunscreens and now their ingredients are just dazzling.
