That's it!
No need for oxybenzone, or octinoxate, or the common sunscreen preservative methylisothiazolinone (named “allergen of the year” by the American Contact Dermatitis Society).
So if I create the recipe that my customers approve of, and follow the SPF requirements set by the FDA, I’ve got the perfect product, right?
Not so fast, Surfer.
(Don't give up hope, though. You can use our Simply Soothing Rash Cream in a pinch because the ingredients are all there... it's on YOU to make sure you don't burn.)
I dove into the research with the hope of having something ready for you to buy (this was back in 2015).
Here’s what I found about safe sunscreen regulations:
Prior to 2012, FDA regulations for sunscreens dealt almost exclusively with protection against sunburn, which is primarily caused by ultraviolet B (UVB) radiation from the sun. Now the FDA regulates for warnings about skin cancer and early skin aging as well, which is contributed by ultraviolet A (UVA) radiation. When you read a sunscreen label offering “broad spectrum” sun protection, that product has been tested for both UVB and UVA.
If I wanted to sell a sunscreen online, here’s what I would need to do:
I would need to send in a batch of sunscreen to be tested at an FDA approved test facility. I checked around and found that these cost several thousand dollars. This shouldn’t stop the savvy business person if there’s a good return on investment, but…
Testing one batch does not mean automatic approval. I would have to send in batch after batch, and pay for each one, until one was approved. Ouch. That would require some serious leg work first, which can be done… but what about the hiccups like…
Blending zinc oxide into your batch of sunscreen does not mean that the zinc oxide is equally blended throughout the cream. This is something to consider when you make it at home. Although you may have a fairly consistent blend, your SPF could vary (albeit slightly) within the same batch of sunscreen. There’s a risk with each batch. Bwaaah… back to the drawing board, or investing in a very powerful blender.
Zinc oxide is zinc oxide, which does leave a bit of whiteness on the skin. The more zinc that is blended in, the higher the SPF, but who wants to look like a ghost? While I might be fine with an SPF of 15, someone else might insist on a 50, which brings on an even greater amount of FDA regulation. It comes down to what my customers want…
Finally, there’s the whole waterproof claim. Even if I could prove the sunscreen is waterproof, the FDA does not allow me to say that it’s waterproof. I can’t call it sunblock, either. I could call it water resistant, if I’m willing to test the length of time the sunscreen is water resistant, and pay for that test, too.
And so, while I used to make sunscreen for our family, now I just grab our Simply Soothing Rash Stick and keep that handy. If you do make your own, remember about the blending aspect of it (#3 above). When you make sunscreen, you are making it at your own risk. As always, be aware of the dangers of overextended exposure to the sun and cover when necessary… with clothing, or sunscreen.
A Safe Sunscreen Company I Recommend:
While I use our Simply Soothing as a back-up, if I know I'll be at the beach for an extended period of time (especially in the beginning of the summer), I pack my 3rd Rock Sunscreen. I love the smell, it acts somewhat like a lotion, and it's extremely effective. Find it here (affiliate link) and/or read my experience with it here.
