Our SPF 15 Lip Balm uses a premium quality formula of organic ingredients paired with a natural zinc oxide mineral sunblock/sunscreen. And better yet, our lip balm formula uses non-nano particle zinc oxide which is the size you don't have to worry about.
Our Lip Balm is SPF rated at 15 and water-resistant rated at 80 minutes.
When researching our lip balm with sunblock formula we looked for one that has both an organic base and a natural sunblock. There are many natural lip balms on the market but the majority use chemical sunscreens. Others may use a natural mineral sunscreen like zinc oxide but then use petrolatum and/or artificial ingredients. You also find some zinc oxide and/or titanium dioxide sunscreens that also have oxybenzone and/or other chemical sunscreens mixed in.
Always read the labels.
Doesn't non-nano zinc oxide leave a white shadow Generally, yes, but for our formula to achieve an SPF 15 rating requires less zinc oxide in the formula and one particular ingredient (Polyhydroxystearic acid, only sounds scary, it is natural and safe) is added that suspends and disperses the zinc oxide evenly minimizing any white shadowing effect.
Think about it, if you're putting a lip balm with artificial ingredients and chemical sunscreens onto your lips, aside from the skin absorption you are also going to be inadvertently ingesting those ingredients. Our lip balm is all-natural and organic, it is non-toxic.
What about thickness The zinc oxide does make the lip balm consistency slightly thicker than SPF lip balms with chemical sunscreens but it still glides on smooth.
