The Thinkbaby Safe Sunscreen Stick is highly effective, falls into the highest category for water resistance (as defined by the proposed 2012 FDA Sunscreen Monograph) and has a sensible SPF 30 rating. A quick look on your local drugstore shelf will show an increasing number of chemical sunscreens boasting ultra-high SPFs of 70 and greater. An SPF higher than SPF 30 offers only minimal improvement in sun protection and does not provide insight into its ability to protect for both UVA and UVB. Instead, these ultra-high SPFs are inflated through the use of chemical UV absorbers. In the 2012 Sunscreen Monograph, the FDA proposed that SPF 50+ will become the maximum value. The proposed Monograph will also eliminate the terms "Sweatproof" and "Waterproof" as false claims.
You should know that the effective difference between SPF 30 and SPF 100 is approximately 2.5% difference. Don't be misled by ultra-high SPF numbers. Additionally, Thinkbaby and Thinksport sunscreens utilize average zinc oxide particles greater than 110nm. Kevin Brodwick, founder of Thinkbaby and Thinksport explains why: "We always use the precautionary principle and as we expect the debate on the safety of nano particles to continue, we asked a simple question: Does the product have to contain nano particles to be an effective sunscreen? The answer is, quite simply, "NO"!
We also do not and won't use aerosol dispensers, nor should you. Scientists have shown that parents apply on average 25% of the correct amount when using aerosol. As the SPF is actually a logarithmic function, if you are applying a SPF 100, you're actually only putting on SPF equivalent of 3. More importantly, there is significant concern that children and parents are inhaling the particulates. If you look at the ingredients in aerosol sunscreens, you'll quickly determine why you probably don't want to breathe it.
