The Difference Between Physical and Chemical Sunscreens
Physical (or mineral) sunscreens work by protecting the skin with a physical barrier on top of the skin. Mineral sunscreens contain an active ingredient of either zinc or titanium oxide. Thinkbaby™ sunscreen has the active ingredient of zinc oxide. Chemical sunscreens penetrate the skin and are absorbed into the blood stream. Active ingredients such as oxybenzone are found in chemical sunscreens and can act as endocrine disruptors in the body.
The Truth About SPF Ratings
Thinkbaby and Thinksport™ sunscreen is rated SPF 50+. The American Academy of Dermatology recommends children over 6 months and adults use a sunscreen with SPF of 30 or higher. Some chemical sunscreens advertise SPF ratings as high as 100, however, the FDA revisited the system and set the upper limit to SPF 50 for 2012. The rating system as it stands causes more misperceptions than it solves. In short, sunscreens with very high SPF ratings do not provide better protection than a SPF 30 in relative terms. It's important to note that the current SPF rating system does not rate UVA; it only rates UVB. Dermatologists recommend using a broad-spectrum sunscreen that protects against both UVA and UVB exposure. UVB is what commonly is associated with causing sunburn and free radical generation. Where UVA has been linked to skin damage and even more serious potential for free radical generation.
In sunscreen, nano particles refer to 0 micron to 1 microns or 1 to 100 nanometers. We acquire 100> nm size zano. There is concern within the scientific community that very small particle sizes may affect biological processes. Nanoparticles can easily pass through the epidermis and therefore could interact at the cellular level. To our knowledge there hasn't been any direct statements that have concluded what sizes are safe and which are not. But in the general category of nanoparticles there is concern not just for babies but their general use. They could have the potential for greater disruption for infants, whose bodies are going through significant development. This is the same concern that scientists have in relation to what harmful chemicals pose on infants. The challenge surrounds on how to do testing. It certainly wouldn't be advisable to conduct testing on babies or animal studies. So they will have to be done on cells to see their potential to interact and then we'll have to extrapolate whether there would be similar concern within our biological systems. We can only theorize at this point that very small particles could disrupt cellular mechanisms that are very sensitive. There is not significant enough research to conclude that nano particles are safe. You will not find a legitimate researcher to agree that there is enough knowledge at this point and the testing is complex. We specifically utilize larger particle zinc oxide.
We do not test on animals. Ever. Period. And we will not work with any entity that does. Period.
