What is SPF Factor and how does it work?
SPF or Sun Protection Factor is a measurement of how well a sunscreen will protect the skin from UVB rays (the ultraviolet radiation that causes sunburn). Hence if your skin would normally burn after 10 minutes in the sun, applying an SPF 15 would allow you to stay in the sun for aprox. 150 minutes.
The SPF factor, however, is not a linear measure and is dependent on the skin type of the user. Furthermore, an SPF of 30 actually only blocs 5% more UVB radiation.
High-SPF products can create a false sense of security, and contain higher concentrations of allergenic or irritating ingredients and offer little additional sun protection.
In practice, for best protection, experts recommend a minimum of SPF15.
Sunscreen should also be re-applied after vigorous activity, and after swimming.
What is the difference between a physical barrier vs a chemical barrier sunscreen?
A physical barrier sunscreen (such as our Substance Sun Care products) physically blocks the sun's UV rays. These are often found in ingredients of titanium dioxide and zinc oxide.
Often, sun blocks containing these two ingredients have been messy and opaque. Substance Sun Care products however, uses micro ionized zinc. This we feel is the safest & most effective option. It creates the same physical barrier, but is more transparent, and less messy when rubbed in.
Physical barriers also have the added benefit over chemical sunscreen of blocking UVA rays. UVA rays penetrate deeper into the skin's surface, increasing the risk of cellular skin damage. Most chemical sunscreens do not block UVA rays effectively. The best-known and proven UVA protection is provided by products that contain zinc oxide.
Furthermore chemical sunscreens can be an irritant to sensitive skin. Zinc, on the other hand, has many beneficial properties including being anti-bacterial, and anti-inflammatory; beneficial to sensitive, delicate skin.
What are the differences between the two Sun Care Cremes?
In terms of its sun protecting, moisturizing, and skin-soothing properties, the Unscented Sun Care Creme is no different than our Natural Sun Care Creme. The only difference is that we have omitted our Essential Oil blend, for those who may have some sensitivities to scent. We do not use any artificial fragrances in our products. Please note that while our original scented formula acts as a natural insect repellent, our unscented version does not contain those same repelling properties.
Are the essential oils in the original Sun Care Creme safe for baby?
Yes all the essential oils in our Baby line are safe for babies. Essential oils have the value of not only smelling sweet and pleasant on babies skin (much more appealing than other synthetic fragrances used in over the counter sun care creams) but have the added benefit of being beneficial for you and baby! The essential oil blend in our Natural Sun Care Creme acts as a natural bug repellent along with helping to calm and soothe overexposed skin.
