- Apply at least every 60-80 minutes and reapply after swimming or rigorous activity.
- Mineral-based sunscreens take immediate effect; there is no lapse time between application and effectiveness

SUN PROTECTION MEASURES: Spending time in the sun increases your risk of skin cancer and early skin aging. To decrease this risk, regularly use a sunscreen with a Broad Spectrum SPF value of 15 or higher, limit time in the sun, especially from 10 am-2 pm and wear protective clothing and sunglasses.
What is SPF Factor and how does it work?
SPF stands for Sun Protection Factor. It’s a number that you can use to help determine how long you can stay in the sun before getting a sunburn.
The SPF is a multiplication factor. If you can stay out in the sun 15 minutes before burning, using a sunscreen with an SPF of 10 would allow you to resist getting a burn for 10 x longer or 150 minutes.
The SPF factor, however, is not a linear measure and is dependent on the skin type of the user. For example, an SPF of 30 only blocs 5% more UVB radiation than an SPF of 15. Another way to look at it is in terms of percentages: SPF 15 filters out approximately 93 percent of all incoming UVB rays. SPF 30 keeps out 97 percent and SPF 50 keeps out 98 percent.
In practice, for best protection, experts recommend using an SPF15 or SPF 30 as a higher factor does offer a significantly higher level of protection than an SPF of 30.
How should sunscreen be properly applied?
To ensure that you get the full SPF of a sunscreen, you need to apply 1 oz – for full body coverage. Studies show that most people apply only half to a quarter of that amount, which means the actual SPF they have on their body is lower than advertised. Reapplication of sunscreen is just as important and it is recommended to re-apply sunscreens every 2 hours. Sunscreens should also be reapplied immediately after swimming, toweling off, or sweating a great deal.
What is the difference between a physical barrier vs a chemical barrier sunscreen?
A physical barrier sunscreen (such as our Sun Care for Baby) 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 Cream, however, uses micro-ionized non-nano zinc oxide. 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
