Why sunscreen can be a factor in dealing with UV light?
UV stands for Ultra Violet, and UV light is harmful to your skin if your skin is exposed for long enough. Sunscreen tends to block, absorb, or reflect UV rays, therefore protecting your skin. The strength of the sunscreen can differ, and that's why you see labels on sunscreen bottles saying "25 SPF" or "35 SPF", the higher numbers indicating stronger sunscreen for longer or more intense exposures.

Would adding spf 30 sunscreen to spf 50 sunscreen make it spf 80 sunscreen?
No. SPF 30 lets in 1/30 of burning UV rays, while SPF 50 lets in 1/50. Adding the two together is pointless and would not result in high levels of skin protection.
What does SPF 45 mean?

What is a good spf sunscreen for kids?
4, 15, and 30 are good Sun Protection Factors for kids as they contain no "Bad Ingredients". SPF 50+ should not be used on young children. SPF 100+ can not be used on children under 13.
How does sunscreen works?
Sunscreens work by absorbing, reflecting or scattering ultraviolet light, thereby reducing the amount that reaches the skin. The sun protection factor (SPF) of a sunscreen tells you how much longer you can stay in the sun without burning if you apply the sunscreen. For example, if your child would burn after 20 minutes of sun exposure, applying a sunscreen with a SPF of 15 gives her 15 times the protection. In this example, the child will be protected for up to 5 hours: 20 minutes x 15 SPF = 300 minutes (5 hours). The FDA recommends that kids use a SPF of 15 or higher to prevent both sunburn and tanning. A SPF of 15 will block about 94 percent of UVB rays and a SPF of 30 will block about 97 percent of UVB. But keep in mind that these SPF ratings do not necessarily mean your child will be protected against the UVA rays that cause cancer and skin damage. SPFs only give a rating of sunburn protection. Your sunscreen should include ingredients that protect against both UVA and UVB rays.
How is SPF rated?
The SPF system was developed in 1962 by Franz Greiter to measure the capacity of a sunscreen to block UVB radiation. The rating of the system was determined based upon how long it took skin to redden or burn without sunscreen. An example is it takes approximately 20 minutes without sunscreen for your skin to turn red. With an SPF-15 cream, it would ideally take 15 times longer for the skin to turn red.
Why should you protect your skin?
A person should protect their skin to decrease chances of getting skin cancer. One way of protecting your skin is by wearing sunscreen of at least SPF 15, depending on where you reside. A person should also moisturize and properly hydrate their skin to decrease chances of skin dehydration.
