Skin sensitivity: You may be sensitive to -- or even allergic to -- some of the chemicals in the sun screen you're using. This is not uncommon. Possible culprits may be ingredients like paba and benzophenones -- one of the most common causes of sunscreen-induced contact dermatitis. Check your labels and see what's in the stuff you're rubbing onto your skin. Zinc oxide and titanium dioxide may be less irritating. ...Read more

Sunscreen: Typically it is best to apply sunscreen after any and all topical medications. Applying medications over sunscreen can reduce the effectiveness of the sunscreen putting your skin at risk for sun damage. It is perfectly fine to apply medications and then sunscreen as this order will not disrupt the effectiveness of the topical medications. ...Read more
What do the SPF numbers on sunblock/sunscreen mean? How do I know what the right amount of SPF is for me?
Sunprotection factor: Spf means sun protection factor and is a measure of the amount of protection from the sun a sunscreen provides. So the higher the spf the more protection it gives from the sun and the longer you can stay out after application. It is difficult to say exactly how long you can stay out based on the spf only as it depends on sun intensity. So the higher the spf the better generally speaking. ...Read more
I don't want to get darker so I bought SPF 50 sunscreen but some people told me that sunblock makes you not get darker. Is that true?
SPF 30, broad spectr: An spf of 100 does not provide that much additional benefit over spf 30 sunscreen. The important thing about sunscreen is that you actually use it, reapply it, and that it is broad spectrum. ...Read more
Supposing I'm using sunblock SPF 50, how much sunblock should be applied on the face daily for effective protection?
Once before going...: Applying sunblock each day, once before going outdoors, should be adequate if the sunblock is not washed off. If there is a lot of sweating, face-wiping, rinsing, or washing, then nobody really knows how much sunblock is remaining on the skin. In that case, one can apply again sunblock while the sun is still bright. ...Read more

If I put sunblock cream (spf 50 or 100) on my skin and expose my body to the sun, will I get vitamin d normally?
No: When the sun's uv b rays hit out skin, we turn inactive d to active vitamin d. So if you are wearing sunscreen that blocks those rays, then your body will not perform this process and you could be at risk for vitamin d deficiency. You can get a blood test to determine your vitamin d levels. ...Read more

Alot of people put sunblock on when they're outside instead of putting it 15 minutes before going outside. Which way is better and does it matter?
Before: Sunblock is more effective when applied prior to exposure. Depending on skin type, it doesn't take long for the damage to be done. Some people may start to burn after just 10 or 15 minutes. Sunblock also needs to be reapplied often (every 2 hours) and after swimming even though it says, "waterproof." make sure to use a sunblock that protects against uv a and uv b. ...Read more
Titanium Dioxide: Titanium is one of the physical sun blocking agents found in certain sunscreens. I recommend the physical blocks (zinc and titanium) because they have a very good safety profile and work very effectively. If you are going to be in the sun - use a minimum of SPF 15 - follow product directions. ...Read more
Block UVA & UVB: An ideal sunscreen would block both uva & uvb rays with active ingredients that do not break down in the sun (so that the product remains effective), and would contain active and inactive ingredients that are proven to be safe for both adults and children. Unfortunately, there is no sunscreen that meets all of these criteria, and no simple way for consumers to know how well a given product stack. ...Read more
Using sun screen has several benefits
first, it can prevent sun burn which can be very painful
more importantly, most forms of skin cancer are caused by an accumulation over time of the suns harmful ultra violet rays. Some of them can be deadly
in addition, too much sun exposure over time causes the skin to be rough and wrinkled. ...Read more
Both are great: Sunblock normally consists of a physical blocker like zinc or titanium oxide which block and reflect both uva and uvb rays. Sunscreen usually means a chemical screen that interacts with the uvb rays to prevent sun damage. A combination of both us very common, but for very sensitive skin, a block is sometimes better. ...Read more
Shield vs filter: True sunblocks essentially create a shield to effectively block out the sun with zinc oxide being one of the most common preparations. They tend to be opaque. Sunscreens are chemical agents which filter out undersireable wavelengths of the sun and come in a variety of strengths and formulations. They tend to be clear. The diagram represents the spectrum of coverage. ...Read more
Nope: Sunscreens work via 2 possible ways: 1) chemical blocks that breakdown the uv rays as they pass through the skin and 2) physical blocks that prevent the uv rays from getting to the skin. I recommend the physical blocks (zinc and titanium) because they have a very good safety profile and work very effectively. If you are going to be in the sun - use a minimum of SPF 15 - follow product directions. ...Read more
None: Both do the same thing in blocking out rays of sun. ...Read more
Sunscreen/sunblock: The difference between is how good they are at screening out harmful radiation from the sun. Blocks are stronger and thus more effective at keeping out those harmful UV rays. Blocks are also usually more visible. For instance, the white zinc oxide life guards use on their nose is more of a block. Nothing is 100% though, so hats with wide brims and lightweight clothing works well too! ...Read more

How can I convince my kids to wear sunscreen/sunblock? Any tips (anything would be appreciated, please!)?
Just do it: Your children are not in control of their lives-you are. When you put them in a car seat and buckle them in it is to protect them from injury. Sunscreen is no different and can be just as life saving. I have a father-in-law with end stage melanoma. His mother didn't use any sunscreen. Make the decision now to do what's right for your children. Someday they'll understand the love behind the lotion. ...Read more
Which is best sunblock available which protects whole day? Is it necessary to buy new sunblock every year?
Zinc / Titanium: Sunscreens work via 2 possible ways: 1) chemical blocks that breakdown the uv rays as they pass through the skin and 2) physical blocks that prevent the uv rays from getting to the skin. I recommend the physical blocks (zinc and titanium) because they have a very good safety profile and work very effectively.

Chemical: You must be referring to a chemical sunblock, since it is a topical skin product. Nivea has multiple different products, some with sunscreen and some without.
