There is a common misconception that all sunscreen is roughly the same and will do the same job. There are a variety of ingredients in sunscreens, however, and they may protect against different levels of sun exposure.
Active ingredients such as titanium dioxide, zinc oxide, and ecamsule are often used to filter out UVA and UVB rays. There are also chemical blockers, such as avobenzone. These ingredients all block the sun in different ways.
Using a full spectrum sunscreen is important because it will protect the skin against the largest range of UV light.
The other important consideration is the sun protection factor (SPF). The United States Food & Drug Administration (FDA) recommend regularly applying a sunscreen with an SPF of 15 or higher, even on cloudy days.
Many people think that sunscreen will last all day after just one application. In reality, sunscreen breaks down in the light and loses its effectiveness over a short period of time.
People should apply sunscreen every 2 to 4 hours, at least.
Sunscreen labeled as water-resistant or sweat-resistant, or marketed as sunscreen for sports, may appear to be waterproof. Unfortunately, this is an overstatement of what sunscreen can do.
No sunscreen product can be 100 percent waterproof. People must always reapply water-resistant sunscreens after water exposure. Allow sunscreen to settle on the skin for at least 10 to 15 minutes before going in the water.
Contrary to common belief, sunscreen naturally expires. The active ingredients can break down over time, and using expired sunblock may leave the skin unprotected.
Understanding the truth about these myths can help people use sunscreen effectively.
Instructions for each sunscreen can vary, and people should follow the instructions on the packaging for maximum protection. Proper use of sunscreen can help guard against skin damage and sunburn.

From doorbells to leak detectors and beyond, these smart gadgets will help you feel safer at home.
There are tons of smart devices out there today, promising to make your home more secure. They include home security systems, smart doorbells, connected leak detectors and beyond. But don't get bogged down by all of the choices.
Here's a rundown of gadgets that keep an eye on your house and your stuff so you aren't surprised by a break-in or a potentially damaging water leak. Note that CNET may get a share of revenue from the sale of the products featured on this page.
Read more: How do home security systems handle your privacy?
Home security systems like the DIY SimpliSafe kit pictured above, give you control over your home. Not only can you install and configure SimpliSafe yourself in the app, you can also monitor it yourself. Get alerts telling you motion -- or another type of activity -- was detected and decide what to do from there.
You can also sign up for professional monitoring if you'd like a remote team to keep an eye on things for you.
Additional home security systems that offer this functionality include: Ring Alarm, Nest Secure and Abode.
We've reviewed dozens of indoor home security cameras. While many offer different designs and prices, they all do roughly the same thing.
The $120 Amazon Cloud Cam has live streaming, motion detection and integration with Amazon Alexa. Amazon's Cloud Cam comes with free 24-hour video clip storage and an optional Cloud Cam subscription service starting at $7 per month.
Select other home security cameras, like the Nest Cam IQ Indoor, offer facial recognition and other advanced features.
Outdoor cameras are a growing category in home security. Like indoor cameras, they offer live streaming, motion detection and access to saved video clips.
You can install them pretty much anywhere your Wi-Fi network will extend -- near your front door, along a fence line or next to your garage. They help protect the perimeter of your home, alerting you to activity that happens outside.
The Arlo Pro 2, pictured above, is an excellent, battery-powered outdoor security camera. Others include the Nest Cam IQ Outdoor and the Ring Stick Up Cam Wired.
Smart doorbells, like the Nest Hello, perform a unique function within the outdoor security camera category. Part doorbell, part security camera, smart doorbells send alerts to your phone whenever it detects motion -- or whenever someone rings the bell.
You can then pull up a live video feed and chat with whoever's at the door. Tell a solicitor you aren't interested, instruct a delivery person to leave the package by the door and more. Select doorbells, like the August View, also work with smart locks, meaning you can talk to your visitors and unlock the door to let t...
There's more to keeping an eye on your home than security. Smart leak detectors alert you to a potential leak in bathrooms, basement, laundry rooms -- and any other places of concern.
Models like the Roost leak detector pictured, pair with a related app and send alerts to your phone when they sense water. It's a simple way to track areas prone to flooding and could save you a lot of money in the long run.
Smart smoke and carbon monoxide detectors are another good way to monitor your home's safety. Like the leak detectors, connected smoke alarms have related apps where you can check in on the status of your home.
You can get alerts telling you there's a potential issue, too, so you can contact your local fire department, even when you're away from home.
The Nest Protect and the Halo+ are two solid smart smoke and carbon monoxide detectors.
Connected garage door openers like the Chamberlain MyQ Garage, are a great way to track whether your garage door is open or closed.
These devices are fairly simple to install and have related apps so you can control and monitor the status of your garage door remotely. The Nexx Garage is also a solid option and it works with Alexa and Google Assistant without assistance from IFTTT.
Part-time officers are not required to be certified by the Tennessee Peace Officer Standards and Training, or P.O.S.T. Commission. They also do not have to complete a law enforcement training academy.
It's been more than two weeks since 20-year-old Shelby Comer was found shot dead inside of a car off of B Mine Road in Grundy County and TBI agents still won't say how Shelby died.
Comer was found shot to death inside a Ford Mustang two days before Christmas. That same car was pulled over earlier in the day.
The driver, 32-year-old Jacky Bean, is accused of pointing a firearm at the part-time deputy who pulled him over and hitting his police cruiser.
Officials say the Mustang was facing the deputy's cruiser at the time it took off towards the deputy, who fired several times into the car, before it sped away.
Channel 3 has since learned the part-time deputy who fired the shot that may have hit Shelby Comer, did not receive police academy training.
Sheriff Clint Shrum says Deputy Mike Holmes, as a part-time officer, is not state certified, but is still in compliance with state standards.
"Just because a person has not gone to that training academy does not mean that they're not qualified to work as a deputy or police officer part time," said Sheriff Clint Shrum.
Holmes was trained by the Grundy County Sheriff's Department and he's the department's only part-time deputy. Shrum employees 17 full time officers.
According to state standards, part-time deputies can work 20 hours a week and not more than 100 hours a month, unless on special temporary assignment.
Part-time officers are not required to be certified by the Tennessee Peace Officer Standards and Training, or P.O.S.T. Commission. They also do not have to complete a law enforcement training academy, but Shrum says that makes them no less fit to serve and respond.
"The word uncertified you know scares people and they think well you know they'll just hire anybody, but I guarantee you this, there is a ton of uncertified, part time, auxiliary, reserve deputies across this state," said Sheriff Shrum.
Part-time officers must complete at least 80 hours of initial training with the county that employees them and another 40 hours of in-service training each year. Certified full time officers attend an initial 12-week law enforcement academy then complete an annual 40 hours of in-service training each year.
The county would not allow us to inspect Holmes' personnel file, citing the on-going TBI investigation into the shooting, but Shrum says all officers are required to meet a list of minimum qualifications.
"We don't just have a part time guy running around with a gun on, " said Sheriff Shrum. " He's been trained and he came to us with 5 years of training prior to being part time at the Grundy County Sheriff's Office."
Deputy Holmes is back on duty, after being placed on a standard two-week leave.
"There's been a couple of debriefings and we've got to make sure we take care of our people as well as the community too because the community needs to grieve and it's been difficult for all of that to happen here because there's been so many rumors," said Sheriff Shrum.
The TBI continues its investigation into Comer's death. Those findings will be passed on to the District Attorney to take a look at the case.
"We're looking for some answers as well, " said Sheriff Shrum. " There's some things that we can't discuss, that we believe will come out as part of the investigation."
Jacky bean, the man Comer was riding with, is now facing charges including attempted first degree murder. Officials say Bean has an extensive criminal background including aggravated assault, drugs and weapons charges and he is well known to the department.
"My part-time deputy makes $10.50 an hour and he's out here trying to protect the community," said Sheriff Shrum. "We want them to be prepared for anything that they face and unfortunately we don't always get to pick the situation that we're in."
"We just have to react and it's tough sometimes," Sheriff Shrum added. "So we're dealing with that now in this agency."
The men are said to be part of the hit squad that ambushed Khashoggi in Turkey.
The Trump administration has sanctioned 17 Saudi officials for their alleged involvement in the killing of Washington Post columnist Jamal Khashoggi, the first economic penalties from the U.S. over the brutal murder that has spawned a diplomatic crisis.
The 17 individuals, the U.S. said, are the 15-man hit squad that traveled to Turkey to carry out the operation, the Saudi consul general in Istanbul, Turkey, where the killing took place, and a senior adviser to Crown Prince Mohammed bin Salman.
It's the same list of people that the Saudis themselves have blamed and arrested for the killing, which the Saudi government at first denied, then called an accident, before labeling it a rogue operation. The 17 were also among the 21 Saudi officials that the U.S. already revoked or banned U.S. visas for.
(Leah Millis/Pool via AP) Secretary of State Mike Pompeo shakes hands with the Saudi Crown Prince Mohammed bin Salman in Riyadh, Saudi Arabia, Oct. 16, 2018.
The Saudis have maintained that it was this small group of officials who are solely responsible for Khashoggi's murder, admitting Thursday that the killers drugged and killed the writer and critic of Crown Prince Mohammed bin Salman inside the consulate, before dismembering his body and handing it over for disposal by ...
The Saudi prosecutor said Thursday all 21 of them are in custody, and 11 of them had been indicted, with the prosecutor requesting the death penalty for five of the 11.
With the sanctions, the U.S. freezes all assets for the men and blocks any U.S. persons from doing business with them. While that's unlikely to make much of a difference with the group all imprisoned in Saudi Arabia, the sanctions do send a message that the U.S. takes the issue seriously.
That group includes the deputy intelligence chief Ahmed al-Asiri, who has been blamed by the Saudis for authorizing the operation. The Saudi prosecutor's spokesman and deputy attorney-general Sheikh Shalan al-Shalan said Thursday one unnamed individual was responsible, but did not name Asiri. Still, it's clear the Saud...
The central question now is whether the U.S. will be willing to go along with that or whether they will directly implicate the crown prince. Republican and Democratic members of Congress have said there are signs he gave the command, but so far the administration has refused to go that far.
"The United States continues to diligently work to ascertain all of the facts and will hold accountable each of those we find responsible in order to achieve justice for Khashoggi's fiancée, children, and the family he leaves behind," Treasury Secretary Steven Mnuchin said in a statement.
Secretary of State Mike Pompeo also said Thursday that his agency "will continue to seek all relevant facts, consult Congress, and work with other nations to hold accountable those involved in the killing of Jamal Khashoggi."
But National Security Adviser John Bolton said on Tuesday that recordings of the killings do not implicate Prince Mohammed, sometimes known by his initials MBS. "I have not listened to the tape myself, but in the assessment of those who have listened to it, it does not, in any way, link the crown prince to the killing,...
Saudi Foreign Minister Adel al-Jubeir said much the same Thursday, telling reporters during a press conference, "Absolutely, his royal highness the crown prince has nothing to do with this issue."
Mnuchin added a rare rebuke from the Trump administration for the Saudis' human rights record in his statement, too: "The Government of Saudi Arabia must take appropriate steps to end any targeting of political dissidents or journalists."
Google released its year-end Google Zeitgeist on Tuesday, which lays out the top-gaining search terms over the past year. The hugely popular social networking site "Myspace" showed the biggest gain in search queries, followed, somewhat worryingly, by the Greek god of war, "Ares." "Baidu" was next--both a Chinese search...
A slumping PC business affected Intel’s business during the third quarter, but the company believes brighter days are ahead with its new Core and Atom chips.
The company Tuesday reported no growth in revenue or profits during the quarter ending Sept. 28. The company reported a profit of $2.95 billion, compared with $2.97 billion in the same quarter last year. Intel reported earnings per share of $0.58.
Quarterly revenue came in at $13.48 billion, compared with $13.46 billion in last year’s third quarter. The consensus estimate from analysts polled by Thomson Reuters was for $13.46 billion.
Intel’s earnings came in as expected, and the company had “modest growth in a tough environment,” said Intel’s CEO Brian Krzanich, in a statement.
Looking forward, the company hopes for growth through new products, Krzanich said. The company announced fourth-generation Core processors code-named Haswell for PCs and tablets. It has also started shipping new Atom tablet processors code-named Bay Trail, which are expected to become available in devices starting this...
In addition, Intel is also chasing the wearable and embedded sector with the a new chip line called Quark, which consumes less power than Atom chips. The chip was announced at the Intel Developer Forum in September.
“Since August we have introduced more than 40 new products for market segments from the Internet-of-Things to data centers, with an increasing focus on ultra-mobile devices,” and hybrids, Krzanich said.
Revenue for the PC Client Group was $8.4 billion, down 3.5 percent year-over-year. Growth was primarily driven by Data Center Group, which deals in server equipment, with revenue of $2.9 billion, growing by 12.2 percent.
PC shipments during the third calendar quarter fell by 7.6 percent compared with the same quarter last year, according to IDC. Earlier, IDC had projected a 9.5 percent decline shipments during the quarter, but business purchases were stronger, driven by the looming support expiration for Windows XP, coming in April of ...
Intel is projecting revenue of $13.7 billion, plus or minus $500 million, for the fourth fiscal quarter of this year.
Lagos State Governor, Akinwunmi Ambode and the Vice Chancellor, University of Lagos, UNILAG, Prof. Oluwatoyin Ogundipe on Tuesday charged members of the society to show extra compassion to retirees because of their numerous contribution to societal development.
The due spoke at a two-day training for top civil servants in Ikeja, Lagos, Southwest Nigeria.
Speaking at the event, Ogundipe, called for support for retirees, saying that the training for retirees and those to be retired put up by the Lagos State Government was very important and timely.
He maintained that for any personnel not to prepare for life after retirement, connoted that such person would not have anything to fall upon, expressing optimism with the way government was planning for its workforce not to suffer after retirement, a feat considered okay and in order.
Today, I think Padilla might have been moved, as many of us were, by the powerful imagery of this historic moment and by the cadence of Blanco’s call to “gaze into the lucid blues of our shared horizon to breathe together, to heal together.” But Padilla, a man “aged by clarity,” might have warned Blanco about the peril...
And Padilla would also point to the fissures of an on-point strategy of engagement that is unfortunately accompanied by incongruent moves.
This moment of openness wouldn’t have been possible without the relentless pressure that Cuban dissidents have exerted on the Cuban government, risking their lives, taking beatings, serving jail time to expose violations of the most basic human rights.
Yet not a single dissident was invited to this ceremony, and the excuse that there was no space was contradicted by photos showing plenty of it.
The Cuban government made sure dissidents were nowhere near. Although people were allowed to gather outside the embassy, dissidents were kept away by Cuban police. Fourteen of the Ladies in White, who peacefully march after church on Sundays, were arrested, according to reports, to keep them from reaching the embassy.
Old Glory flies in Havana again — a magnificent symbol of freedom and democracy against a serene blue sea, yet enclosed by the tall bars of the reopened embassy, an island within an island. No longer the flag of the enemy, but of the “neighbor,” as Secretary of State John Kerry cast the new fragile relationship.
Yet the Cuban government considers its own citizens enemies (including Cuban-American journalists with insider knowledge and affinity for Padilla poetry). The reason: simply thinking differently and pushing for the same reforms Kerry mentioned in his speech.
Kerry’s was a memorable speech that hit fertile if calculated notes, including the mention of Cuban-American contributions — all the more extraordinary because it was broadcast on Cuban television, not in edited, censored format as is customary, but in full.
Those are words that, like the flag, are a beacon of hope amid a dictatorship that has lasted too long, all of the 56 years of my life.
He was a man of his time, and ours.
