What are the benefits of sunscreen?
Sunscreen has been in use for a long time. However, whether the use of sunscreen is right or wrong has been a controversial topic. Some experts believe that it has beneficial use while others feel that it is harmful to our health.
There are ample reasons brought up as to why one should use or not use sunscreen. You will find some of these reasons below.
Some of the experts attribute many good things to the use of sunscreen.
These reasons include:
1. Sunscreens have been approved in U.S by FDA since 1978. Basically, in the US, Food and Drug Administration body regulates sunscreens. Other countries as well have regulatory agencies that ensure that products released to the public do harm the users.
2. Sunscreen is hailed since childhood to prevent terrible sunburns and prevention of cancer.
3. The ozone layer has continually been depleting thus there is the need to shield the body from the
harmful UVA and UVB rays.
4. Sunscreens are also believed to prevent skin discolorations and the red-brown facial spots.
5. Additionally, they are known to slow down premature aging (development of wrinkles).
There are toxic worries attributed to the use of sunscreens. Majorly, sunscreens contain ingredients such as oxybenzone and retinyl palmitate which are of primary concern to most experts.
However, the use of these components and their effects on human health is not straightforward as you think.Many arguments arise on whether these ingredients are dangerous or not.
According to research, no data that shows that oxybenzone causes hormonal imbalances in humans. As well, no data has been brought up to demonstrate that it causes significant health issues.
Retinyl palmitate, on the other hand, is commonly known for its ability to prevent the skin from premature aging.
Similarly, no research has been able to prove that it increases the skin cancer risk to humans. In fact, it is a form of vitamin A naturally found in the skin.
As we know, retinoids, a form of vitamin A, has been used for a long time to prevent cancer in people with high risks of contracting skin cancer.
Though oxybenzone and retinyl palmitate have been hailed to be pretty low risk, many advocates that it is wise to avoid sunscreens with these ingredients.
It is true that sunscreens form part of most people’s lives. Some have used them since they were kids and have continually found them helpful. Some are useful while others are dangerous.
Finding a sunscreen without any adverse impact on you is wise. In case you have to use them, approved sunscreens are the best to use.
Sunscreen SPF Meaning
SPF stands for "Sun Protection Factor". When you use a sun screen that has a SPF 15, it means that you can stay in the sun 15 times longer before sunburn occurs than you will be able without protection.
By using sun block lotion you will be protected from the sun, and still be able to get a tan. Some are labelled as being water-resistant. These type stay on the skin longer, even if they get wet from pool water, ocean water, or sweat.
But water-resistant doesn't mean waterproof. Water-resistant ones still need to be reapplied, so check the label for reapplication times.
If you use sunscreen and want to be well protected from UV radiation consider the following sun protection information when choosing sunblock lotions.
1. Buy one that has a broad spectrum protection, blocks or filters out UV rays.
2. Always remember that the sun's rays are stronger with altitude, so you will need to use sunscreen with higher sun protection factor.
3. People with fair or sensitive skin should use one with a higher SPF, than those with darker skin.
4. It is a plus to use sun protection that contains not only a high SPF, but with added antioxidant vitamins like vitamin A, vitamin C and vitamin E to help fight free radicals. Try La Roche Posay Anthelios Antioxidant Sunscreen with broad spectrum protection & SPF 60.
5. Avoid the sun or seek shade from 10 a.m. to 4 p.m. when the sun's rays are strongest.
6. Apply an SPF 15 or higher protection.
7. Allow 30 minutes for skin to absorb it before going outside.
8. Wear a wide-brimmed sun protection hat.
6. Protect eyes with sunglasses that have a UV/UVB protection of at least 99%.
Check with your doctor to find out if you’re taking medications, that
will make you more sensitive to the sun to avoid sunscreen allergies.
10. If you want to protect the lips and avoid lip wrinkles use sunblock for lips.
11. Infant sun protection is very important as their skin is more sensitive to sunlight.
Find below the importance of melanin when sunbathing.
The effectiveness of sunblock is reduced if it's applied incorrectly or if it's washed off, rubbed off, or sweated off.
To make sure you're getting the maximum protection, apply an even layer, and reapply according to the directions.
Sunblock usually needs about 15-30 minutes to soak into the skin before you go outside.
Read the label to see how long you should wait.
If the label doesn't indicate how long, wait 30 minutes to be safe.
Melanin is a dark skin pigment, a natural substance that gives color to the skin, hair and the iris of the eyes. It is what makes our skin go brown when we are out in the sun; is what is called a tan.
What Produces this Skin Pigment?
It is produced by specialized skin cells called melanocytes. Everybody has the same quantity of melanocytes, and the amount of this skin pigment produced determines our skin color.
People with darker skin produce more quantity, that is why black and dark skinned people are better protected from ultraviolet light as well as premature skin aging.
Fair skinned people are less protected, and are more susceptible to skin cancer. The lack of these skin pigments causes albinism.
There are two types:
Eumelanin - is more abundant and darker.
Pheomelanin - red or yellowish color. More abundant in red or blondes.
Its production is dictated by our genes. Research shows that supplements containing this pigment simply don't work, so don't waste your money on those pills.
Whether from a day on the beach or hours spent in a tanning salon, the "tan" color your skin gets after baking under UV rays, is a sign of skin damage.
When it's exposed to UV rays our skin produces this dark pigment to protect skin cells from damage. When our skin is exposed to UV rays it produces more quantity, and may become darker over the next few days.
Everyone, no matter their skin tone, is at risk of skin damage. Your best bet for a safe tan is self-tanning. Below you will find self-tanning tips if you want to avoid UV rays.
With these self tanning tips you are going to get a perfect tan without damaging the skin.
A sunless tan is your best alternative if you are after a sun-kissed looking skin but want to avoid the harmful effects produced by ultraviolet radiation to the skin.
There are many choices of sunless tan lotions in the market. The latest will hydrate the skin and the clothes will be free of stains while giving you a perfect tan, how great is that?
They are made of a chemical called dihydroxyacetone (DHA) that colors the skin when in contact with the skin's proteins, giving it a darker appearance similar to a tan.
It only reaches the skin's top layer so will last just for few days.
You should know that while the FDA allows DHA to be "externally applied" for skin coloring, there are restrictions on its use.
DHA should not be inhaled, ingested, or used in such a way that the eyes and eye area are exposed to it because the risks, if any, are unknown.
Did you know...?
Sunless tan lotions won't stop your skin from getting the harmful UV rays when out in the sun, so you will still need to use sunscreen. Some may have, but check the label, and if is not sunblock in it, apply one with SPF 15 or higher.
Self tanners come in different forms:

You may have seen ads that promise to give you a golden glow just by swallowing a pill. Is this sound too good to be true, is because it is. These, so-called, tanning pills are unsafe, and none are approved by the FDA.
Some pills contain the color additive canthaxanthin. When large amounts of canthaxanthin are ingested, this substance can turn the skin to a range of colors, from orange to brown.
They can also cause serious health problems including:
