Sunburn, as the name suggests, is a burn of the skin caused by overexposure to ultraviolet radiation in sun rays. This exposure may come in the form of perceived UV radiation or in the form of infrared radiation. This exposure can must be avoided at all costs or would you be wise to simply avoid the sun altogether? As with botox treatment.
Though it is not possible to escape ultraviolet radiation, there are measures that can be taken to lessen the chances of someone getting sunburned. Then again, simply staying indoors or wearing protective clothing isn’t enough to protect one from the damaging effects of UV radiation.
This is where SPF comes in. So,
what is SPF and how does it affect the skin?
SPF stands for Sun Protection Factor and it is a measure of how well a person’s skin can protect him or her from UV radiation. It is used to measure how long a person can remain in the sun, relative to the amount of time that a person can be exposed to the sun if no protection were used.
A sunscreen with a SPF of 10 allows a person to last ten times longer under the sun than a sunscreen with a SPF of 50. So, for example, a sunscreen with a SPF of 10, allows a person to last ten times under the sun than a sunscreen with a SPF of 50.
SPF gets much higher when the sun is more directly exposed. So, for example, if you go to the beach and plan to swim for a long period of time, you should choose a water-resistant sunscreen with a SPF of at least 40.
Another thing that you should look for in sunscreen is the inclusion of UVA and UVB protection. Since UVA radiation is known to cause cancer, it is included in the dictionary of cancer as “that type of radiation had by cation across a surface sooner than in its transition from radiation to electuration.”
Thus, a sunscreen that protects against both UVA and UVB radiation is immuno-suppressive. It means that it encourages more melanin production in the skin. This may be helpful with lighter skins but, for darker skin, it may lead to a Vitamin D deficiency.
For this reason, you may want to look for the phrases “water-resistant” and “sweat-resistant”. The first allows for up to 40 minutes of exposure, after which the protection takes a bit of ten minutes to start wearing off. The second, however, allows for twice the protection and it also allows the sweat to act as a barrier of protection.
Pose offers an invisible sunscreen that is 100% oil-free and packages it in a waterproof tube. It can be used to protect the skin and eyes from the sun. It is lightweight and has a great refreshing feel.
Dieric Acid is another great product for those who are having problems with rosacea and who are sensitive to sun exposure. It is a product that has actually been used by Cleopatra. It is usually in the form of a cream that can be applied to the face and then massaged around. It then provides a cooling sensation and acts as a barrier between the skin and the sun.
You can also use sunscreen with micronized zinc oxide, which is great because it has tiny particles that penetrate the skin and doesn’t leave a greasy feel. It is also known to be effective in helping to clear up acne. There are also sunscreens that contain oxybenzone and/or titanium dioxide, which has been proven to provide a safe and effective layer of sun protection.

A word of caution, though: many of these ingredients have not been properly evaluated for safety, and could, therefore, actually be causing you harm.
Though many of the ingredients listed do not provide any protection from the sun, choosing the right sunscreen can single-handedly save you from the risk of skin cancer. Look for those with a high SPF and those that contain zinc oxide, which is known to be safe and effective in keeping the sun’s harmful rays at bay.
