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 is a shorthand for Sun Protection Factor and it is an indicator of how well one’s skin protects the person against UV radiation. It’s used to gauge how long an individual can remain in the sun in relation to the time a person could be exposed to UV radiation without protection.
A sunscreen that has SPF 10 allows the wearer to stay 10 times longer in the sun than sunscreen that has an SPF of 50. Thus, for instance, sunscreen with an SPF of 10 lets a person last 10 times more than sunscreens that has an SPF of 50.
SPF is much greater as the sun gets direct exposed. This is why, for instance when you visit the beach and intend to swim for an extended duration it is recommended to select a sunscreen that is water resistant with an SPF of 40.
Another aspect to be looking to in sunscreens is presence that provides UVA or UVB protection. Because UVA radiation has been proven as a cause of cancer it’s listed in the definition for cancer. It is defined as “that kind of radiation is caused the effect of cation on an area earlier than the transition from radiation to electurization.”
So, a sunscreen which shields against the effects of both UVA as well as UVB radiation can be considered to be immunosuppressive. This means it stimulates melanin production to increase in the skin. This can be beneficial for mild skin tone, however, for darker skintypes, it can lead to Vitamin D insufficiency.
This is why it is advisable to search for the terms “water-resistant” and “sweat-resistant”. The first is able to provide as long as 40 minutes exposure following which the protection will take about 10 minutes before it starts to wear off. The second offers two times the protection. It will also allow sweat to serve as a barrier to protection.
Pose provides an invisble sunscreen which is oil-free, and is packaged inside a waterproof tube. It is able to shield the eyes and skin from sun. It is light and offers an amazing, refreshing sensation.
Dieric Acid is another great product for people who are experiencing rosacea-related issues and people who are sensitive to sunlight. Dieric Acid is a remedy which was employed by Cleopatra. It usually comes made into a lotion that could put on the skin, and then massaged into the skin. It provides an icy sensation and functions like a shield between face and sun.
You can also apply sunscreen that contains micronized zinc oxide. It is very effective because it has small particles which penetrate skin, and don’t leave an oily feeling. It’s also believed to work to reduce acne. There are sunscreens that contain oxybenzone or titanium dioxide. It have been proved to be an effective and safe sunscreen.

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.
