Since burns the surface up to skin cancer, excessive exposure to the sun can have effects of short-and long-term that are impossible to avoid.
UV-B RADIATION AND SCALDS
Rays UVB rays are the rays that cause scalds. The types of light skin is much more sensitive and react more to the UVB. As such, they should use a protection factor very high, with the FPS 50+, where they are exposed to the sun.
On the other hand, the types of skin darker are naturally more protected and can use a SPF 30 in solar moderate.
The protection factor of a sunscreen is related to the duration of protection: the higher the SPF, the longer the duration of protection.
An SPF 50 or higher provides protection equivalent to a SPF 30 but will have a duration of more than.

FOUR GOLDEN RULES TO PREVENT SCALDS
- Avoid exposure between noon and 4 pm. This is the period that the UV rays are the most dangerous.
- Keep children in the shade. For safety, children under 3 years of age should not be exposed to the sun under any circumstances.
- To use clothing. Must wear opaque whenever possible, as well as wide-brimmed hats and sunglasses with UV filter.
- Re-apply sunscreen every two hours even if it is water proof. Remember to apply sunscreen enough in the back, neck, ears and feet.
LOCK THE PREMATURE AGING – UVA
There are levels of protection differ between UVA and UVB rays. The protection on UVA is known as the PPD (Persistent Pigment Darkening).
Solar protection with a PPD that high provides a better protection against damage caused by UVA rays, responsible for:
- allergies to the sun;
- premature aging of the skin;
- the emergence of brands of pigmentation;
- a higher risk of cancer.
A sunscreen with a SPF/PPD offers the best protection against UV rays (or, in other words, more security in the sun exposure to prevent scalds).
TO PREVENT SCALDS – SUN PROTECTION
Choose the sunscreen right can be a dilemma. With all the different names and abbreviations (FPS, PPD), it is not always easy to find what you need.
To avoid scalds and burns, need to choose the SPF (sun Protection Factor) correct. Is indicated in all the sunscreens and there are four levels of protection:
- Reduced (factor 6 to 10);
- Medium (15 to 25);
- High (30 to 50);
- Very high (50+).
Depending on your phototype, your skin reacts more or less quickly in the sun.
Although some skins are brown naturally, some are more fragile or in need of a protection factor high constantly. With a protection factor high, your skin is more protected.
The phototype classifies people according to how your skin reacts to the sun. There are 6 types:
- Phototype I: skin milky, burns always, never tans, many freckles.
- Phototype II: fair skin, burns always, sometimes tans lightly, many freckles.
- Phototype III: light skin to dark, burns sometimes, tans always (tan medium), some freckles.
- Phototype IV: dark skin, never burns, tans always (tan dark), without freckles.
- Phototype V: brown skin, never burns, tans always (tan dark), without freckles.
- Phototype VI: black skin, never burns, no freckles.
