Sun protection - why?

Clearly, nobody wants a hurting, itching sun fire. In addition, without visible sun fire sunbeams can damage. The sunlight consists among other things of UV radiation, which can be divided as follows:

Strahlung  Wellenlänge   verantwortlich für :
UV - A      320 - 400 nm    Skin cancer emergence trip of Mallorca acne (together with lipiden +                                        emulsifying agents) skin aging
UV - B      280 - 320 nm    Sun fire chronic light damage skin cancer

Contactors can one itself by cotton clothes and by sun protective agents with appropriate light protection factors

 

What at all is "light protection factor" called?

                                  Erythema swelling time with light protection
Light protection factor (LF) = Erythema swelling time without light protection

Erythema swelling time = time up to the sun fire

By LF the time is understood, in which one can expose oneself with sun protective agent longer to the sun than without.

The LF4 means thus that one can remain with sun protective agent the quadruple time in the sun as without.

Does one take now oil, gel, milk or an alcoholic solution?
Die riesige Auswahl ist kein Werbegag, sondern je nach Hauttyp/Bedingungen, ist ein bestimmtes Präparat geeignet

Preparat Advantage Disadvantage
alcoholic solutions They stick and do not grease not (applicably with strongly greasy skin) There is the danger of the skin drainage and skin irritation. They are fast rinsed out by sweat
Oil They are water resistant, possess a natural light protection and feel pleasantly on the skin. It only the LF 6 achievement that oil film obstructs the warmth and liquid exchange of the skin with the environment. By sweating the oil film can tear up; a light protection is ensured no more then
Hydraulic gels They are recommended, if a fat-damp hauttyp or an acne is present. They are for persons, who suffer from Mallorca acne, the only preparation without for the illness the responsible persons of lipide and emulsifying agents. Only disadvantage is the thin film, which stays on the skin
OW emulsions (milk/creams) They are well brushable, washable, pleasantly on strike and possess a cooling effect. They possess the highest effectiveness regarding the LF's They contain the trips for Mallorca acne
Water resistant preparing Water resistant preparing protect v.a. Water sportsmen, who longer time in the water are, before the UV radiation, which penetrates also up to Schnorchern. After swimming and drying the sun protective agent must again laid on

 

The most important rules for sun-hungry! 1/2

- Renewed laying on of sun protective agents does not extend the time, which can remain one according to LF in the sun.

- tanning lotion does not offer protection

- High sun protection factors do not obstruct the tanning lotion.

- Also in the shade and with covered sky one becomes brown.

- plastic fiber do not offer protection contrary to cottons clothes.

- in the winter sun protection is more important than in the summer, since the skin trocknerist pigment-poorer and. In addition it comes that the snow reflects the sunlight additionally and the solar radiation by cold weather not when is so strongly felt. Sun protective agents with high light protection factor and higher fat portion lips, nose and lids are recommendable must with Sunblockern (pastes or pins) be protected.

 

The most important rules for sun-hungry! 2/2

- Babies to direct sun exposure do not expose. They should be in the shade, be protected by clothes and put on a Sonnenhuetchen. In the face a baby cream with high light protection factor can be used.

- Certain medicines know sensitivity in relation to sun exposure (also Solarium! and sun fire and sun allergies increase release,; e.g.: Johanniskrautzubereitungen, Furosemid, Rivanol, Tetracycline, (e.g. Doxyicyclin), Ciprofloxacin etc.. At the best one one reads oneself in this connection the enclosing notes of the medicines, which one must take in this time.
- Also certain plants can release so-called photoallergische reactions: e.g. Wiesenbaerenklau (only by contact with this plant), sellerie, garden lozenge, Citrusfruechte and Bergamottoel (often contain perfume).
