Preventing sunburn

Preventing sunburn
Prevention is the most effective therapy for sunburn. Effective individual and community educational programs can reduce sun exposure and increased use of creams or protective clothing. Avoid sun exposure during the maximum 10-hour solar radiation. oo-16. oo day.
It indicates the use of sunscreens with SPF-creams suitable for your skin type. SPF is the amount of ultraviolet energy required to produce erythema on protected skin to the amount of ultraviolet energy required to produce erythema on unprotected skin. Apply for at least 30 minutes before sun exposure and reapply every 2-3 hours or after swimming, sweating or shower. Apply before exposure of small children. It will use water-resistant SPF creams. will apply the cream at least 2 mg/cm2 to reach the SPF. Most people apply a concime of that amount.
Physical barriers (zinc oxide, titanium diozid) allow excellent protection against UV-A and UV-B and are photostat. Chemical barriers are used in most solar screenings. Paraaminobenzenic acid and esters are not indicated due to high rates of contact dermatitis associated. Other UVB blockers include salicylates and cinamates. Avobenzona contain UVA blockers, and terefitalidena drometizole trisiloxane.

Preventing sunburn
Wearing protective clothing, including hats and sunglasses ocgelari. Clothing can be treated to increase the product's SPF. Dark clothes, dried offers the highest protection. When the fiber is wet, water occupies the space between fibers and allows entry ultraviolet. Nylon clothing offers the lowest protection. Synthetic fabrics, Raiatea offers more protection from cotton. People are encouraged to use self-tanning lotions and creams that do not increase the risk of skin cancer or wrinkles. They offer sun protection. Avoid tanning salons. Avoid phototoxic administration of drugs or toxic agents that can interact with sunlight to avoid burning.
Pharmacological aspects of prevention include screening chemical and solar physics. No sunscreen does not confer 100% protection. There is no known effective oral sunscreen. Antimalarial drugs, vitamins A, E, beta carotene and oral paraaminobenzenic acid does not provide adequate sun protection. Systemic administration of vitamin C and E combined-SPF provides a minimum protection. 4. Solar screens are designed to protect the skin and not to prolong sun exposure. Although they can prevent burns, and immunosuppression caused by ultraviolet carcinogenicity is not avoided. It is better to use creams that block SPF 15 or 93% of UVB rays with SPF 30 to 97% blocking.
Prognosis sunburn
Preventing sunburn   Sunburn uncomplicated resolve spontaneously within 4-7 days without sequelae acute desquamation. Sunburn can exacerbate chronic diseases: chronic actinic dermatitis, herpes simplex, lupus erythematosus, eczema. May be associated with other diseases caused by heat, including stroke and dehydration. Long term exposure leads to premature formation of wrinkles, fotoimbatrinire, development of premalignant lesions, solar keratoses, development of malignancies: basal cell carcinoma, squamous cell carcinoma and malignant melanoma.
