What is tan?
It represents the first reaction of the body defense against UV rays. The skin produces more pigment, which absorbs solar radiation, representing a barrier to their deeper penetration.
Tanning your skin involves two separate processes: immediate pigmentation and delayed pigmentation. Immediate pigmentation is caused by UVA radiation and consists of photo-oxidation of preformed melanin. Delayed pigmentation occurs 72 hours after exposure to UVA or UVB radiation and is associated with the production of new melanin.
The sun emits three types of ultraviolet rays:
* UVA (wave-length than) - responsible for tanning immediate and have carcinogenic potential in case of chronic exposure;
* UVB (medium wave length) - partially filtered by the ozone layer, producing late tan (sustainable), causing burns and prolonged exposure to unprotected and involve skin cancer;
* UVC (short wave length) - for the most part, are filtered by the ozone layer.
What is tanning?
The solarium is a device that emits a "conglomerate" concentrated UVA and in smaller amounts UVB. After a certain number of sessions, depending on skin color and how quickly react to ultraviolet rays, your skin will get the desired shade of tan.
The fact that exposure is a relatively controlled and it is not without risk, especially as impatience often cause those who wish to exaggerate the tan during the sessions. Side effects may include:
* Itchy irritation;
* Dehydration of the skin;
* Eye Injuries, if not using special goggles;
* Skin cancer - those whose first visit to a solarium occurred in adolescence or who have frequent or long sessions, shows a 70% higher risk of developing malignant melanoma.
What are the contraindications to use the solarium?
- History of skin cancer;
- People with very white skin, not tan, but only red in the sun;
- People with many pigmented nevi (moles) - have an increased risk of developing skin cancers;
- Allergy to the sun;
- Diseases that are aggravated by exposure to the sun (lupus erythematosus, cardiovascular disease);
- Treatment with drugs photosensitising (NSAIDs - ibuprofen, some anti-hypertensive, some oral and some antifungal agents) - increases the risk of burns;
- Pregnancy - is not an absolute contraindication, but permission is strictly necessary.
