With the title “Skin Care” initiated a series of articles that we want to help prevent irreversible damage to our skin.
“The skin has memory” is not a topic to scare us, we must learn to enjoy the sun without being skin. Sunburn is the main risk of skin cancer, but small amounts of ultraviolet radiation are beneficial to health and desempañan an essential role in the production of vitamin D.
Excess ultraviolet radiation causes mutations in cellular DNA and genetic alterations induced skin tumor formation, oxidative stress cause produces free radicals and related accelerated skin and reduce the aging immune system effectiveness.

But if adults is dangerous excess solar radiation, children are particularly sensitive. Two thirds of solar exposure of his life receive in childhood. A sunburn in childhood doubles the risk of developing melanoma later in life.


Skin types are classified into phenotypes, there are six according to their characteristics are:

  1. Phototype I: very white skin, freckles and red hair. Is always burning. It is never tans.
  2. Phototype II: fair skin, blond hair and blue eyes. It burns very easily. Minimum tan.
  3. Phototype III: slightly brown skin. It burns easily. Gradual tan.
  4. Phototype IV: dark skin. Occasionally it burns. Quick tan.
  5. Phototype V: very dark skin. Rarely burns. Tanning intense and fast.
  6. Phototype VI: black leather. It is never burned. Maximum tan.

Two patterns of sun exposure risk are considered:

  • Acute intermittent (sunbathing on the beach and outdoor sports) exposure is associated with an increased risk of developing melanoma and basal cell carcinomas.
  • Chronic sun exposure and cumulative (professions outdoor) is associated with an increased risk of developing squamous cell carcinoma and actinic keratosis.

The groups considered at risk and, therefore, should have a greater prevention:
