Dark Patches prevention
With the arrival of summer it is important to consider the effects of ultraviolet radiation on the skin.
Just 15 minutes´ exposure to the sun can trigger the release of free radicals that cause oxidative damage to cell membranes and nuclear DNA. Initially these changes are subclinical, which means they are not visible to the eye. However, with repeated exposure the damage is cumulative and over the years can lead to the appearance of precancerous lesions such as actinic keratoses and malignant lesions such as basal cell carcinoma and squamous cell carcinoma.
Malignant melanomas may appear directly, or from a nevus (freckle) that changes into a melanoma. It is recommended an annual or every 6 months medical examination in case of having a family history with melanoma, many nevi, a new nevus or changes in an existing one.
These lesions clinically manifest themselves in the skin as red scaly patches, indurated plaques or ulcerations of the skin.
Over time these precancerous lesions, called actinic keratoses may develop into malignant tumors (squamous cell carcinoma).
Photodynamic therapy is a new treatment that can selectively treat these lesions.
- Treats and prevents actinic keratosis or precancerous lesions.
- Activates the natural processes for photorejuvenation and photoprotection of the skin.
- It favors the mechanisms of repair improving the appearance of the scars ..
- Therapy for the treatment of acneé since it will eradicate P. Acnes, the bacteria responsible for acne and also has an anti-inflammatory effect on inflamed lesions.
Non-melanoma skin cancer is the most prevalent cancer. It is more common in people with clear phototype that have been exposed to ultraviolet radiation or who have suffered from burns. Malignant melanoma is the most dangerous type of skin cancer. Dermatological controls of lesions are necessary to treat skin cancer in time.Curriculum
