One of the things that many people experience, after many years of over exposure to the sun, is sun spots, which are also known as actinic keratoses. The characteristics of sunspots include dry reddish brown bumps on the skin, as well an uneven skin color. Sun spots are caused by the excessive exposure to UV light, which occurs with overexposure to the sun. This results in an increased production of melanin, which is the pigment in the upper layer of the skin. The discolorations associated with sunspots are a result of uneven skin color production.
Typically, sunspots are found of the neck, shoulders, arms, face or the back of the hands. In addition to being not attractive from a cosmetic perspective, sunspots are also known to be pre-cancerous lesions and require proper sun spots skin treatment or removal by a highly qualified and experienced dermatologist.

Treatment of sunspots varies from patient to patient, as well as the area and extent of the sun spots. In some cases an application of freezing liquid nitrogen is sufficient or the application of a prescription cream. In other cases a chemical peel will be required or treatment using photodynamic laser therapy.
The goal of the treatment is to eliminate or fade the sunspots cosmetically, as well as to prevent these lesions from developing into skin cancer in the future. In addition, the dermatologist and their staff will work with the patient to educate them in the proper ways to prevent these pre-cancerous lesions from developing in the first place!
