Age spots are areas of hyperpigmentation that appear on skin damaged by the sun's ultraviolet rays. They are also called liver spots, though they have nothing to do with the liver, or solar lentigines. Age spots are benign, but many individuals find them unattractive and want to be rid of them. They are found on parts of the body exposed to the sun, such as the backs of the hands and the tops of the feet, as well as the face, back, shoulders, and arms. They can be freckle-sized or unsightly blotches.
Some individuals have only a few age spots while others have many clusters of them. They are not necessarily a consequence of aging, though most develop after individuals turn forty years old. However, they are also seen on younger individuals. Thankfully, there are ways to treat age spots effectively.
In cryotherapy, the doctor uses liquid nitrogen to destroy the extra pigment in the age spot. They simply dip a cotton swab in the liquid nitrogen, which is -320.44 degrees Fahrenheit, and apply it to the affected area. Though it is a simple procedure, the patient still needs to prepare for it and have a consultation with their doctor. Some patients have adverse reactions to such extreme cold, and they might be taking blood-thinning medications they will need to stop, at least temporarily, before their treatment. Some dermatologists also recommend for patients to take an antibiotic or painkiller before their treatment.
