most commonly also called liver spots,or solar lentigo
Generally associated with age and exposure to sun and/or sunbed use, these areas of pigmentation range from light to very dark brown and are common on hands and arms, face (and scalp if bald), neck, chest and shoulders. They usually increase in number and size after a person reaches about 40 years of age.
In spite of being benign and flat, many people consider them unsightly, especially as they are associated with aging. Prior to ACP treatment, it is advisable to have age spots seen by a doctor.
