Solar lentigines are common dark spots on the face, hands and arms, which are also known as “liver spots” (they have nothing to do with the liver). They can develop into seborrhoeic keratoses.
Melasma is a common patchy discolouration that usually appears on the forehead, cheeks and chin in those aged 25-50. Melasma can be distressing for patients and is often inherited as a genetic trait. Other causes can include sun exposure, birth control pills, medications, pregnancy or heat. It is important to wear sunscreen and minimize sun exposure to avoid worsening the condition. Treatments range from topical medications to laser treatments. There are many medical grade skin care products for the treatment of melasma, which stop or slow the melanogenisis process.
