[:en]Some of the most common questions that individuals ask aesthetic doctors concern pigmented lesions. Pigmented lesions are very common, with most people having it on their skin. It can be in brown, black or blue in colour, or even mixed with black or brown lesions. Among the most common lesions are keratoses, moles, freckles, sun spots and melasma. Sun spots, also known as lentigines, are harmless, flat, brown discolorations of the skin which usually occur on the back of the hands, neck and face of people over the age of 40. These spots give away a person’s age and are caused by the skin being exposed to too much sun over the years without adequate sunscreen protection. Melasma is an unrelated condition also characterized by dark pigmented patches on the face, but is usually caused by hormonal fluctuations due to pregnancy or the use of oral contraceptives.
General skin lightening treatments have become possible today thanks to advances in
medical laser technology. Using non-invasive laser therapy, it is possible to effectively
treat skin surface pigmentation conditions such as melasma, sun spots, and uneven
dark patches due to the overproduction of melanin in the epidermis of the skin.
Laser treatment offers an effective means for the removal of pigmented lesions. The
treatment is quick and comfortable, and there is no need for any needles or anaesthesia.
The laser works by targeting the brown pigment, or “melanin,” present in the skin of
these spots. This pigment absorbs the laser’s energy and becomes scattered within the
skin’s tissues. The rest is done by the body’s own immune system as the skin’s cleansing
cells, called “macro-phages,”which digest the excess pigment and clear it from the area.
Usually sun spots would require a few treatments for removal, although larger and
darker spots may require more. Though some spots can be removed permanently, laser treatment can slow down the ageing effects of the skin.
