Hyperpigmentation occurs when there is an increase in pigment (usually melanin) in a specific area of the skin. It can be caused by sun exposure, certain medications, inflammation, and hormonal changes.
Common hyperpigmentation conditions
Melasma usually appears on the forehead, nose and cheeks and is more common among women. This condition is often called "the mask of pregnancy" as it is associated with hormonal fluctuations, but it can also result from sun exposure and certain medications. Melasma is categorized according to where most of the pigment has accumulated – epidermal (upper skin layers), dermal (deep layers), or compound (both). This type of pigmentation can be difficult to eradicate, as it tends to recur.
Solar lentigo
–age or liver spots – are flat spots with clearly defined edges, tan or dark brown in color. These spots usually appear on areas of the body most often exposed to the sun (face, back of hands) and are caused by an excess of melanin in skin cells.
Poikiloderma of civatte is aging of the skin in the chest/cleavage area and on the sides of the neck. This condition is characterized by dilated capillaries, absent or excess pigmentation, and atrophy of the skin (due to decrease in collagen fibers and dermis layer elasticity). The condition results from prolonged exposure to sunlight.
Pigmentation conditions often require a combination of therapies.
Innovative laser therapy
Based on the application of high energy laser beams at a wavelength absorbed by melanin, this therapy can lighten or remove skin pigmentations. Results depend on the depth of the melanin and the color of the spot. Efficient treatment of pigmentation conditions involves combining a number of laser types (such as short wavelengths) or light technologies (such as intense pulsed light (IPL)). The therapy removes the surface pigment and creates a uniform skin tone. Furthermore, heating the deep dermal layers stimulates growth of fresh, healthy skin. This type of therapy can be used on the face, neck, back of the hands and on the upper chest.
The Integrated Center for Aesthetic Dermatology and Laser Treatments – Dermatology Division is equipped with the most advanced laser and light technologies, so that we can ensure our patients the best results using the lowest number of treatments. Treatments are effective for patients of all ages, however, treating dark skin requires added caution to prevent the appearance of light or dark spots following therapy.
An important note:
The recommended approach for treatment of pigmentation conditions combines different types of laser and light to achieve optimal results, with subsequent maintenance therapy. Results can be maintained by avoiding sun exposure and undergoing an IPL treatment once every six months.
A pigmented mole or lesion with uneven edges requires dermoscopic examination, and in some cases a biopsy to rule out malignancy. The ICADLT works in collaboration with the hospital's clinic for early detection of skin cancer.
