Description
Types of Hyperpigmentation (excessive pigmentation, dark spots)
The best treatments involve inhibiting the production of the skin pigment melanin, encouraging the shedding of the older, outer pigmented layers of skin, and reducing the stimulus for melanin production by protecting the skin from the sun. Methods of treating pigmentation:
Inhibit the production of the skin pigment melanin

Lipodermatosclerosis
Tue, 27 Jul 2010 23:00:00 +0100 | Dermatologic Therapy
The most commonly recognized form of lipodermatosclerosis (LDS), chronic LDS presents with induration and hyperpigmentation of the skin involving the one or both of the lower legs in a characteristic "inverted champagne bottle" appearance. Associated with venous insufficiency, LDS is most common in middle aged women. In addition to chronic LDS, an acute form may also occur and is often misdiagnosed as cellulitis, inflammatory morphea, or erythema nodosum. The "acute" refers to the symptoms present that are exquisite pain. Treatment of LDS is based on the clinical presentation with compression therapy as the mainstay of treatment if tolerated. For acute LDS, patients often cannot tolerate compression therapy due to pain. We advise the use of fibrinolytic therapy, if available, until the pat...
Efficacy of a new fractional CO2 laser in the treatment of photodamage and acne scarring
Tue, 27 Jul 2010 23:00:00 +0100 | Dermatologic Therapy
This study evaluates the efficacy and safety of a novel fractional CO2 laser device for improving facial rhytids, hyperpigmentation, enlarged pores, skin laxity, and acne scarring. Subjects (n= 15) were treated three to five times at 3-week intervals. Biopsy specimens were used to evaluate healing response and neocollagenesis. Clinical improvement was rated on a quartile rating scale from digital photographs. Subject discomfort during treatment was evaluated on a scale of 0 to 5. Fourteen subjects who completed the study achieved good to excellent improvement in overall appearance, with 60% rated excellent. Improvement in photodamage was good to excellent in 92% of subjects, and reduction in rhytids was good to excellent in 85%. A total of 79% of subjects achieved good to excellent improve...
Comparative study of trichloroacetic acid versus glycolic acid chemical peels in the treatment of melasma
Thu, 22 Jul 2010 05:34:00 +0100 | Indian Journal of Dermatology, Venereology and Leprology
Conclusions: A prepeel program of daily application of 12% GA cream at night for 2 weeks, followed by graded increase in GA and TCA concentrations proved to be an equally effective treatment modality for epidermal and mixed melasma. There are hardly any major side effects, and regular use of sunscreens prevents chances of postpeel hyperpigmentation. GA peel is associated with fewer side effects than TCA and has the added advantage of facial rejuvenation. (Source: Indian Journal of Dermatology, Venereology and Leprology)

Partial unilateral lentiginosis associated with nevus of Ota
Thu, 15 Jul 2010 06:22:12 +0100 | Journal of the American Academy of Dermatology
To the Editor: A 25-year-old otherwise healthy female was referred to our department for the evaluation of pigmented facial lesions. Localized hyperpigmentation over the right eye had been present since birth. In the last 4 years, she noticed development of ipsilateral multiple brown lentigines extending onto the right forehead, temple, and eyelids, as well as a progressive blue-gray pigmentation on the right eyelid and tip of the nose.

Immuno-histochemical evaluation of solar lentigines: The association of KGF/KGFR and other factors with lesion development
Sun, 11 Jul 2010 23:00:00 +0100 | Journal of Dermatological Science
Conclusions: The upregulation of KGF/KGFR might induce the formation of rete ridges and hyperpigmentation. The reduced levels of all examined proteins (except TYR and K15) suggest a possible inactive status (dormancy or quiescence) of advanced lesions. (Source: Journal of Dermatological Science)
Treatment of Periorbital Wrinkles Using a 2,790-nm Yttrium Scandium Gallium Garnet Laser
Thu, 08 Jul 2010 23:00:00 +0100 | Dermatologic Surgery
Wrinkle formation usually accompanies skin aging. Periorbital wrinkles in particular are an early sign of skin aging. Therefore, several modalities have been developed to treat periorbital wrinkles, including topical applications, surgical techniques, and laser resurfacing. The 2,790-nm yttrium scandium gallium garnet (YSGG) laser has been increasing in popularity recently, but there have been no investigations into the use of a 2,790-nm YSGG laser for the treatment of periorbital wrinkles. To evaluate the clinical efficacy of a 2,790-nm YSGG laser for treating periorbital wrinkles. Ten Korean patients (Fitzpatrick skin type II[ndash]V) with periorbital wrinkles were enrolled in this study. They were treated two times with a 4-week interval using a 2,790-nm YSGG laser. The treatment parame...

Treatment of Facial Postinflammatory Hyperpigmentation with Facial Acne in Asian Patients Using a Q-Switched Neodymium-Doped Yttrium Aluminum Garnet Laser
Thu, 08 Jul 2010 23:00:00 +0100 | Dermatologic Surgery
Postinflammatory hyperpigmentation (PIH) due to facial acne commonly occurs in Fitzpatrick skin types IV to VI and can have a considerable effect on quality of life. The sequelae in terms of pigmentation are often the main reason for consulting a dermatologist and take precedence over the acne itself. The purpose of this study was to evaluate a new combined photoacoustic[ndash]photothermal low-fluence Q-switched neodymium-doped yttrium aluminum garnet (QSNY) laser in the treatment for facial acne and PIH. Twenty individuals underwent five weekly full-facial treatments using a QSNY laser at 1,064 nm. Another 20 individuals underwent five weekly facial acne treatments by extraction of comedones, and intralesional injections into severely inflamed papules were performed at each treatment sess...
