Mongolian spots are congenital hyperpigmented areas of varying size and shape and are usually confluent grayish-blue in color. They are found most frequently in the sacral region and typically disappear during childhood. Occasionally, they persist to adulthood.

The use of Q-switched alexandrite laser treatments for Mongolian spots and examinaton of the therapeutic outcomes of 26 Japanese patients with Mongolian spots was reported in the Dermatologic Surgery, Volume 34, Number 12, December 2008 , pp. 1689-1694(6).


A good therapeutic outcome was achieved overall, but some adult female patients subsequently developed severe postinflammatory hyperpigmentation. Sacral Mongolian spots were more laser-resistant than extrasacral Mongolian spots.


The outcome correlated with the age of patients at the initiation of treatment; therefore, sacral and extrasacral Mongolian spots should be treated before 20 years of age. To avoid severe postinflammatory hyperpigmentation, the optimal interval between laser treatments and the use of other treatment modalities including Q-switched ruby laser, Q-switched neodymium-doped yttrium aluminium garnet (Nd:YAG) laser, or bleaching creams should be considered.

  • Fractional photothermolysis, based on creating spatially precise microscopic thermal wounds, is performed using a 1550-nm erbium fiber laser that targets water-containing tissue to effect the photocoagulation of narrow, sharply defined columns of skin known as microscopic thermal zones.

    Fraxel resurfacing has been shown to be both safe and effective for facial and nonfacial photodamage, atrophic acne scars, hypopigmented scars, and dyspigmentation. Because only a fraction of the skin is treated during a single session, a series (typically 3 to 6 treatments) of fractional resurfacing at 2- to 4-week intervals is required for the best clinical improvement.

    Many physicians have reported that a series of Fraxel treatments can achieve a similar clinical result for atrophic scars compared with traditional ablative laser skin resurfacing with either CO2 or Er:YAG 2940-nm lasers. However, the improvement seen after a series of Fraxel treatments for perioral laxity and rhytides often falls short of the impressive results that can be achieved with ablative laser skin resurfacing.

    Fifty years from now people won’t ask each other if they’ve had aesthetic surgery; instead, they’ll ask why they didn’t! That’s according to Dr. Ziya Saylan, Istanbul, Turkey.

  • Laser-induced postinflammatory hyperpigmentation could be a limiting factor for selecting patients appropriate for the use of ruby laser in the treatment of lentigenes, especially in dark-skinned individuals.

    A controlled comparison study in a university-based laser clinic center was conducted recently and published in Dermatologic Surgery, Volume 34, Number 11, November 2008 , pp. 1465-1468(4). Ninety-one solar lentigines in patients with skin type II, III, and IV were enrolled. All patients were followed for 6 months for frequency of side effects. Before-and-after photographs and images from all follow-up sessions were taken and then assessed by a blinded dermatologist for the evaluation of side effects.


    Complete clearance was achieved in all patients. Postinflammatory dyspigmentation occurred in 7.8% patients with Fitzpatrick skin type II, 9.8% patients with type III, and 16.6 patients with type IV (p=.67); all improved over a 6-month follow-up period.


    Q-switched ruby laser treatment is a safe procedure for the treatment of solar lentigines even in dark-skinned individuals. Considering routine factors in addition to melanin content alone is required for minimizing side effects, especially postinflammatory hyperpigmentation in darker skin.
