Needleless transcutaneous pneumatic injections (TPIs) are a minimally invasive way to deliver the solution into the skin for therapeutic purposes. The suggested action mechanisms of TPI therapy include mechanical stimulation, immediate tissue shrinkage and late wound healing.Thirteen Korean patients were treated with TPI for atrophic skin disorders, including acne scars, striae albae, post-furuncle, or carbuncle scars, and horizontal wrinkles with lipoatrophy. At each TPI treatment session, a single pass was made along with the atrophic skin lesions without overlapping. Thereafter, two dermatologists objectively evaluated the clinical improvement in the lesions in the photographs via the global aesthetic improvement scale (GAIS).One month after the final treatment, the overall mean GAIS score was 2.3 ± 0.8. Six of the 13 (46.2%) patients exhibited clinical improvement of grade 3, five (38.5%) patients grade 2 and two (15.4%) patients grade 1. The overall mean subjective satisfaction score with the TPI treatment was 2.3 ± 0.9. Six of the 13 (46.2%) patients achieved subjective satisfaction of grade 3, six (46.2%) patients grade 2 and one (7.7%) patient grade 0.The present study demonstrated that the TPI treatment is effective and safe for treating atrophic skin disorders of varying causes in Korean patients.

Pinhole method has been used to treat various types of scars and dermal tumors by making multiple small holes in target tissues of the deep dermis using an ablative 10,600-nm carbon dioxide (CO2) laser.We prospectively investigated the efficacy and safety of using a CO2 laser to treat periorbital syringomas via the pinhole method.A total of 29 patients with periorbital syringomas were treated with two sessions of CO2 laser treatment using the pinhole method at two-month intervals. Laser fluences were delivered under the following settings: pulse duration of 200 μs, frequency of 50 Hz, on time of 0.04, and an off time of 0.01.Among the 29 patients, 13 patients (44.8%) presented with small discrete papular syringomas, 10 (34.5%) had plaque-type lesions, and six (20.7%) had mixed lesions. Evaluation of the clinical results at 2 months after the second treatment session revealed marked clinical improvement (51-75%) in 10 of the 29 patients (34.5%), moderate clinical improvement (26-50%) in eight (27.6%), near-total improvement (≥ 75%) in seven (24.1%), and minimal improvement (0-25%) in four patients (13.8%).Our observations indicated that application of the pinhole method using a CO2 laser exerts positive therapeutic effects in Asian patients with periorbital syringomas.

Erythematotelangiectatic rosacea presents as persistent erythema and telangiectasia with frequent flushing and blushing on the facial and extrafacial skin. Additionally, papulopustular rosacea shows acneiform papules, pustules, and nodules with persistent plaque-form edema. Despite garnering only grade-C or -D level recommendations, a 585-nm or 595-nm flashlamp-pumped pulsed-dye laser can be considered as an effective therapeutic modality for the treatment of rosacea in patients who are refractory to topical and/or systemic treatments. In this report, treatment with a Q-switched 595-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser with low non-purpuragenic fluence proved to be safe and effective in treating early-stage erythematotelangiectatic rosacea in two female Korean patients. Laser treatment for rosacea was delivered with the settings of pulse energy of 0.4-0.5 J/cm(2), pulse duration of 5-10 ns, 5-mm spot size, 5 Hz, and 500 shots. Additionally, we found that remarkable therapeutic effects were achieved for both rosacea and melasma by combining Q-switched quick pulse-to-pulse 1,064-nm Nd:YAG and Q-switched 595-nm Nd:YAG laser treatments, which required only the changing of handpieces equipped with solid dye. In conclusion, we suggest that treatment with a Q-switched 595-nm Nd:YAG laser with low fluence may provide an additional therapeutic option for treating early-stage erythematotelangiectatic rosacea.

Laser treatments using 532-/1064-nm Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) lasers are popular non-ablative and selective photothermolysis therapies for pigmentary disorders. We treated three male Korean patients (aged 23, 27 and 24 years) for smoker's gingival hyperpigmentation using a 532-nm Q-switched Nd:YAG laser. At each treatment session, the laser was delivered at 1.2 J/cm(2) with a 5-mm spot size and appropriate overlap. Clinical improvement as well as complete healing of the treated gingiva was noted within 2 weeks after each treatment. We also observed that the therapeutic effects lasted more than 6 months.
