61. Characteristics and management of Asian skin. (PubMed)

, ranging from type III to IV Fitzpatrick's classification in Chinese and Japanese to type IV and V in Indian and Pakistani people. Asian skin tends to present postinflammatory hyperpigmentation, melasma, lentigines and freckles, nevus of Ota, and Hori nevus. The main skin diseases reported in Asians are acne, atopic dermatitis, and viral infections. Wrinkles and skin thickness, early signs of aging in Caucasians, are less evident in Asian skin. However, pigmentary changes occur earlier. Additionally

being the most sought-after procedures. When treating this cohort of patients, however, dermatologists need to be sensitized to how a patient's ethnicity affects facial structure, the tissue reaction to treatments, and patient's specific expectations for recommended therapies. A balance between tolerability and efficacy needs to be struck to minimize risk for adverse effects such as postinflammatory hyperpigmentation, which can negatively impact a patient's experience and quality of life.©2018

after treatment. The postinflammatory hyperpigmentation (PIH) risk was 4.7% (2 of 42, both spontaneously resolved).The 755-nm diffractive lens picosecond laser showed good efficacy and low PIH rates when treating atrophic acne scars in darker skin-type patients. In addition to treatment results, additional improvements in overall skin quality and pigmentation make the picosecond laser an effective and desirable treatment option for Asians.

65. Comparison of Q-switched Nd: YAG laser and fractional carbon dioxide laser for the treatment of solar lentigines in Asians. (PubMed)

Comparison of Q-switched Nd: YAG laser and fractional carbon dioxide laser for the treatment of solar lentigines in Asians. Solar lentigines are benign pigmented lesions that occur mostly on sun-exposed areas. Q-switched and ablative lasers are effective for removing these lesions but the high incidence of postinflammatory hyperpigmentation raises concern in darker skin types. The objective of this study is to compare the efficacy and degree of postinflammatory hyperpigmentation with the Q (...) effects were recorded.A total of 532 nm Q-switched Nd:YAG laser showed significant improvement of pigmentation over fractional CO2 laser at 6th and 12th week by both colorimeter assessment and physician grading scale (P < 0.05). No significant difference in postinflammatory hyperpigmentation from both lasers was observed. In terms of patient self-assessment, 80% of the patients treated with 532 nm Q-switched Nd:YAG laser had excellent results compared to 8% in fractional CO2 laser group. However

Advantages of darker skin include increased photoprotection, slowed aging, and a lower incidence of skin cancer. However, the increased content of melanin is associated with myriad dyschromias including melasma and postinflammatory hyperpigmentation (PIH

68. Microneedling: a new approach for treating textural abnormalities and scars. (PubMed)

Microneedling: a new approach for treating textural abnormalities and scars. Microneedling is a minimally invasive procedure wherein small holes are created across the stratum corneum while keeping the epidermis partially intact. This produces microchannels that increase skin permeability and simultaneously stimulate growth factor release. Since the epidermis is retained, microneedling has less risk of infection, postinflammatory hyperpigmentation, and scarring compared to other resurfacing

were more satisfactory for FMR. For safety profile, no significant difference was observed between two regimens, while mild postinflammatory hyperpigmentation was observed only in DL side.Both DL and FMR demonstrated efficacies for acne and seborrhoea, with reasonable safety profile. FMR was more effective than DL for the long-term maintenance, and subjective assessments for texture and scar improvements. Therefore, a few sessions of these devices would be a viable option for acne treatments.© 2017

decrease of 5.63 cm in thigh circumference; the mean decrease in fat layer thickness measured by ultrasound was 1.31 cm. The satisfaction questionnaire showed that 93.75 percent of patients were satisfied with the results. The mean visual analogue scale score was 1.66 of 10 after the session. Reversible skin changes such as postprocedure postinflammatory hyperpigmentation were observed in 8.33 percent of patients.Cryolipolysis is an effective technique for reducing saddlebag fat and is well tolerated (...) by patients. A substantial risk of skin lesions, including postinflammatory hyperpigmentation that resolved after a few months, was observed. Cryolipolysis is a good alternative to liposuction in women with moderate, well-localized saddlebags.Therapeutic, IV.

75. A Case of Facial Partial Unilateral Lentiginosis Treated with Low-Fluence 1,064 nm Q-Switched Neodymium-Doped Yttrium Aluminum Garnet Laser (PubMed)

A Case of Facial Partial Unilateral Lentiginosis Treated with Low-Fluence 1,064 nm Q-Switched Neodymium-Doped Yttrium Aluminum Garnet Laser Partial unilateral lentiginosis (PUL) is an unusual pigmentary disorder characterized by numerous lentigines grouped within an area of normal skin. Although treatment is not necessary, many patients with facial PUL seek medical help for cosmetic reasons. There is no established standard treatment for PUL. Conventional lasers may cause postinflammatory (...) hyperpigmentation because keratinocytes are injured during the process. Also, scarring, long downtime, and pain are important issues. A 19-year-old patient with facial PUL was successfully treated with low-fluence 1,064-nm Q-switched neodymium-doped yttrium aluminum garnet (QS Nd:YAG) laser. Although the exact mechanism by which low-fluence 1,064-nm QS Nd:YAG laser improves pigmentary lesions is unclear, the terms "subcellular selective photothermolysis" and "melanocyte apoptosis and replacement" have been

A review of melasma treatment focusing on laser and light devices. Melasma is a pigmentary disorder of unclear etiology with numerous treatment options and high recurrence rates. Laser and light therapies may be utilized cautiously as second- or third-line options for recalcitrant melasma, but low-energy settings are preferred due to the risk of postinflammatory hyperpigmentation and melasma stimulation. Commonly used lasers include the low-fluence 1064-nm Q-switched neodymium-doped yttrium

What devices to use or not use in skin of color. Lasers and light sources, as well as other energy devices, including radiofrequency, ultrasound, and cold-based therapies, can be used for treatment of aging, dyschromic, or texturally uneven skin. In patients with ethnic skin (ie, skin of color), energy devices are used more cautiously to avoid adverse events. The most common and concerning adverse event is postinflammatory hyperpigmentation.
