61. Noninvasive Atrophic Acne Scar Treatment in Asians With a 755-nm Picosecond Laser Using A Diffractive Optic Lens-A Retrospective Photographic Review. (Abstract)

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.

63. Prurigo Pigmentosa: A Clinicopathological Report of Three Middle Eastern Patients Full Text available with Trip Pro

Prurigo Pigmentosa: A Clinicopathological Report of Three Middle Eastern Patients Prurigo pigmentosa is a unique cutaneous inflammatory disorder characterized by a sudden onset of pruritic and erythematous macules, urticarial papules, and plaques that may coalesce to form a reticulated pattern. Lesions typically heal within weeks leaving a reticulated and mottled postinflammatory hyperpigmentation. The majority of reported cases originate from Japan with much fewer cases described worldwide

, 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

65. "Treatment of Facial Hypopigmented Scars by the Laser Hole Technique using a Non-fractional Carbon Dioxide Laser in Asian". (Abstract)

"Treatment of Facial Hypopigmented Scars by the Laser Hole Technique using a Non-fractional Carbon Dioxide Laser in Asian". Facial hypopigmented scars are usually characterized by white color and a glossy surface. To correct the two problems simultaneously, the authors attempted to induce persistent postinflammatory hyperpigmentation for color and to build multiple pitted scars like facial skin pores for texture. This study describes a laser hole method using a traditional nonfractional carbon (...) or 2 months after initial treatment, the remaining hypopigmentation was treated by the same procedure.Treatment sessions were performed once for nine scars, twice for 22 scars, and three times for 12 scars. In most cases, postinflammatory hyperpigmentation was slightly diminished but maintained until the last follow-up. The fine irregular surface with multiple pitted scars was similar to that of normal skin. Scar improvement evaluation showed marked or excellent in 39 scars (90.7 percent

Ablative fractional carbon dioxide laser combined with intense pulsed light for the treatment of photoaging skin in Chinese population: A split-face study. Intense pulsed light (IPL) is effective for the treatment of lentigines, telangiectasia, and generalized erythema, but is less effective in the removal of skin wrinkles. Fractional laser is effective on skin wrinkles and textural irregularities, but can induce postinflammatory hyperpigmentation (PIH), especially in Asians. This study

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

radiation. However, overproduction of melanin, in addition to altering the appearance of skin, may lead to skin disorders such as melasma, solar lentigo, and postinflammatory hyperpigmentation. Previous studies have revealed that sesamol is a strong antioxidant and a free radical scavenger. In this study, we investigated the effects of sesamol on the regulation of melanogenesis and related mechanisms in B16F10 cells. The results indicated that sesamol inhibited tyrosinase activity and melanogenesis

71. Microneedling: a new approach for treating textural abnormalities and scars. (Abstract)

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

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

80. A Case of Facial Partial Unilateral Lentiginosis Treated with Low-Fluence 1,064 nm Q-Switched Neodymium-Doped Yttrium Aluminum Garnet Laser Full Text available with Trip Pro

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
