“…Other investigators have similarly observed that pigmentary changes occur with a greater incidence than skin wrinkling in Asians. [4] Other cutaneous manifestations of aging ethnic skin include the development of benign cutaneous growths such as dermatosis papulosa nigra, seborrheic keratoses, and the development of solar lentigines. However, moderate-to-severe wrinkling becomes apparent only at about 50 years of age, which is a decade or two later than in age-matched Caucasians.…”

The Asian patient with Fitzpatrick skin types III-V is rarely highlighted in publications on cutaneous disorders or cutaneous laser surgery. However, with changing demographics, Asians will become an increasingly important group in this context. Although high melanin content confers better photoprotection, photodamage in the form of pigmentary disorders is common. Melasma, freckles, and lentigines are the epidermal disorders commonly seen, whilst nevus of Ota and acquired bilateral nevus of Ota-like macules are common dermal pigmentary disorders. Post-inflammatory hyperpigmentation (PIH) occurring after cutaneous injury remains a hallmark of skin of color. With increasing use of lasers and light sources in Asians, prevention and management of PIH is of great research interest. Bleaching agents, chemical peels, intense pulsed light (IPL) treatments, and fractional skin resurfacing have all been used with some success for the management of melasma. Q-switched (QS) lasers are effective for the management of epidermal pigmentation but are associated with a high risk of PIH. Long-pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG) lasers and IPL sources pose less of a PIH risk but require a greater number of treatment sessions. Dermal pigmentary disorders are better targeted by QS ruby, QS alexandrite, and QS 1064-nm Nd:YAG lasers, but hyper- and hypopigmentation may occur. Non-ablative skin rejuvenation using a combination approach with different lasers and light sources in conjunction with cooling devices allows different skin chromophores to be targeted and optimal results to be achieved, even in skin of color. Deep-tissue heating using radiofrequency and infra-red light sources affects the deep dermis and achieves enhanced skin tightening, resulting in eyebrow elevation, rhytide reduction, and contouring of the lower face and jawline. For management of severe degrees of photoaging, fractional resurfacing is useful for wrinkle and pigment reduction, as well as acne scarring. Acne, which is common in Asians, can be treated with topical and oral antibacterials, hormonal treatments, and isotretinoin. Infra-red diode lasers used with a low-fluence, multiple-pass approach have also been shown to be effective with few complications. Fractional skin resurfacing is very useful for improving the appearance of acne scarring. Hypertrophic and keloid scarring, another common condition seen in Asians, can be treated with the combined used of intralesional triamcinolone and fluorouracil, followed by pulsed-dye laser. Esthetic enhancement procedures such as botulinum toxin type A and fillers are becoming increasingly popular. These are effective for rhytide improvement and facial or body contouring. We highlight the differences between Asian skin and other skin types and review conditions common in skin of color together with treatment strategies.

Beauty has been appreciated throughout our evolution and is responsible for the propagation of our species. Perhaps, controversially, it is the most important trait that we have. The appearance of our skin and the presentation of uniformity in color, texture, and the reflection of light in a smooth and nonabrupt manner as it flows from one anatomical location to another play a major role in facial beauty. 1 With the relatively recent explosion of the cosmetic industry and the ease with which our information is being disseminated (i.e., the Internet and computers), our knowledge and options are increasing. These have evolved to the present day where we have multiple methods to choose from: chemical peels (salicylic, Jessner's Solution, trichloroacetic acid [TCA], glycolic, resorcinol, lactic acid, etc.), dermabrasion, dermarolling, dermasanding, laser resurfacing (carbon dioxide [CO 2 ], erbium:yttrium aluminum garnet [Er:YAG], etc.), the fractional application of laser resurfacing, and nonablative/ablative combinations.Lasers, Peels, and Abrasion Techniques for East Asian Skin

Background and ObjectivesFractional radiofrequency devices have been demonstrated to improve skin texture, such as smoothness, rhytides, brightness, and atrophic acne scars, by increasing dermal thickness, dermal collagen content, and dermal fibrillin content. The objective of the study is to assess the efficacy and adverse effects of this device on Asian patients of skin type III and IV with skin textural changes.Materials and MethodsThe study was designed as a prospective, open‐labeled single‐arm study, which was conducted with 20 Chinese patients aged 21–60 years and having irregularities in their skin texture, rhytides, and acne scars. The patients received six treatments at intervals of 4 weeks. Treatment was initiated with the maximum energy tolerated, which was then adjusted during the course of treatment if the patients felt excessive discomfort. A total of two passes were delivered in each session. Physician assessment results and standardized photographs were collected at the baseline, after all treatment visits, and at 1, 2, and 6 months after the final treatment visit.ResultsA total of 17 patients completed the study according to the established protocol. At the 6‐month follow‐up, 71% of patients were satisfied and 24% of patients were very satisfied with the received treatments, and the treatment physician reported varying degrees of improvement based on the global assessment scale in 60% of the subjects. While the anticipated side effects, such as erythema, edema, pinpoint bleeding, scab formation, and flare of acne, were noted in the patients, no serious adverse effects occurred.ConclusionThe use of fractional radiofrequency improves skin texture and is safe for use in Asian patients of skin type III and IV. No long‐term serious adverse effects were noted.
