The Asian dermatologic patient: review of common pigmentary disorders and cutaneous diseases.

摘要: The Asian patient with Fitzpatrick skin types III–V is rarely highlighted in publications on cutaneous disorders or laser surgery. However, changing demographics, Asians will become an increasingly important group this context. Although high melanin content confers better photoprotection, photodamage the form of pigmentary common. Melasma, freckles, and lentigines are epidermal commonly seen, whilst nevus Ota acquired bilateral Ota-like macules common dermal disorders. Post-inflammatory hyperpigmentation (PIH) occurring after injury remains a hallmark color. With increasing use lasers light sources Asians, prevention management PIH great research interest. Bleaching agents, chemical peels, intense pulsed (IPL) treatments, fractional resurfacing have all been used some success for melasma. Q-switched (QS) effective pigmentation but associated risk PIH. Long-pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG) IPL pose less require greater number treatment sessions. Dermal targeted by QS ruby, alexandrite, 1064-nm Nd:YAG lasers, hyper- hypopigmentation may occur. Non-ablative rejuvenation using combination approach different conjunction cooling devices allows chromophores to be optimal results achieved, even Deep-tissue heating radiofrequency infra-red affects deep dermis achieves enhanced tightening, resulting eyebrow elevation, rhytide reduction, contouring lower face jawline. For severe degrees photoaging, useful wrinkle pigment as well acne scarring.
