Серия коротких импульсов сильнее нагревает папиллу, что приводит к более высокой временной эффективности удаления волос. Воздействие длинных одиночных импульсов вызывает более выраженное нагревание области bulge, что обеспечивает более высокую долгосрочную эффективность эпиляции.</p><sec><title>Цель работы</title><p>Цель работы. Разработать алгоритм подбора оптимальных параметров излучения диодного лазера для достижения требуемой температуры термического разрушения дермальной папиллы и области bulge при проведении эпиляции длинными импульсами и серией коротких импульсов.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Эпиляция проведена у 109 пациентов в возрасте от 20 до 80 лет длинными импульсами на толстых черных и темно-коричневых волосах с учетом глубины залегания луковицы волоса, фототипа кожи по Фитцпатрику, возраста пациента. Эпиляция выполнена с использованием диодного лазера Capello (длина волны 808 нм) производства Promoitalia (Италия). Параметры плотности энергии и длительности импульса для удаления волос подбирались с использованием построенных таблиц для определения нагрева дермальной папиллы черного волоса с глубиной залегания 3,5– 4,5 мм (светлая кожа). Длительность импульса составляла 60–150 мс, плотность энергии 60–120.</p></sec><sec><title>Результаты</title><p>Результаты. После проведения 7–9 процедур по удалению толстых черных волос на голени, бедре, подмышках, подбородке, плече и предплечье, лобковой зоне, при контрольном осмотре через полгода и 1 год после окончания цикла процедур выявлены единичные волосы (не более 1%) во всех зонах воздействия.</p></sec><sec><title>Заключение</title><p>Заключение. Построенные таблицы могут быть использованы для определения оптимальных параметров одиночного импульса (длительности и плотности энергии) с целью обеспечения необходимой температуры теплового разрушения как дермальной папиллы, так и области bulge толстых черных волос с глубиной залегания 3,5–4,5 мм.</p></sec></abstract><trans-abstract xml:lang="en"><p>In the present work it has been shown that long single pulses and a series of short pulses with the same exposure duration and total energy density heat the dermal papilla and the bulge area differently. A series of short pulses produces more heat in the papilla what makes temporal hair removal more efficient. Exposure to long single impulses causes a more pronounced heating of the bulge area what provides better long-term effectiveness of epilation.</p><sec><title>Purpose</title><p>Purpose. To develop an algorithm for selecting optimal parameters of diode laser irradiation so as to achieve the required temperature level for thermal destruction of the dermal papilla and the bulge area during epilation with long pulses and a series of short pulses.</p></sec><sec><title>Material and methods</title><p>Material and methods. Epilation with long pulses was performed in 109 patients aged 20–80 having thick black and dark brown hair. The researchers took into account the depth of hair follicle location, Fitzpatrick skin phototype, patient’s age. Epilation was performed with Capello diode laser (wavelength 808 nm) manufactured by Promoitalia Ltd. (Italy). Parameters of energy density and pulse duration for hair removal were selected using the developed tables to determine the heating intensity of dermal papilla of black hair with its depth of 3.5–4.5 mm (fair skin). Pulse duration was 60–150 ms, energy density was 60–120 J /cm2.</p></sec><sec><title>Results</title><p>Results. After 7–9 sessions of thick black hair removal on the shin, thigh, armpits, chin, shoulder and forearm as well as on the pubic area, control examination in half a year and in one year detected only isolated hairs (not more than 1%) in all treated zones.</p></sec><sec><title>Conclusion</title><p>Conclusion. The developed tables can be used to determine optimal parameters (exposure duration and energy density) for a single impulse in order to achieve necessary temperature level to get thermal destruction of both dermal papilla and bulge area in patients with thick black hair and depth of 3.5–4.5 mm.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эпиляция</kwd><kwd>диодный лазер</kwd><kwd>дермальная папилла</kwd><kwd>область bulge</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hair removal</kwd><kwd>diode laser</kwd><kwd>dermal papilla</kwd><kwd>bulge area</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Левкович А.В., Мельник В.С.
