레이저 의학의 거장 Dr Emil Tanghetti 2019 대한피부모발레이저 학회 Special Speaker 참여
2019년 5월 19일(일) 대한레이저피부모발학회 제31차 춘계학술대회가 서울 삼성동 그랜드 인터콘티넨탈 파르나스에서 성황리에 개최되었습니다.
과학적, 임상적 근거가 있는 의료기기 사용을 주장하고 입증된 유명 레이저를 사용한 임상 치료 경험이 많은 세계적인 전문가 에밀 탕게티 박사는,
이번 춘계 학회에서는 해외 연자 특별 강연자로 초청되어 '피코 세컨드 레이저(피코 레이저)'에 대해 강연을 해주셨습니다.
PICOSECOND LASERS FOR MEDICAL USES AND FOR REJUVENATION
KEY WORDS- Fractional Picosecond Resurfacing, LIOB, Nevus of Ota, Skin Lightening, Laser Toning, Skin Rejuvenation, Photodamage
The picosecond Alexandrite laser was the first picosecond device developed for tattoo removal.
It was a remarkable improvement over the existing nanosecond technology for this indication. However, soon after its introduction physicians in Korea were the first to use this device to treat Nevus of Ota and facial dyspigmentation with better clearance than the older devices.
The introduction of the diffractive lens array which produced areas of laser induce optical breakdown (LIOB). This unique localized epidermal injury gradually removed unwanted epidermal pigment in patients with photodamage and melasma. It produced a generalized lightening of the skin with improvement in pore size as well as fine lines and wrinkles.
Acne scars have been noted to improve with the production of new collagen and elastic tissue. Providers found that this fractional picosecond technology provided better results and less side effects than the older Q-switched devices.
More recently there have been a number of picosecond Nd:YAG laser producing energy at 532 nm and 1064 nm with flat and fractional optics introduced to the Korean market. They have been used for the same indications as the picosecond Alexandrite laser. Unfortunately, there a few publications documenting and validating their efficacy.
The fractional optics used with these devices include a holographic optic and a refractive lens array. They do produce LIOB’s in the epidermis and superficial dermis which can in some instances can result in short lived areas of hemorrhage.
In conclusion, the picosecond laser have resulted in improved efficacy in the treatment of tattoos and with the fractional optics have resulted in a new opportunities for minimal down-time facial rejuvenation with virtually no side effects.
