Objectives : The purpose of this study is to understand the anatomical basis of the facial muscles and to apply this knowledge on the clinical practice of facial acupuncture. Methods : We searched both contemporary and the latest literatures on the practical application of facial muscle anatomy on Facial Acupuncture. Conclusions : Facial Acupuncture improves skin tone, texture and wrinkling by assisting the circulation of Ki. It stimulates the facial muscles directly to undo the stagnation of the meridians. To practice Facial Acupuncture, thorough understanding of facial anatomy is required. In this study the muscles of the head and neck, appropriate depth and angle of acupuncture needle, etc. were reviewed. The upper facial muscles including frontalis, procerus, corrugator supercilii and orbicularis oculi, the mid facial muscles including auricularis, nasalis, levator labii superioris, zygomaticus and so on, and the lower facial muscles including orbicularis oris, depressor labii inferioris, depressor anguli oris, mentalis and platysma etc. were reviewed in this study. For safer and more effective use of Facial Acupuncture, further study on the objective outcome of the technique should be done.

In addition to its typical use for skin rejuvenation, fractional laser irradiation of early cancerous lesions may reduce the risk of tumor development as a byproduct of wound healing in the stroma after the controlled injury. While fractional ablative lasers are commonly used for cosmetic/aesthetic purposes (e.g., photorejuvenation, hair removal, and scar reduction), we propose a novel use of such laser treatments as a stromal treatment to delay tumorigenesis and suppress carcinogenesis. In this study, we found that non-ablative fractional laser (NAFL) irradiation may have a possible suppressive effect on early tumor growth in syngeneic mouse tumor models. We included two syngeneic mouse tumor models in irradiation groups and control groups. In the irradiation group, a thulium fiber based NAFL at 1927 nm was used to irradiate the skin area including the tumor injection region with 70 mJ/spot, while no laser irradiation was applied to the control group. Numerical simulation with the same experimental condition showed that thermal damage was confined only to the irradiation spots, sparing the adjacent tissue area. The irradiation groups of both tumor models showed smaller tumor volumes than the control group at an early tumor growth stage. We also detected elevated inflammatory cytokine levels a day after the NAFL irradiation. NAFL treatment of the stromal tissue could potentially be an alternative anticancer therapeutic modality for early tumorigenesis in a minimally invasive manner.

레티노이드 효과가 나타나는 것을 목적으로 하여 다양한 히드록삼산 유도체를 합성하였고, 레티노익산 수용체에 대한 전사 활성을 측정하여 스크리닝하였다. 합성된 화합물 중에서 N-(4-N-hydroxycarbamoyl)phenyl) [4-(tort-butyl)phenyl] carboxamide (2f)가 수용체에 대한 가장 강력한 적합성을 나타내었다. 히드록삼산 구조에서 산도를 나타내는 히드록시기는 쉽게 이온화하여 음이온을 형성한다. 형성된 히드록삼산의 음이온은 레티노익산의 음이온과 유사한 역할을 한다. 이와 같이 히드록삼산 화합물이 레티노이드 효과를 나타내는 예는 이전에 알려진 바가 없다. 화합물 2f의 레티노이드 효과는 레티노이드와 연관된 유전자의 발현 증가 효과로 한번 더 검증하였다. 노화 원료로서의 가능성을 확인하기 위해서 MMP-1의 발현 억제능을 레티노익산, 레티놀과 비교하여 살펴보았다. 10 uM 농도에서 화합물 2f는 MMP-1의 발현을 억제하였다. 이와 같은 결과로 화합물 2f는 항노화 원료로서의 가능성을 가지고 있다.
