Lipid Profiling of Oily Skin in Chinese Female aged 22-28 and 29-35 Defined by the Life Rhythm Theory of Huangdi Neijing
«황제내경》의 생체리듬이론으로 정의된 22-28세 및 29-35세 중국 여성의 지성 피부에 대한 지질 프로파일링
Purpose: According to the life rhythm derived from the ancient Chinese medicine book Huangdi Neijing, female growth and development culminates between the age of 22-28, with strong muscles, bones and vigorous hair. To investigate the characteristics of facial lipid profile in oily skin of female at different developmental stages classified based on seven-year rhythm, and to provide the mechanistic insight into the aging theory of Huangdi Neijing. Methods: The facial lipid composition of two groups of healthy women with oily skin (O1 group: age of 22-28; O2 group: age of 29-35) was analyzed by ultra-performance liquid chromatography-quadrupole tandem time-of-flight mass spectrometry (UPLC-QTOF-MS). Differential lipids between O1 and O2 groups were identified using an orthogonal partial least squares discriminant analysis (OPLS-DA) model. Results: No significant difference in skin barrier function was found between the O1 and O2 groups. In contrast, skin elasticity and skin radiance displayed significant changes, with the O2 group showing decreased skin elasticity and dull skin, which is consistent with the description in Huangdi Neijing. In terms of lipid profile, among eight lipid main classes, seven lipid classes [FA], [GL], [GP], [PK], [PR], [SP] and [ST] showed significantly higher relative levels in the O2 group (p<0.05). Among the differential lipid species, myriocin, erucamide, phosphatidylserine, flavonoid compounds, and sphinganine were significantly and negatively correlated with skin elasticity (R2) and skin radiance (ITA) (p<0.05). Conclusion: The seven lipid species identified are important for targeting markers of skin aging and developing cosmetics that maintain skin elasticity and color.

목적: 고대 중국 의학서인 《황제내경》에 나오는 생활 리듬에 따르면 여성의 성장과 발달은 22-28세 사이에 정점에 이르며 근육 과 뼈가 튼튼하고 머리카락이 풍성하고 튼튼하다. 여칠남팔(女七男八) 주기에 따라 분류된 다양한 발달 단계에서 여성 지성 피부 의 안면 지질 특성을 조사하고 황제내경의 노화 이론에 대한 기계적 통찰력을 제공하고자 한다. 방법: 초고성능 액체 크로마토그 래피-4중극자 탠덤 비행 시간질량분석(LC-QTOF-MS)를 이용하여 두 그룹의 건강한 지성 피부 여성(O1 그룹: 22-28세; O2 그룹: 29-35세)의 얼굴 지질 구성을 분석하였다. O1과 O2 그룹 간의 차등 지질은 직교부분최소자승판별(Orthogonal Partial Least Squares Discriminant Analysis, OPLS-DA) 모델을 사용하여 식별하였다. 결과: O1군과 O2군 사이에 피부 장벽 기능에는 유의미 한 차이가 발견되지 않았다. 이에 반해, 피부 탄력과 피부 광채는 유의미한 변화를 보였으며, O2군에서는 피부 탄력이 감소하고 피 부가 칙칙하였으며, 이는 황제내경의 설명과 일치하다. 지질 프로필 측면에서 볼 때, 8개의 주요 지질 클래스 중 7개의 지질 클래스 [FA], [GL], [GP], [PK], [PR], [SP] 및 [ST]의 상대 수준은 O2그룹이 O1그룹에 비해 유의하게 높았다(p<0.05). 차등 지질 종 중에서 미리오신, 에루카미드, 포스파티딜세린, 플라보노이드 화합물 및 스핑가닌은 피부 탄력(R2) 및 피부 윤기(ITA)와 유의미하게 음의 상관관계를 나타냈다(p<0.05). 결론: 이상 확인된 7가지 지질종은 피부 노화 지표의 표적으로써, 피부 탄력과 얼굴빛을 유지하는 화 장품 개발에 매우 중요한 의미가 있다.
