ph值被认为是表皮屏障功能和体内平衡的重要参数。目的探讨年龄和身体部位对女性皮肤表面pH值（pH SS）的影响。方法采用发光传感器箔的时域双寿命参比法测量pH SS。测定成年女性前额、太阳穴、前臂掌侧的pH SS （n= 97, 52.87±18.58,20 ~ 97岁）。由于使用了发光成像技术，每次测量都包含2500个pH值。结果3个身体部位的sph SS随年龄的增长略有增加。在三个被调查的身体部位之间，pH和SS没有显著差异。结论成人前额、太阳穴、前臂掌侧pH值随年龄增长略有增加。这一知识对于调整医疗护肤产品至关重要。
BackgroundpH is known as an important parameter in epidermal barrier function and homeostasis.AimThe impact of age and body site on skin surface pH (pH SS) of women was evaluated in vivo.MethodsTime domain dual lifetime referencing with luminescent sensor foils was used for pH SS measurements. pH SS was measured on the forehead, the temple, and the volar forearm of adult females (n= 97, 52.87±18.58 years, 20–97 years). Every single measurement contained 2,500 pH values due to the luminescence imaging technique used.ResultspH SS slightly increases with age on all three investigated body sites. There are no significant differences in pH SS between the three investigated body sites.ConclusionAdult pH SS on the forehead, the temple and the volar forearm increases slightly with age. This knowledge is crucial for adapting medical skin care products.
