At present, there is a lack of baseline data on the facial skin biophysical profile of women in Malaysia. The implications related to the daily habits and facial skincare product use on the skin biophysical condition are, thus, unknown. In this study, we aim to evaluate facial skin biophysical parameters of Malaysian women and examine the influence of demographic characteristics, daily habits, and facial skincare product use on these parameters.
Four skin biophysical parameters - transepidermal water loss (TEWL), melanin content, elasticity, and collagen intensity - were assessed on the cheek of the subjects (20-60 years). Demographic background, daily habits, and skincare product use were gauged through a survey. Only 197 from the 213 subjects recruited initially were used for analysis after the data were screened for normality.
The biophysical parameters were similar in different races, except a higher melanin content in Indian female individuals. Elasticity and collagen intensity reduced with age, while melanin content increased in the older age-groups. But no difference was observed in TEWL at different ages. Evaluating the influence of daily habits, we observed that exercise significantly lowered TEWL and increased melanin content, which may be associated with UV radiation exposure. Facial skincare products are popular among the female subjects (>85% users). Products with moisturizing, sunscreening, and other skincare functions (astringent, antiaging, and anti-wrinkle) were preferred by subjects of all ages. These product functions significantly improve skin elasticity and reduce melanin content in the young adults. While aged women recognized the importance of having an additional skin-lightening function in their skincare routine. Although the influence of individual skincare function on skin biophysical parameters was mostly positive, the alteration of these parameters varied at different ages.
This is the first report of facial skin biophysical profile of Malaysian women. There is no difference among 3 major races saved for melanin content. This work demonstrated age-dependent influences on the biophysical parameters, except TEWL. The significance of skincare product use is well reflected in the improvement of these parameters at different age-groups based on individual skincare functions.
目前,马来西亚女性面部皮肤生物物理特征尚缺乏基础数据。因此,日常生活习惯和面部护肤产品使用对面部皮肤生物物理状况的影响尚不清楚。本研究旨在评估马来西亚女性的面部皮肤生物物理参数,并研究人口统计学特征、日常生活习惯和面部护肤产品使用对这些参数的影响。
在研究对象的脸颊上评估了 4 项皮肤生物物理参数 - 经表皮水分流失(TEWL)、黑色素含量、弹性和胶原蛋白强度。通过问卷调查评估人口统计学背景、日常生活习惯和护肤品使用情况。在对数据进行正态性筛选后,最初招募的 213 名受试者中只有 197 名用于分析。
除了印度女性个体的黑色素含量较高外,不同种族之间的生物物理参数相似。随着年龄的增长,弹性和胶原蛋白强度降低,而黑色素含量在较年长的年龄组中增加。但是,不同年龄组的 TEWL 没有差异。评估日常生活习惯的影响时,我们发现运动显著降低了 TEWL 并增加了黑色素含量,这可能与紫外线辐射暴露有关。面部护肤产品在女性研究对象中很受欢迎(>85%的使用者)。具有保湿、防晒和其他护肤功能(收敛、抗衰老和抗皱)的产品受到各年龄段研究对象的喜爱。这些产品功能可显著改善年轻人的皮肤弹性并降低黑色素含量。而年长的女性则认识到在护肤程序中具有皮肤增白功能的重要性。尽管个别护肤品功能对皮肤生物物理参数的影响大多是积极的,但这些参数在不同年龄段的变化有所不同。
这是马来西亚女性面部皮肤生物物理特征的首次报告。除黑色素含量外,3 大主要种族之间没有差异。本研究表明,除 TEWL 外,年龄对生物物理参数有影响。基于个别护肤功能,在不同年龄组中,护肤品使用对面部皮肤生物物理参数的改善情况充分反映了其重要性。
