Abstract

Background

Skin type has a strong influence on how sensitive skin develops, with oily skin accounting for a larger proportion of sensitive skin. However, there has not been a scientifically sound questionnaire for determining oily sensitive (OS)-type skin in prior studies.

Objectives

In order to identify OS-type skin in the general population, we therefore intend to create an OS-type skin evaluation questionnaire, develop various thresholds through data analysis and classify skin based on two dimensions of sensitivity and oiliness.

Methods

A questionnaire with questions regarding subjects' basic information, skin oiliness and skin sensitivity was given to each individual who participated in the study (n = 1297). To define the thresholds for OS-type skin, receiver-operating characteristic (ROC) curves were generated. The results of the lactic acid stinging test (LAST) and noninvasive instrument information obtained were compared with the thresholds mentioned above to verify the effectiveness of this tool.

Results

According to the ROC curves, questionnaire cut-off values of 11.5, 20.5 and 29.5 can be used to detect mildly, moderately and severely sensitive skin, respectively. In addition, the questionnaire cut-off values of 22.5 and 31.5 can be used to detect moderately and severely oily skin, respectively. According to our study, the four sensitive-skin groups' LAST scores differed significantly from one another, while the skin sebum levels differed significantly between the three oily groups. Additionally, the EI and LAST scores were significantly correlated with skin sensitivity levels, whereas sebum, moisture and EI were positively correlated with skin oiliness levels.

Conclusions

We developed an OS-type skin evaluation questionnaire that has been tested and shown scientifically to be a promising method for evaluating OS-type skin and to completely examine the traits of sensitive and oily skin.

开发并验证用于评估油性敏感皮肤的前瞻性问卷。

背景：皮肤类型对敏感性皮肤的形成有很大影响，油性皮肤在敏感性皮肤中所占比例较大。然而，在以往的研究中，还没有一份科学合理的问卷来确定油性敏感（OS）型皮肤：因此，为了在普通人群中识别油性敏感型皮肤，我们打算制作一份油性敏感型皮肤评估问卷，通过数据分析制定各种阈值，并根据敏感度和油性度两个维度对皮肤进行分类：方法：向每位参与研究的受试者（n = 1297）发放一份调查问卷，内容包括受试者的基本信息、皮肤油腻程度和皮肤敏感度。为确定 OS 型皮肤的阈值，生成了接收器操作特征曲线（ROC）。将乳酸刺痛试验（LAST）的结果和无创仪器获得的信息与上述阈值进行比较，以验证该工具的有效性：根据 ROC 曲线，11.5、20.5 和 29.5 的问卷临界值可分别用于检测轻度、中度和重度敏感皮肤。此外，22.5 和 31.5 的问卷临界值分别可用于检测中度和重度油性皮肤。根据我们的研究，四个敏感皮肤组的 LAST 分数之间存在显著差异，而三个油性皮肤组的皮脂水平之间存在显著差异。此外，EI 和 LAST 分数与皮肤敏感程度呈显著相关，而皮脂、水分和 EI 则与皮肤油腻程度呈正相关：我们开发的 OS 型皮肤评估问卷已经过测试，科学证明它是一种很有前途的评估 OS 型皮肤的方法，可以全面考察敏感性皮肤和油性皮肤的特征。

期刊介绍： The Journal publishes original refereed papers, review papers and correspondence in the fields of cosmetic research. It is read by practising cosmetic scientists and dermatologists, as well as specialists in more diverse disciplines that are developing new products which contact the skin, hair, nails or mucous membranes. The aim of the Journal is to present current scientific research, both pure and applied, in: cosmetics, toiletries, perfumery and allied fields. Areas that are of particular interest include: studies in skin physiology and interactions with cosmetic ingredients, innovation in claim substantiation methods (in silico, in vitro, ex vivo, in vivo), human and in vitro safety testing of cosmetic ingredients and products, physical chemistry and technology of emulsion and dispersed systems, theory and application of surfactants, new developments in olfactive research, aerosol technology and selected aspects of analytical chemistry.
