Abstract. A number of noninvasive techniques and instruments have emerged over the years allowing much progress toward clarifying the structure and function of human skin and studying the effects of various applied substances. All of this research has provided great insight into the interactions between skin and various products through quantitative and qualitative measurements. Such methods include near-infrared spectroscopy (NIRS), a technique which has gained popularity over the years and has often been employed to accurately determine the moisture levels and water content of skin based on its sensitivity to hydrogen bonding. NIRS has also been applied in many studies to report the efficacy of moisturizing products and assess their benefits to the skin. However, many of these studies have reported an increase in skin water content following moisturizer application while some have challenged the benefits of long-term moisturizer use, particularly on normal skin, and even suggested that it can increase the skin's susceptibility to irritants. This paper reports the results of a pilot in vivo study carried out on the skin of 20 healthy volunteers, categorized into groups depending on their skin type and frequency of moisturizer use, in order to investigate the optical response of human skin after direct short-term contact with water followed by application of a moisturizer. The measurements were obtained using a highly advanced spectrophotometer in the region of 900 to 2100 nm equipped with a customized reflectance fiber optic handheld probe. Scatter graphs of group results and second derivative spectra have shown an interesting pattern between frequent users of moisturizers and individuals who do not use moisturizers, suggesting that long-term daily moisturization may have an effect on skin barrier function. The results also raise some questions regarding the optical characteristics of different skin types, as well as the varying response between different water bands in the NIR region. Future work will focus on gaining more knowledge about these subjects and obtaining results from a larger population, as well as performing statistical analysis through regression methods in order to further improve optical skin measurements.

“…NIR Spectroscopy is a non-invasive, effective, simple and inexpensive technique that has been suggested for clinical assessment of body composition 21,22,23,24,25 . Besides that, in dermatological field, this technique is widely used such as for determination of skin moisture content 26,27,28,29 . Research on human skin sebum using spectroscopic measurement also has been conducted.…”

There are many techniques and instruments that are currently available to give better results for measuring the quality of human skin. In this study, two non-invasive spectroscopy instruments have been used namely NIRQuest spectrometer and ASD FieldSpec® 3 Spectroradiometer. Both of these spectroscopy instruments were used to find the correlation technique with the commercial instruments (DermaLab® USB Sebum Module). Initially an experiment was conducted to find intensities peak of the absorption of oleic acid as a part of sebum composition. From the spectra peak of the absorbance, the wavelength will be determined. Next step was to measure the reflectance of human skin sebum by using two spectroscopic instruments. The analysis will carry on at the wavelength that have been chosen from the previous study and also from the wavelength of the fatty acid to find the best wavelength that contribute in sebum composition. From several analyses, the wavelengths that contribute in sebum were 1208, 1414, 1726, and 1758 nm that obtained the value of R 2 0.8444 for NIRQuest Spectrometer and 0.8532 for ASD FieldSpec® 3 Spectroradiometer. For future research this non-invasive techniques can be used in dermatology field for the use of various skin analysis. Besides that, the less wavelength used is an advantage to develop instruments with less amount of wavelength sensor. It can reduce the cost of development.

“…NIR spectra can also provide additional insight regarding other skin constituents including lipids and proteins, it can differentiate between different types of water in the skin [9,10], and its instrumentation can easily be equipped with fibre optic probes for in vivo measurements. Unfortunately, a reliable instrument based on NIR spectroscopy designed specifically for skin hydration measurements is not yet available, although a few recent studies have looked at ways to improve or miniaturize this technique [12][13][14]. Results from this experiment will be used in conjunction with our previous work [15], to aid the future design and development of a portable NIR spectroscopic device that would allow accurate, fast and non invasive in vivo measurements of skin hydration and water content.…”

This is the accepted version of the paper.This version of the publication may differ from the final published version. Abstract-Nowadays, a number of noninvasive methods and instruments are available to inspect the biophysical properties and effects of various applicants on human skin, providing quantitative measurements and more details regarding the interactions between skin and various products. Such methods include Near Infrared Spectroscopy (NIRS), a technique which over the years, has gained quite a reputation in being able to accurately determine moisture levels and water contents due to its sensitivity to hydrogen bonding. This paper reports preliminary results of an in vivo study carried out on the skin of a small number of human participants, investigating the optical response of human skin after direct short-term contact with water followed by application of a moisturizer, using a highly advanced spectrophotometer in the region of 900-2100nm, and equipped with a reflectance fibre optic probe. Results obtained here certainly raise some questions regarding the optical characteristics of different skin types and the influence of frequent moisturizer use, as well as the varying response between different water bands in the NIR region. Future work will focus on gaining more knowledge about these, in order to further improve optical skin measurements, and hopefully support the design and development of a portable and/or miniaturized optical device that could provide reliable, accurate and fast skin hydration readings in real time.
