The usefulness of sebum check film for measuring the secretion of sebum

Abstract

Patients with atopic dermatitis (AD) often present with dry skin, and the reduced secretion of sebum may be responsible for the impaired skin barrier function. A sebum check film enables the patient to self-evaluate the skin sebum content. This study compared the sebum check film with a sebumeter. The skin sebum content of the forehead was measured using a sebum check film and a sebumeter. The findings of the sebum content of healthy controls showed that the sebum dot fields on the sebum check film were significantly correlated with the sebum content measured using the sebumeter (r = 0.774, p < 0.001). In addition, the sebum fields on the sebum check film of AD patients (n = 26) were significantly less than those on the sebum check film of the controls (n = 30; p < 0.05). Furthermore, the analysis of the sebum fields on the sebum check film of the AD patients was significantly correlated with their sebum content findings that were obtained using a sebumeter (r = 0.592, p < 0.01). These findings indicate that the sebum check film is easy to use for measuring the sebum secretion and is suitable for self-checking the sebum contents by AD patients for daily skin care.

Development of optical near-infrared spectroscopy instruments for human skin sebum measurement

“…As a result, the amount of reflected light varies according to the amount of sebum collected by the film. The concept that applied is the lipid absorption with tape where the film has a hydrophobic structure and absorbs only lipids, thus, this film absorbs no sweat or water 14,15,16 . Subsequent to applying the DualTape to the skin at constant time for 60s the tape strip is inserted into the DualTape Reader as in Figure 6.…”

“…This lipid absorption with tape offered a good correlation. These instruments of measuring sebum are known as Sebutape and Sebumeter 5,9,11,12,16,17,18,19,20 .…”

“…Research on human skin sebum using spectroscopic measurement also has been conducted. The instruments that used were thin-layer chromatography, UV-induced fluorescent digital imaging system and infrared reflectance spectroscopy 3,16,30 .…”

“…With the advancements in the technology, the measurement of the distribution of sebum then moved to other instruments. Sebum absorbent tape was introduced as another technique which was more reproducible and convenient for the estimation of the distribution of sebaceous gland's output 14,15,16 . The sebum absorbent tape that was made of the sebum-Test Strip, was comprised of an open-celled, microporous, hydrophobic film that was coated with an adhesive layer for the lipid to pass through it.…”

“…A avaliação por técnicas não invasivas são capazes de caracterizar as propriedades de superfície, como descamação e ressecamento (CASETTI et al, 2011), cor e pigmentação (PARK et al, 2006) e relevo e rugas (PENA FERREIRA et al, 2010); a estrutura da pele, dentre as técnicas o ultra-som de alta frequência (KIM et al, 2013) e a microscopia confocal (GONZÁLEZ; GILABERTE-CALZADA, 2008); e as funções, como superfície lipídica e produção de sebo (FURUICHI et al, 2010;DOBREV, 2007), evaporação de água e transpiração (MACHADO et al, 2010) e propriedades mecânicas (OHSHIMA et al, 2012), dentre outros parâmetros (SERUP, 2001;FRITSCH et al, 2009).…”
