However, hand hygiene compliance is often hindered by a number of factors, one of which is irritant contact dermatitis. Illustrating the benefits of skin friendly hand disinfectants and their effect on skin condition could positively influence hand hygiene compliance. The aim of this study was to analyse the skin hydrating effect of a hand disinfectant with a comprehensive skin care complex using Capacitive Contact Imaging (CCI) as a method to assess and visualise skin hydration in comparison to conventional corneometry. In addition to established parameters, including pH value, transepidermal water loss (TEWL), and dermatological assessments, the study investigated the dermatological effects of a two-week application of a hand disinfectant foam. Frequent daily application of the product led to an improvement in skin hydration without causing intolerability. The results from CCI and corneometry were consistently comparable and showed significantly elevated skin hydration after the two-week application period. CCI illustrated the increased skin hydration and it’s potential to be used as an additional method to evaluate and demonstrate the effect of hand hygiene products on skin health.

Objective and subjective reduction of cellulite volume using a localized vibrational massage device in a 24-week randomized intra‐individual single-blind regression study / Tomasz Sadowski in INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Vol. 42, N° 3 (06/2020)

Cellulite Etude in vivo Massage vibratoire Profilométrie Index. décimale : 668.5 Parfums et cosmétiques Résumé : Cellulite occurs in females and is a common condition of altered connective tissue matrix and increased adipogenicity with visible dimples and orange-peel appearance on the skins surface. Whilst advancements in methods continue to help our understanding, attempts to correct the appearance of cellulite topically have yielded limited success. Various kinds of non-invasive body contouring methods such as whole body vibration have been reported with demonstrable visible improvements in the cellulite condition. The aim of this study was to evaluate volume reduction and improvement of the visible appearance of cellulite as judged both objectively (AEVA-HE phase-shift 3-D fringe projection, macrophotography image grading) and subjectively (questionnaires) after application of a hand-held localized vibrational device over 24-weeks. The study was conducted on 40 healthy female volunteers who were instructed how to use the device on defined areas of cellulite of the outside and rear of the thighs (iliotibial band, and over biceps femoris region respectively). The initial 12 weeks of continuous massage application of the study were followed by a 12 week phase in which volunteers were split into 2 subgroups – one for assessment of regression effects and one for continuous application effects. AEVA (skin surface volume) measurements of cellulite-related dimples correlated with questionnaires and visual image evaluation scoring, in that in the iliotibial region cellulite was significantly reduced at 12 weeks. In the regression subgroup cellulite returned to initial values soon after cessation of treatment, whereas in the continuous application subgroup, cellulite remained diminished. The effect of this device to reduce cellulite as observed in this study proves that continuous use of vibrational massage is beneficial to mitigate visible signs of cellulite.
