Effects of Various Soap Elements on Skin

Abstract

To elucidate the effects of sea salt and various other soap ingredients on skin in humans. Methods: Forty healthy women (age 30.4 ± 6.0 years) were assigned to one of four test-soap groups (sea salt, SS; collagen added, SS+C; humic added, SS+H; or, fucoidan added, SS+F) or a control group. Subjects washed their face with the soap twice daily for eight weeks. Before and after the study, subjects undertook the Anti-Aging QOL Common Questionnaire (AAQol), skin image analysis (VISIAII), elasticity tests by a Cutometer (MPA580), and moisture tests by a Corneometer (CM825). Results: At 8 weeks, significant improvements were seen in symptoms scores for "noticeable blackheads in pores" and "oily face" in the SS group, the score for "concerned about spots or freckles" in the SS+H group, and the scores for "noticeable pores", "concerned about pore opening", "dry skin", "rough skin", "concerned about rough skin", and "corner of eyes sagging" in the SS+F group. There was no significant change in skin moisture. Compared to controls, the R2 index of skin elasticity showed improvement in the SS+C group by inter-group analysis (p=0.009). On skin image analysis, the number of face wrinkles bilaterally (-26.6%, p=0.008) in the SS+F group and the number of wrinkles on the right side of the face (-45.5%, p＝0.005) in the SS group) showed significant improvement. Although an increase in ultraviolet (UV) spots was seen in the SS and control groups, this increase was significantly attenuated in the SS+C group (inter-group analysis: p<0.05). Further, compared to controls, there was a significant reduction in the number of red spots in the SS+H group (number：-7.9%, p＝0.022, % area：-11.7%, p=0.039). No severe adverse effects were observed during this study. Conclusion: An improvement in wrinkles was seen in the SS group, with different additional elements displaying benefits in different areas of skin appearance and health. The SS+C group showed beneficial results with regard to elasticity and UV spots, the SS+H group showed beneficial results in red spots, and the SS+F group showed beneficial results in moisture levels and wrinkles.

Tolerability and hydrating effects of an anti-aging gynaecological collagen cream in women in menopause

“…The improvement in skin moisturising was statistically significant at the abdominal skin application site. The results of the present study are consistent with the literature data [37][38][39][40][44][45][46][47][48]. In particular, the results are consistent with those of Li et al [44], who also showed that the measures taken one hour of the application are predictive of the stratum corneum moisturising obtained after a multiple applications for one or 2 weeks.…”

“…Results obtained for perineal and abdominal skin viscoelasticity were consistent with previously published data of other similar studies [29,[45][46][47][48]. In the present study, small changes in the skin elasticity parameters were observed in both perineal and abdominal skin, but their majority did not have statistical significance.…”
