Bottom Line: After single application, significant increase has been observed in both the skin electrical (P < 0.001) and mechanical properties (P < 0.01) as compared to the control, at which no products were applied.After the 3-week period, both effects are maintained and found to be significant at P < 0.001.Short- and long-terms study revealed the best performing herbal moisturizer.

ABSTRACT

Background: A number of moisturizers are available containing natural hydrating, moisturizing, fi rming and occlusive property-imparting agent in the form of herbal extracts, juice and oils. The aim of this study is to assess the hydration and viscoelastic effect of commercially available herbal moisturizers, containing different herbs, on human skin, after a single and 3-week period of application using skin bio mechanical and electrical techniques.

Materials and methods: Twenty selected herbal moisturizers (HM) were coded as HM1-HM20. Forty volunteers, mean age of 40 ± 9 years, were participated in the short- and long-term study. Skin properties in terms of hydration and viscoelastic parameters were measured by multitester and cutometer, respectively. Measurements were done before and after 1, 2, and 3 h (single application) and for the 3-week period of daily application.

Results: After single application, significant increase has been observed in both the skin electrical (P < 0.001) and mechanical properties (P < 0.01) as compared to the control, at which no products were applied. After the 3-week period, both effects are maintained and found to be significant at P < 0.001. Short-and long-term study revealed that out of 20 herbal moisturizers, HM8 and HM10 show pronounced increase in skin hydration (90-100%) and HM8, HM10, and HM11 shown marked increase in skin viscoelasticity (90-95%).

Conclusion: The possible reason of maximum effects obtained by these products is multifunctional effects of active ingredients of incorporated herbs. Combined used of both non invasive techniques is useful to substantiate the hydrating and viscoelasticity claim of herbal moisturizer. Short- and long-terms study revealed the best performing herbal moisturizer.

Figure 0003: Changes in % of skin viscoelasticity measured before (baseline) and after 1,2 and 3 hr of single application of herbal moisturizers

Mentions: The changes in skin mechanical parameters observed before and after 1, 2, and 3 h after single application of moisturizers is expressed as a percentage increase in the values and are shown in Table 3. Significant increase (P < 0.01) in viscoelastic parameters, relative to baseline (before, 0 h) were observed 1, 2, and 3 h after single application of all moisturizers [Figure 3]. The most pronounced changes were observed with moisturizer HM8, HM10, and HM11 (65–75% increase), compared with HM1,3,4,13,14,17,18,19, and 20 (60–55% increase) and 40–50% increase was shown with HM2,5,6,9,7,12,15, and 16 when compared to baseline [Figure 3].
