Tetrahydrocurcumin has potent antioxidant activity and depigmentation of the skin. Centella asiatica extract can stimulate the formation of collagen, thus reducing wrinkles in aging skin. The combination of tetrahydrocurcumin (THC) and Centella asiatica extract (CAE) is expected to improve various parameters of premature aging. This study used pre-test post-test control group design. Mice were randomized into 5 test groups. The dorsal part of the mice was shaved, and then various anti-aging parameters, including skin sensitivity, moisture content, collagen levels, elasticity, and large pores, were meas-ured using a skin analyzer. Furthermore, the dorsal was smeared with a cream base for the negative control (NC) group, a cream containing ethyl ascorbyl ether for the positive control (PC) group, a cream containing THC for THC group, a cream containing CAE for the CAE group, and a cream containing THC and CAE for the Combination group, each with a dose of 2 mg/cm2 before and after UV irradiation. After treatment for four weeks, the anti-aging parameters were measured again. The combination of THC and CAE could increase the collagen and elasticity levels compared to THC and CAE itself, but the increase was not significant. Based on all anti-aging parameters scores, THC and CAE’s combination did not provide more significant anti-aging activity than single THC and single CAE.

This research empirically analyzed whether the foods which came from a non-Muslim majority country, such as South Korea, could play an important role in affecting the consumer intention in a predominantly Muslim country. Online survey methods were used to investigate the proposed hypothesis. 318 responses were used for further analysis. Forty-six reflective constructs were adapted from literature and designed by using a five-point Likert scale to facilitate measurement. Estimation models and structural models were examined through SEM-PLS analysis techniques using SmartPLS 3.0 application as the data processing tool. The results showed that religiosity and halal awareness had a positive and significant effect on attitude toward halal labels, including the mediating effect from consumer attitudes towards halal labels which had a positive but insignificant effect on purchase intention. Halal awareness plays an important role for Muslims in the decisionmaking process for purchasing food. In contrast to the initial hypothesis, the country of origin actually did not have a positive effect on attitudes towards the halal label. In a Muslim-majority country like Indonesia, findings halal food is not difficult, so this research basically is a reminder to marketers to follow those halal principles in implementing their marketing strategies.
