Anti-aging is one of the top goals in the field of health care and aesthetics. Anti-aging cosmetics derived from nature are oriented to long-term development, bringing safety to users and being environmentally friendly. The aim of this study was to develop an anti-aging cosmetic formulation process based on coconut oil in combination with deer antler stem cell extract. The results show that the presence of deer antler stem cell extract added to the foundation made the serum product highly stable and helped improve skin aging significantly after 2 weeks of use. The skin site where the serum product was applied showed a smooth and elastic skin surface, with very few fine lines and shallow wrinkles. Serum reduced the number of wrinkles (48.09% compared to commercial serum (ME) and 60.31% compared to positive control (PC)), reduced skin recovery time (39.31% compared to ME and 67.1% of PC) after two weeks of use. After 2 weeks of use, collagen density increased 10.18% compared to ME and 63.76% compared to control. Epidermal thickness increased by 106.1% compared to PC and 121.7% compared to ME.
The paper examines impact the world crude oil price (WCOP) on the real effective exchange rates (REER) based on empirical evidences from Vietnam in the period from 1986 to 2019. It includes five parts. Section 1 introduces research issues. Section 2 presents an overview of the research on the relationship between the WCOP and the REER. Section 3 describes the data and research methods. In Section 4, we use the autoregressive distributed lag model (ARDLM) to study the impact of the WCOP on the REER of Vietnam. Section 5 presents the key findings and explains the results in the light of actual practices. Monthly data are divided into four periods:
