Core Viewpoint - The article discusses the concept of "oil-based skincare" and its effectiveness, emphasizing the importance of understanding the types of oils suitable for skin care and the need for a comprehensive moisturizing strategy rather than relying solely on oils [1][8]. Group 1: Understanding "Oil" in Skincare - The term "oil" in skincare refers to specific types of oils, not cooking oils like lard or canola oil, which are unsuitable for skin application [1]. - Common skincare oils include plant oils (e.g., coconut oil, jojoba oil) that are rich in fatty acids and help moisturize the skin [4]. - Mineral oils, such as dimethicone, provide moisturizing and skin conditioning effects by forming a protective barrier on the skin [5]. Group 2: Mechanism of "Oil-Based Skincare" - The principle behind "oil-based skincare" is that human skin contains natural lipids, and applying additional oils can help restore the lipid layer, preventing moisture loss and dryness [7][8]. - However, relying solely on oils for hydration is insufficient; a balanced approach considering skin type and environmental factors is necessary [8]. Group 3: Selecting Moisturizing Products - A good moisturizing product should not only contain oils but also effectively provide hydration and maintain skin softness and health [8]. - Key tips for selecting moisturizing products include understanding skin type, checking ingredient lists, considering seasonal changes, evaluating brand reputation, and assessing personal experience with the product [9][10][11][12][13]. Group 4: Key Ingredients for Moisturization - Effective moisturizing ingredients include hyaluronic acid, glycerin, ceramides, and plant oils, which help retain moisture and restore the skin barrier [15]. - Ingredients to avoid, especially for sensitive skin, include excessive fragrances, alcohol, and irritating chemicals [10].

Core Viewpoint - The research identifies a novel bile acid receptor, MRGPRE, activated by a microbial amino-acid-conjugated bile acid, tryptophan-cholic acid (Trp-CA), which plays a significant role in glucose homeostasis and offers new targets for drug development in metabolic diseases like type 2 diabetes [3][4][5]. Group 1: Discovery of Trp-CA and MRGPRE - The study reveals that Trp-CA is significantly reduced in type 2 diabetes (T2D) patients, with its abundance negatively correlated with clinical blood glucose indicators [5]. - Trp-CA improves glucose tolerance in diabetic mice, indicating its potential therapeutic effects [5]. - Unlike traditional bile acids that activate FXR and TGR5 receptors, Trp-CA specifically activates the orphan G protein-coupled receptor (GPCR) MRGPRE [5][6]. Group 2: Mechanism of Action - The research elucidates the mechanism by which Trp-CA regulates GLP-1 secretion through two pathways: MRGPRE-Gs-cAMP and MRGPRE-β-arrestin-1-ALDOA, with the latter being a previously unknown mechanism [6][8]. - GLP-1 is known to promote insulin secretion, thereby contributing to blood glucose regulation [6]. Group 3: Implications for Drug Development - The findings provide a new paradigm for understanding the physiological significance of microbial-derived bile acids and pave the way for further research on amino-acid-conjugated bile acids (MABA) [4][8]. - The study suggests that Trp-CA could lead to the development of new glucose-lowering drugs without the side effect of itchiness associated with traditional bile acids [8].
