Core Viewpoint - The article discusses the concept of "oil-based skincare" and its effectiveness, emphasizing that while certain oils can be beneficial, they should not be relied upon solely for hydration and must be used in conjunction with other moisturizing ingredients [1][12]. Group 1: Understanding "Oil" in Skincare - The term "oil" in skincare refers to specific types of oils, primarily plant oils (like coconut oil and jojoba oil) and mineral oils (like dimethicone), which can help moisturize and protect the skin [3][5]. - Some oils, such as olive oil, may actually harm the skin barrier due to their fatty acid structure [3]. Group 2: Mechanism of "Oil-Based Skincare" - The skin naturally contains lipid substances that help maintain its barrier; using additional oils can help restore this lipid layer, preventing moisture loss and dryness [7]. - However, oils alone do not provide hydration as they do not contain water, and relying solely on them can lead to continued dryness, especially in arid conditions [9]. Group 3: Limitations of Using Oils - Excessive use of oils can exacerbate acne and other skin issues, as they may promote the growth of acne-causing bacteria [10]. - Some oils may not be easily absorbed by the skin, leading to a greasy feeling without providing adequate moisture [11]. - Oils primarily create a barrier to prevent moisture loss but do not offer additional benefits like hydration or repair [11]. Group 4: Selecting Moisturizing Products - Effective moisturizing products should focus on providing sufficient hydration and preventing moisture loss, rather than just containing oils [14]. - Key ingredients to look for in moisturizers include hyaluronic acid, glycerin, ceramides, and plant oils, which can enhance hydration and skin barrier function [18][20][21][22]. Group 5: Tailoring Moisturizers to Skin Type - Different skin types require specific formulations: dry skin benefits from rich, hydrating products; oily skin should opt for lighter formulations; and sensitive skin needs gentle, low-irritant products [14][15][16]. - Seasonal and climatic conditions should also influence product choice, with heavier creams preferred in dry seasons and lighter lotions in humid conditions [24]. Group 6: Importance of Brand and User Experience - Choosing reputable brands with clinical validation can provide assurance of product efficacy [26]. - Personal experience and feedback from similar skin types are crucial in determining the effectiveness of a moisturizer [27].

中新网上海12月8日电 (陈静 喻文龙)冬季皮肤瘙痒是一个常见的问题，但很多人并不清楚其中的原 因以及如何有效预防。上海的皮肤科专家郑华娟8日对记者介绍，"冬季皮肤瘙痒的原因主要有三个方 面，一是环境因素，二是生理因素，三是生活习惯。" 据介绍，冬季，寒风凛冽，空气干燥，空气湿度大幅下降。皮肤表面的水分会随着干燥空气快速蒸 发，角质层作为皮肤的"保护壳"，一旦缺水就会变得粗糙、脆弱，原本紧密排列的角质细胞间隙变大， 外界的刺激物(如冷空气、粉尘)更容易侵入，引发瘙痒和敏感。同时，室内外温差大，从温暖的室内走 到寒冷的户外时，皮肤血管会快速收缩又扩张，反复刺激下，皮肤的耐受度会降低，尤其是脸颊、鼻尖 等暴露部位，容易出现泛红、灼热感。 皮肤表面的皮脂腺会分泌油脂，与汗液混合形成"皮脂膜"，这层膜能牢牢锁住皮肤水分，阻止水分 蒸发。专家指出，冬季气温低，皮脂腺的活性会随之下降，分泌的油脂量减少，皮脂膜的保护力变弱， 水分流失速度加快，干燥和瘙痒就会随之而来。此外，老年人的皮脂腺功能本身就会随着年龄增长而衰 退，冬季皮肤问题会更明显；而干性肌人群天生皮脂分泌少，也是冬季皮肤敏感的高发群体。 郑华娟直言，很多人在冬季 ...

Core Viewpoint - The article discusses the impact of winter on skin health, emphasizing the importance of proper skincare routines to maintain skin barrier function and hydration during the colder months [1][5]. Skin Structure and Function - The skin has a "brick wall" structure, primarily composed of the epidermis, dermis, and subcutaneous tissue, with the outermost layer (stratum corneum) acting as a protective barrier that retains moisture and defends against external pathogens [2]. Vulnerable Populations - Certain groups, such as the elderly and individuals with sensitive skin or pre-existing skin conditions, are more susceptible to skin dryness and barrier dysfunction during winter [3]. When to Seek Medical Attention - Symptoms such as severe itching affecting sleep, widespread rashes, or skin cracks with pain indicate a need for medical consultation, as these may signify significant skin barrier damage or inflammatory conditions [4]. Winter Skincare Essentials - The primary focus of winter skincare should be on "locking in moisture" rather than just hydrating the skin, which involves selecting appropriate moisturizing products, maintaining proper skin cleansing, and applying moisturizers promptly after bathing [5][11]. Effective Moisturizing Ingredients - Three categories of effective moisturizing ingredients include: - Occlusives: Reduce water loss (e.g., Vaseline, ceramides, natural oils) [6] - Humectants: Attract moisture (e.g., glycerin, hyaluronic acid) [6] - Soothing agents: Help reduce inflammation (e.g., panthenol, dipotassium glycyrrhizate) [6]. Cleansing Practices - Recommendations for winter cleansing include bathing every two to four days, using gentle cleansers with skin-friendly ingredients, and avoiding harsh soaps [9]. Common Skincare Mistakes - Misconceptions about skincare practices can lead to further skin barrier damage, such as: - Overusing face masks (recommended frequency is two to three times a week) [12][13]. - Frequent exfoliation with scrubs or loofahs (should be limited to once a week) [12][13]. - Assuming oily skin does not require additional moisturizing (lightweight moisturizers are still necessary) [12][14].

Skincare Recommendations - Choosing the right sunscreen is crucial, with recommendations for SPF30+ and PA++ for daily use, and SPF50+ and PA++++ for prolonged sun exposure activities [5]. - Daily skin cleansing is essential due to increased oil secretion in hot weather, with advice to wash the face twice daily and use appropriate cleansing products based on skin type [7]. - It is advised to avoid thick application of skincare products in summer to prevent pore blockage and acne [9]. Mask Usage Guidelines - For regular skin, masks should be used 2 to 3 times a week, while sensitive or problematic skin should limit usage to 1 to 2 times a week, with consultation from a dermatologist if necessary [10]. - Masks should be applied for 15 to 20 minutes, with special materials allowed to extend up to 30 minutes, and sensitive skin should limit application to 10 to 15 minutes [10]. Common Skincare Misconceptions - Overuse of oil-absorbing sheets can stimulate more oil production; it is recommended to limit use to no more than three times a day and to hydrate afterward [12]. - Washing the face with ice-cold water can cause capillary expansion, leading to redness; using lukewarm water is advised [12]. - Skincare products should be chosen based on skin type, and sensitive skin should avoid high concentrations of acids or alcohol [13].
