立春过后 天气渐暖但空气依然干燥 不少人的皮肤开始出现 频繁泛红、脱皮、瘙痒 别急着怪护肤品！ 90%的皮肤问题 都源于皮肤屏障受损 从"清洁陷阱"到"锁水密码" 3步科学护肤法 清洁→保湿→防晒 手把手教你避开90%的护肤误区 01 警惕皮肤"生病"信号 及时识别需就医的症状 屏障受损而非单纯缺水 皮肤表面存在一层由皮脂膜、角质层及水分构成的"保护罩"，类似"三明治"结构，是抵御外界刺激的第一道防线。季节交替时，气温波动、空气干燥（加 速水分流失）、紫外线增强（易被忽视却持续损伤屏障）是影响皮肤的三大外部因素。若皮脂分泌减少、水分流失增多或紫外线破坏屏障结构，保护功能 减弱，外界刺激便会侵入，引发干痒、红肿等症状。核心问题在于屏障受损，而非单纯缺水。 此外，不当护理习惯也会加剧屏障损伤。 清洁方式不当： 水温过热、使用强力清洁产品或粗糙搓澡巾（如丝瓜络）会破坏皮脂膜；频繁搓澡去角质（角质层是屏障重要组成）会直接削弱屏障。 搔抓与刺激： 用力搔抓或用刺激性护肤品（如强酸强碱类产品）会进一步损伤屏障。 及时识别需就医的症状 皮肤屏障受损后，若出现以下症状，提示可能发生炎症或病变，需及时就医： 红斑：皮肤出现片状 ...

作者: 郝迎灿,辛阳 孙志军提醒，泡温泉的时候水温不宜过高，最好控制在38—40摄氏度之间；单次浸泡以10—15分钟为 宜，起身时应放慢动作，避免因体位变化导致头晕或跌倒；适当补充水分，避免在温泉池内饮酒、吸 烟，降低意外风险。"如果觉得胸闷、心慌、头晕或者直冒冷汗，千万别硬撑，要马上离开水池，到通 风的地方休息。症状如果没缓解，一定要及时就医。"孙志军说。 中国医科大学附属盛京医院皮肤科主任医师吴严提醒，冬季洗热水澡、泡温泉需注重保护皮肤，避免损 伤皮肤屏障。"水温不宜过高，避免过度去除皮肤表面的天然皮脂膜；时间不宜过长，长时间处于湿热 环境会导致角质层水合过度，进一步削弱皮肤屏障功能，加重干燥瘙痒。"吴严说。 吴严建议，擦干身体后需在皮肤表面尚存微量水分时立即涂抹保湿霜，宜选择含神经酰胺、角鲨烷、透 明质酸等成分的产品。皮肤敏感、有湿疹等炎症性皮肤病的患者需谨慎，高温可能加重皮肤损伤，温泉 中的矿物质也可能产生刺激。 中国医科大学附属盛京医院中医科主任医师汲泓介绍，科学泡澡可帮助冬藏养生，但要遵循"适度、适 时、适人"原则：洗完后立即擦干保暖，忌吹风碰冷水；泡到微微出汗即可；饭后、饥饿、疲劳、酒后 不适合 ...

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].

Core Viewpoint - Winter skin itching is a common issue caused by environmental, physiological, and lifestyle factors, as explained by Shanghai dermatology expert Zheng Huajuan [1] Group 1: Causes of Winter Skin Itching - Environmental factors include cold winds and dry air, leading to rapid evaporation of moisture from the skin, resulting in rough and fragile skin [1] - Physiological factors involve decreased activity of sebaceous glands in winter, leading to reduced oil secretion and weakened skin barrier, which accelerates moisture loss [1] - Lifestyle habits such as using hot water for bathing and frequent use of strong cleansers can damage the skin's natural oils and exacerbate dryness [2] Group 2: Recommendations for Skin Care - Follow the principles of "warm, less, and gentle" for skin cleansing, using mild products and avoiding strong alkaline soaps [2] - After cleansing, apply moisturizing products while the skin is still slightly damp to better lock in moisture [3] - Maintain a balanced diet rich in vitamins A, C, E, and Omega-3 fatty acids, and wear soft, loose clothing to avoid skin irritation [3] Group 3: Case Study - A case study of a resident, Wang Ayi, illustrates the effectiveness of a scientifically tailored skincare regimen, leading to significant improvement in her skin condition after following expert advice [4] - The expert emphasizes the importance of seeking medical attention if itching persists or worsens to avoid delaying treatment for potential underlying conditions [4]

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].

Core Viewpoint - The article provides a skincare guide for hot and humid weather, emphasizing the importance of adjusting skincare routines and product choices to alleviate skin issues caused by high temperatures and humidity [1]. 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].
