Core Viewpoint - The article emphasizes the importance of proper skincare during winter to combat skin dryness and itchiness, particularly for the elderly, due to environmental factors and reduced skin oil production. Group 1: Skincare Practices - After each shower, it is crucial to moisturize immediately to lock in moisture, with recommended water temperature below 40°C and shower duration limited to 10-15 minutes [1] - Moisturizing is essential, with products containing ceramides, petroleum jelly, glycerin, and hyaluronic acid being preferred to form a protective barrier on the skin [2] - Maintaining indoor humidity levels between 40%-60% and using cotton, loose-fitting clothing is advised to prevent skin irritation [3] Group 2: Dietary and Lifestyle Recommendations - Adults should aim for a daily water intake of 1500-2000 milliliters, with a diet rich in vitamins A, E, and Omega-3 fatty acids to support skin health [4] - Moderate exercise is beneficial for blood circulation, while avoiding intense activities close to bedtime is recommended [4] - Sun exposure should be balanced with sun protection to avoid skin damage from UV rays and cold winds [4] Group 3: Medical Guidance - For severe itching affecting sleep and daily life, short-term use of antihistamines or topical corticosteroids may be necessary under medical supervision [5] - Immediate medical attention is advised for persistent or worsening symptoms, especially if accompanied by other concerning signs [5] Conclusion - Proper skincare and timely intervention can help alleviate winter skin issues, ensuring comfort and health [6]

Core Viewpoint - Winter poses significant challenges for skin health due to low temperatures and humidity, leading to dryness, tightness, and irritation. Effective skincare strategies are essential to combat these issues and maintain skin hydration. Group 1: Causes of Winter Skin Issues - The combination of low temperature and humidity accelerates moisture evaporation from the skin, similar to a wet towel drying faster in a dry room [1] - Sebum production decreases in colder weather, weakening the skin's natural moisture barrier [1] - The skin barrier may already be compromised from summer exposure, making it more susceptible to dryness and irritation in winter [1] - Increased use of heating devices can further deplete skin moisture [1] Group 2: Cleansing and Exfoliation - Gentle cleansing is crucial to avoid damaging the skin barrier; hot water should be avoided, with a recommended temperature of 35°C to 37°C [2] - Use amino acid-based cleansers instead of harsh soap-based products to prevent tightness and dryness [2] - Exfoliation frequency should be reduced in winter; oily skin may exfoliate every 1-2 weeks, while dry or sensitive skin should limit it to once a month or stop altogether [2] Group 3: Moisturizing Techniques - Locking in moisture is vital; the first 60 seconds after washing is the best time to apply moisturizers [3] - Key moisturizing ingredients include humectants like hyaluronic acid and glycerin, which attract water, and occlusives like squalane and ceramides that prevent moisture loss [3] - Transition to richer creams or oils for winter skincare, as lighter formulations may not provide adequate nourishment [3] Group 4: Sun Protection - Sunscreen is essential even in winter; UV rays can still penetrate clouds and glass, causing skin damage [4][5] - A broad-spectrum sunscreen with SPF 30 PA+++ should be applied to all exposed areas [5] Group 5: Internal and External Care - Adequate hydration is fundamental; a daily intake of 1.5-2 liters of water is recommended [7] - Consuming foods rich in Omega-3 fatty acids and vitamins A, C, and E supports skin health [7] - Sufficient sleep is crucial for skin repair, often more effective than topical products [8] Group 6: Targeted Care for Specific Areas - Hands and feet are prone to dryness; applying thick creams before bed and using cotton gloves or socks can enhance moisture retention [9] - Lips should not be licked; using a lip balm with petroleum jelly or beeswax is advisable [10] - Areas with fewer sebaceous glands, like elbows and knees, require extra attention during moisturizing [11] Group 7: Advanced Skincare Solutions - For persistent dryness and skin issues, professional treatments like water light injections can provide deep hydration by delivering nutrients directly to the dermis [12] - Photorejuvenation treatments can improve skin texture and stimulate collagen production, making it an ideal option during winter [12][13]

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].
