Introduction

In general, sensitive skin during seasonal transitions may exhibit symptoms such as redness, heat sensation, dryness with flaking, itching, stinging, rashes, and reduced tolerance. During seasonal changes, significant fluctuations in temperature and humidity can easily irritate the sensitive skin barrier, causing blood vessels to dilate and resulting in widespread redness accompanied by a burning sensation. These symptoms are particularly prone to worsening in environments with frequent shifts between hot and cold conditions, and they tend to last longer.

Generally, sensitive skin during seasonal transitions may exhibit symptoms such as redness, heat sensation, dryness with flaking, itching, stinging, flushing with rashes, and decreased tolerance. Detailed explanations are as follows:

1. Skin redness and heat: During seasonal changes, significant fluctuations in temperature and humidity can easily irritate the sensitive skin barrier, causing blood vessels to dilate. This leads to widespread redness accompanied by a burning sensation. Symptoms tend to worsen in environments with frequent shifts between hot and cold temperatures and may persist for extended periods.

2. Dryness and flaking: Humidity levels drop during seasonal transitions, accelerating moisture loss from the skin. Sensitive skin has weaker water-retention ability, making it prone to dryness and tightness. In severe cases, fine flakes may appear on the skin surface, giving it a rough texture. A slight gritty or tacky feeling may occur when applying skincare products.

3. Itching and stinging: The amount of environmental irritants such as pollen and dust increases during seasonal changes. When sensitive skin comes into contact with these substances, it may trigger an immune response leading to itching, which can worsen if scratched. Some individuals may also experience brief stinging sensations when applying skincare products or coming into contact with water.

4. Flushing and rashes: After exposure to seasonal environmental stressors, small red rashes or patchy red areas may appear on regions such as the cheeks and forehead. These rashes typically do not have obvious raised bumps, but continued irritation may lead to mild swelling, affecting the skin's appearance.

5. Reduced tolerance: Skincare products that were previously well-tolerated may cause discomfort during seasonal changes—such as feelings of greasiness, clogged pores, or irritation. Additionally, the skin’s resistance to external stressors like UV radiation and wind decreases, making it more susceptible to skin issues even with minimal protection.

During seasonal transitions, it is recommended to reduce the frequency of skin cleansing and choose gentle, non-irritating cleansers. Enhance skin hydration by using moisturizing products containing ceramides and hyaluronic acid to help repair the skin barrier. Practice sun protection when outdoors and avoid prolonged exposure to harsh environments. If symptoms become severe, seek medical attention promptly and avoid self-treatment with irritating products.

What are the benefits and drawbacks of long-term use of cold water for facial cleansing?

Benefits of long-term use of cold water for facial cleansing include pore tightening, enhanced skin tolerance, reduced excessive sebum secretion, improved blood circulation, and delayed skin aging. Drawbacks include inadequate cleansing, potential induction of sensitive skin, worsening acne, impaired absorption of skincare products, and facial discomfort due to cold exposure. The choice should be made according to individual skin type. Cold water can stimulate the constriction of skin blood vessels.

What causes red patches on the face after being exposed to wind, and what should be done about it?

Red patches on the face after exposure to wind may be caused by dry and sensitive skin, cold wind-induced vasoconstriction, contact dermatitis, seborrheic dermatitis, or rosacea. Appropriate measures such as daily skincare or medical treatment can be chosen based on the specific situation. It is important to enhance facial moisturization and use gentle skincare products. Avoid going outdoors during windy weather, and when外出 (going out), take proper wind and sun protection measures.

Why does my face feel hot and turn red whenever I play video games?

In general, facial flushing and redness during gaming may be caused by emotional excitement leading to blood vessel dilation, poor heat dissipation in enclosed environments, sensitive skin, rosacea, or cholinergic urticaria. It is recommended to seek medical advice promptly, identify the underlying cause, and receive appropriate treatment under a doctor's guidance. During daily gaming, pay attention to limiting duration and avoid staying up late.

Why does the skin become itchy when subjected to vibration, and what should be done about it?

In general, skin may become itchy when exposed to vibration, possibly due to dry and sensitive skin, hypersensitive nerve endings, cholinergic urticaria, dermatographism, eczema, or other causes. Patients can choose appropriate management approaches such as general care or medication based on their specific condition. Daily moisturizing skincare is important; use gentle skincare products and actively avoid known triggers of vibration.
