What causes stinging pain on the face when applying products in winter?

Generally, stinging sensations on the face during winter may be caused by dryness due to skin dehydration, irritation from skincare product ingredients, damaged skin barrier, sensitive skin, or seborrheic dermatitis. It is recommended to seek medical attention promptly, identify the underlying cause, and undergo symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Skin dehydration and dryness: In winter, dry air causes severe water loss from the skin’s stratum corneum, leading to stinging when skincare products penetrate. Ensure adequate daily water intake; apply hydrating toner within 3 minutes after cleansing, followed by a ceramide-containing moisturizer to lock in moisture.

2. Irritation from skincare ingredients: Skincare products containing alcohol, acids, or other irritating components can easily cause discomfort when the skin’s tolerance is low in winter. Discontinue use of such products immediately and switch to simple, gentle moisturizers, such as petroleum jelly-based creams.

3. Damaged skin barrier: Over-cleansing or frequent exfoliation can compromise the skin barrier, resulting in noticeable stinging upon application of products, often accompanied by redness and flaking. Patients may use medications such as recombinant human epidermal growth factor gel, hyaluronic acid gel, or vitamin E cream as directed by a physician, and avoid using soap-based facial cleansers.

4. Sensitive skin: Individuals with naturally thin stratum corneum become more sensitive in cold winter conditions, making them prone to stinging when applying skincare products. As prescribed by a doctor, patients may use medications such as tacrolimus ointment, pimecrolimus cream, or cetirizine hydrochloride tablets, and wear masks outdoors to protect against wind and sun exposure.

5. Seborrheic dermatitis: Winter-related disruption of sebaceous gland secretion can trigger inflammation, causing stinging along with oily, red patches. Patients should use medications such as ketoconazole cream, desonide cream, or vitamin B6 tablets as directed by a physician, and maintain a light diet with reduced intake of spicy and stimulating foods.

In daily care, keep facial cleansing water temperature between 32–35 °C to avoid skin irritation from extreme temperatures. Choose mild amino acid-based facial cleansers and limit washing to no more than three times per week. Use a humidifier indoors to maintain ambient humidity between 40% and 60%, supporting skin recovery.
