What to do about dry, peeling skin when returning to your hometown

In general, dry and peeling skin when returning to one's hometown may be caused by a sudden drop in environmental humidity, changes in skincare habits, damaged skin barrier, aggravated seborrheic dermatitis, or dryness triggered by allergies. It is recommended to seek medical advice promptly, identify the underlying cause, and improve the condition under a doctor’s guidance through general care, medication, and other treatments. Specific causes are analyzed as follows:

1. Sudden drop in environmental humidity: If the hometown is located in northern regions or mountainous areas, the air tends to be dry during winter or seasonal transitions, accelerating skin moisture loss and leading to dryness and flaking. Use a humidifier indoors to maintain humidity levels between 50% and 60%. Wear masks and scarves when going outdoors to minimize skin exposure to dry air.

2. Changes in skincare habits: Forgetting to bring regular skincare products or using strongly alkaline soaps for facial cleansing can lead to insufficient skin hydration. Immediately resume using moisturizers containing ceramides, wash the face with lukewarm water, avoid frequent exfoliation, and apply skincare products within three minutes after washing to lock in moisture.

3. Damaged skin barrier: Environmental changes may irritate the skin and weaken its barrier function, increasing moisture loss and possibly causing mild itching. Patients may use vitamin E cream, urea-vitamin E ointment, or hyaluronic acid gel as directed by a physician to gently repair the skin barrier.

4. Worsening seborrheic dermatitis: Oily diets or irregular sleep patterns at home may trigger seborrheic dermatitis, resulting in dryness and scaling on the scalp and face. Patients should use medications such as tacrolimus ointment, pimecrolimus cream, or vitamin B6 ointment as prescribed, and adopt a light diet with reduced fat intake.

5. Dryness due to allergy: Allergic reactions caused by exposure to dust, mites, or specific plants in the hometown can induce skin inflammation, leading to moisture loss along with redness and itching. Patients should take antiallergic medications such as cetirizine hydrochloride tablets, loratadine capsules, or use calamine lotion as directed, and avoid suspected allergens.

In daily life, drink plenty of warm water and consume water-rich fruits such as pears and apples. Wear loose, breathable cotton clothing to reduce skin friction. Maintain a regular sleep schedule and avoid staying up late to enhance the skin’s natural ability to retain moisture and repair itself, thereby improving dryness and peeling.
