What to do about dry, peeling skin in teenagers

Skin dryness and peeling in adolescents are generally caused by improper cleansing methods, insufficient environmental humidity, xerotic eczema, atopic dermatitis, ichthyosis, or other reasons. It is recommended to seek medical advice promptly, identify the underlying cause, and then improve the condition under a doctor's guidance through general management, medication, and other treatments. Specific analyses are as follows:

1. Improper cleansing: Frequent use of soap-based facial cleansers or washing with hot water can damage the skin barrier and lead to moisture loss. Immediately switch to a gentle amino acid-based facial cleanser. Keep facial cleansing water temperature between 32–35 °C, limit face washing to no more than twice daily, and apply moisturizing lotion within 3 minutes after cleansing.

2. Insufficient environmental humidity: Dry air during autumn and winter or prolonged exposure to air-conditioned environments accelerates skin moisture evaporation. Use a humidifier to maintain indoor humidity between 45% and 60%. Wear a mask outdoors to protect skin from cold wind, and carry a non-irritating moisturizing mist for frequent use.

3. Xerotic eczema: Inflammation caused by impaired skin barrier function leads to dry, flaky skin accompanied by itching, commonly affecting limbs and trunk. Avoid scratching. Follow medical advice to use topical medications such as hydrocortisone cream, desonide cream, or mometasone furoate cream. Apply petroleum jelly immediately after bathing to lock in moisture.

4. Atopic dermatitis: Related to genetic and immune factors, this condition features significant dry, flaky skin along with redness and itching, and tends to recur frequently. Wear loose, 100% cotton clothing. Use topical medications such as tacrolimus ointment, pimecrolimus cream, or hydrocortisone butyrate cream as prescribed. Avoid allergens such as house dust mites and animal dander.

5. Ichthyosis: A hereditary condition causing abnormal keratin metabolism, resulting in diamond-shaped scaling, typically on the extensor surfaces of limbs, with symptoms worsening in winter. Apply urea-vitamin E cream daily to soften keratinized skin. Use topical medications such as tretinoin cream, isotretinoin gel, or adapalene gel as directed by a physician. Avoid frequent exfoliation.

In daily life, increase intake of foods rich in vitamin A and omega-3 fatty acids, such as carrots and deep-sea fish. Reduce consumption of spicy and high-sugar foods, and avoid staying up late. Choose skincare products free of fragrances and alcohol to scientifically manage and improve dry skin conditions.
