Eczema, especially atopic dermatitis, tends to flare up in winter. The cold and dryness can lead to itching and scratching of the skin, and the increase in upper respiratory infections in winter can also trigger or aggravate eczema. Therefore, it is important to add clothes in time for the arrival of winter, and the room temperature should be appropriate, preferably using a humidifier. If eczema flares up, seek medical attention and your doctor will prescribe medication for the winter season. In addition, some severe eczema, which is actually atopic dermatitis, requires more formal treatment. The Department of Dermatology at Peking University People’s Hospital is the leader of the National Research Center for Eczema/Atopic Dermatitis, which specializes in the treatment of refractory eczema and atopic dermatitis. The “China Eczema Treatment Guidelines” and “China Atopic Dermatitis Treatment Guidelines” developed by our department have been proven to be the best treatment protocols and are currently being promoted nationwide. Don’t be afraid of eczema, if you treat it regularly, you can beat it.
