Although babies with atopic dermatitis can be seen all year round, many babies’ atopic dermatitis recurs and worsens in the fall and winter, which may be related to the dry air in the fall and winter, which aggravates the baby’s skin barrier dysfunction. The disease best occurs on the baby’s face, scalp and ear roots, manifesting as symmetrical erythema, pinhead-sized red papules, scales, and in severe cases, redness, small blisters, vesicles and oozing, etc. In severe cases, the baby’s trunk, limbs, back of the hands and feet, nipples and even the mouth and lips can be involved. And as the baby grows older, the typical hypertrophic mossy rash will gradually appear in the folds of the elbow sockets, leg sockets and neck. Countermeasure: When flowing vesicles, apply cold compresses with 3 boric acid water 3 times a day for 20 to 30 minutes each time, cold compresses can quickly reduce the edema and exudation of the skin. After cold compress, topical zinc oxide oil can be applied locally. After the exudation is reduced, topical glucocorticoid cream of appropriate strength can be applied under the guidance of a doctor. If the baby’s skin is not suitable for topical hormones, babies over 2 years old can choose 0.03 tacrolimus cream or 1 pimecrolimus ointment. These two creams are relatively new topical creams for atopic dermatitis, and their ingredients are calcium-regulated neurophosphatase inhibitors, which are not hormones themselves and are relatively safe for long-term use. It is also important to note that moisturizing moisturizing creams should be used consistently over time to protect and restore your baby’s skin barrier function, both during the flare-up and remission phases of the disease.
