Most of the rashes that are aggravated after bathing do not look serious, but suggest that the skin’s stratum corneum lacks moisture and oil, especially in the north of China, because the northern autumn, winter and spring are very dry and the water is hard. It is recommended that you reduce the number of hot baths, especially not saunas, and apply topical emollients every day after bathing, especially pharmaceutical and non-additive products rather than some hormonal ointments. In addition, do not scratch or use hot water after itching, because that will only increasingly aggravate the rash, making the original smooth skin rash prominence, increased pigmentation, while mental irritability will also aggravate the itchy feeling. Finally, I remind you that it’s summertime and people don’t care about moisturizing their extremities, so in the fall the old disease may return, so it’s advisable to rub moisturizing cream every day now to avoid autumn troubles!
